<input id='k'></input>
<script type="text/javascript">
document.getElementById('k').onkeypress=function()
{
<?php
$db=new PDO('mysql:host=localhost;dbname=test;charset=utf8','$us','$ps');
$db->exec("UPDATE TXT SET texts=k.value");
$rl=$db->query("SELECT texts FROM TXT");
print_r($rl->fetchColumn());
?>
}
</script>

The idea is simple. A key you press (a letter) appears in updated page:

keyj.php:

[php]<input id='k'></input>
<script type="text/javascript">
document.getElementById('k').onkeypress=function()
{
<?php
$db=new PDO('mysql:host=localhost;dbname=test;charset=utf8','$us','$ps');
$db->exec("UPDATE TXT SET texts=k.value");
$rl=$db->query("SELECT texts FROM TXT");
print_r($rl->fetchColumn());
?>
}
</script>[/php]


The intention is to have text on the screen via print_r. I successfully used it in another php to exchange information with MySQL and users screen (worked).
Here - the more you type and the more k.value is the more text will be on screen (just from server).

Unfortunately something went wrong.
