slt a tous,
je developpe une appli sur easyphp, et jusque la je bossais en local. aujourdui j'ai besoin d'exporter ma base vers un serveur distant. on m'a alors di de générer un fichier sql avec mysqldump et de m'en servir pour créer ma table sur le serveur distant en utilisant toujours le mysqldump. pourriez vous svp m'aider a comprednre le fonctionnement de ce mysqldump, c urgent et important, votre aide m'est d'un grand secours. merci bien.

A quoi sert mysqldump ?
A défaut d'avoir un problème réel je te conseil d aller voir ici tu trouveras a mon avis toutes les infos dont tu as besoin !
Cela étant puisque tu bossais en local avec une administration de type PHP Myadmin tu peux directement via le menu exporter ta base dans un fichier .sql, et si le systeme d administration est le meme sur ton nouveau serveur tu pourras aussi l importer via le menu...

ok, merci de m'avoir répondu. je ne passe pas par phpmyadmin pour ca car je dois automatiser la sauvegarde/restauration de la base. et comme la restauration se fait de la meme maniere que cet import vers le serveur donc je dois uniquement passer par des script php. ceci dit j'ai trouvé cette discussion qui me semble tré interessante car celui qui l'a posé cherche a faire la meme chose que moi. cependant il est allé plus loin que moi lui :

Juste une petite précision relativement au post dont tu avais mis le lien :
Sinon il existe aussi des fonctions comme shell_exec().
Je crois que la fonction est system() et non pas systeme() (faute de frappe sans doute).systeme(".chemin/vers/mysql database < tonfichier.sql");
Sinon il existe aussi des fonctions comme shell_exec().
apparemment toutes les reponses a mes questions sont dans cette discussion, cependant il y en a une qui me reste a l'esprit, et si j'ai bien compri je la pose pour confirmer. si on souhaite faire une sauvegarde de la base par un script php, on passe par la fonction system() en y fournissant la commande associée au dump c bien ca ?
Les options de mysqldump:
Ceci posé, ta commande devrait fonctionner et exporter ta base, structure et données incluses...

Dumping definition and data mysql database or table
Usage: mysqldump [OPTIONS] database [tables]
OR mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...]
OR mysqldump [OPTIONS] --all-databases [OPTIONS]
Default options are read from the following files in the given order:
C:\my.ini C:\my.cnf C:\WINDOWS\my.ini C:\WINDOWS\my.cnf C:\Program Files\MySQL\MySQL_Server_5.0\my.ini C:\Program Files\MySQL\MySQL_Server_5.0\my.cnf
The following groups are read: mysqldump client
The following options may be given as the first argument:
--print-defaults Print the program argument list and exit
--no-defaults Don't read default options from any options file
--defaults-file=# Only read default options from the given file #
--defaults-extra-file=# Read this file after the global files are read
-a, --all Deprecated. Use --create-options instead.
-A, --all-databases Dump all the databases. This will be same as --databases
with all databases selected.
--add-drop-database Add a 'DROP DATABASE' before each create.
--add-drop-table Add a 'drop table' before each create.
--add-locks Add locks around insert statements.
--allow-keywords Allow creation of column names that are keywords.
--character-sets-dir=name
Directory where character sets are.
-i, --comments Write additional information.
--compatible=name Change the dump to be compatible with a given mode. By
default tables are dumped in a format optimized for
MySQL. Legal modes are: ansi, mysql323, mysql40,
postgresql, oracle, mssql, db2, maxdb, no_key_options,
no_table_options, no_field_options. One can use several
modes separated by commas. Note: Requires MySQL server
version 4.1.0 or higher. This option is ignored with
earlier server versions.
--compact Give less verbose output (useful for debugging). Disables
structure comments and header/footer constructs. Enables
options --skip-add-drop-table --no-set-names
--skip-disable-keys --skip-add-locks
-c, --complete-insert
Use complete insert statements.
-C, --compress Use compression in server/client protocol.
--create-options Include all MySQL specific create options.
-B, --databases To dump several databases. Note the difference in usage;
In this case no tables are given. All name arguments are
regarded as databasenames. 'USE db_name;' will be
included in the output.
-#, --debug[=#] This is a non-debug version. Catch this and exit
--default-character-set=name
Set the default character set.
--delayed-insert Insert rows with INSERT DELAYED;
--delete-master-logs
Delete logs on master after backup. This automatically
enables --master-data.
-K, --disable-keys '/*!40000 ALTER TABLE tb_name DISABLE KEYS */; and
'/*!40000 ALTER TABLE tb_name ENABLE KEYS */; will be put
in the output.
-e, --extended-insert
Allows utilization of the new, much faster INSERT syntax.
--fields-terminated-by=name
Fields in the textfile are terminated by ...
--fields-enclosed-by=name
Fields in the importfile are enclosed by ...
--fields-optionally-enclosed-by=name
Fields in the i.file are opt. enclosed by ...
--fields-escaped-by=name
Fields in the i.file are escaped by ...
-x, --first-slave Deprecated, renamed to --lock-all-tables.
-F, --flush-logs Flush logs file in server before starting dump. Note that
if you dump many databases at once (using the option
--databases= or --all-databases), the logs will be
flushed for each database dumped. The exception is when
using --lock-all-tables or --master-data: in this case
the logs will be flushed only once, corresponding to the
moment all tables are locked. So if you want your dump
and the log flush to happen at the same exact moment you
should use --lock-all-tables or --master-data with
--flush-logs
-f, --force Continue even if we get an sql-error.
-?, --help Display this help message and exit.
--hex-blob Dump binary strings (BINARY, VARBINARY, BLOB) in
hexadecimal format.
-h, --host=name Connect to host.
--ignore-table=name Do not dump the specified table. To specify more than one
table to ignore, use the directive multiple times, once
for each table. Each table must be specified with both
database and table names, e.g.
--ignore-table=database.table
--insert-ignore Insert rows with INSERT IGNORE.
--lines-terminated-by=name
Lines in the i.file are terminated by ...
-x, --lock-all-tables
Locks all tables across all databases. This is achieved
by taking a global read lock for the duration of the
whole dump. Automatically turns --single-transaction and
--lock-tables off.
-l, --lock-tables Lock all tables for read.
--master-data[=#] This causes the binary log position and filename to be
appended to the output. If equal to 1, will print it as a
CHANGE MASTER command; if equal to 2, that command will
be prefixed with a comment symbol. This option will turn
--lock-all-tables on, unless --single-transaction is
specified too (in which case a global read lock is only
taken a short time at the beginning of the dump - don't
forget to read about --single-transaction below). In all
cases any action on logs will happen at the exact moment
of the dump.Option automatically turns --lock-tables off.
--max_allowed_packet=#
--net_buffer_length=#
--no-autocommit Wrap tables with autocommit/commit statements.
-n, --no-create-db 'CREATE DATABASE /*!32312 IF NOT EXISTS*/ db_name;' will
not be put in the output. The above line will be added
otherwise, if --databases or --all-databases option was
given.}.
-t, --no-create-info
Don't write table creation info.
-d, --no-data No row information.
-N, --no-set-names Deprecated. Use --skip-set-charset instead.
--opt Same as --add-drop-table, --add-locks, --create-options,
--quick, --extended-insert, --lock-tables, --set-charset,
and --disable-keys. Enabled by default, disable with
--skip-opt.
--order-by-primary Sorts each table's rows by primary key, or first unique
key, if such a key exists. Useful when dumping a MyISAM
table to be loaded into an InnoDB table, but will make
the dump itself take considerably longer.
-p, --password[=name]
Password to use when connecting to server. If password is
not given it's solicited on the tty.
-W, --pipe Use named pipes to connect to server.
-P, --port=# Port number to use for connection.
--protocol=name The protocol of connection (tcp,socket,pipe,memory).
-q, --quick Don't buffer query, dump directly to stdout.
-Q, --quote-names Quote table and column names with backticks (`).
-r, --result-file=name
Direct output to a given file. This option should be used
in MSDOS, because it prevents new line '\n' from being
converted to '\r\n' (carriage return + line feed).
-R, --routines Dump stored routines (functions and procedures).
--set-charset Add 'SET NAMES default_character_set' to the output.
Enabled by default; suppress with --skip-set-charset.
-O, --set-variable=name
Change the value of a variable. Please note that this
option is deprecated; you can set variables directly with
--variable-name=value.
--shared-memory-base-name=name
Base name of shared memory.
--single-transaction
Creates a consistent snapshot by dumping all tables in a
single transaction. Works ONLY for tables stored in
storage engines which support multiversioning (currently
only InnoDB does); the dump is NOT guaranteed to be
consistent for other storage engines. Option
automatically turns off --lock-tables.
--skip-opt Disable --opt. Disables --add-drop-table, --add-locks,
--create-options, --quick, --extended-insert,
--lock-tables, --set-charset, and --disable-keys.
-S, --socket=name Socket file to use for connection.
--ssl Enable SSL for connection (automatically enabled with
other flags). Disable with --skip-ssl.
--ssl-key=name X509 key in PEM format (implies --ssl).
--ssl-cert=name X509 cert in PEM format (implies --ssl).
--ssl-ca=name CA file in PEM format (check OpenSSL docs, implies
--ssl).
--ssl-capath=name CA directory (check OpenSSL docs, implies --ssl).
--ssl-cipher=name SSL cipher to use (implies --ssl).
-T, --tab=name Creates tab separated textfile for each table to given
path. (creates .sql and .txt files). NOTE: This only
works if mysqldump is run on the same machine as the
mysqld daemon.
--tables Overrides option --databases (-B).
--triggers Dump triggers for each dumped table
--tz-utc SET TIME_ZONE='+00:00' at top of dump to allow dumping of
TIMESTAMP data when a server has data in different time
zones or data is being moved between servers with
different time zones.
-u, --user=name User for login if not current user.
-v, --verbose Print info about the various stages.
-V, --version Output version information and exit.
-w, --where=name Dump only selected records; QUOTES mandatory!
-X, --xml Dump a database as well formed XML.
