Una cosa del genere:
whattime.php
Codice PHP:
<?php
# start the session, and clear any existing values
session_start();
$_SESSION['js_count'] = 0;
?>
<HTML>
<head>
<title>PHP & Javascript - Example</title>
<STYLE type='text/css'>
/* set Body display properties to make things pretty */
body, p, th, td {
font-family: Tahoma, Arial, Helvetica, sans-serif;
font-size: 11px;
}
</STYLE>
<SCRIPT type="text/javascript">
function attach_file( p_script_url ) {
// create new script element, set its relative URL, and load it
script = document.createElement( 'script' );
script.src = p_script_url;
document.getElementsByTagName( 'head' )[0].appendChild( script );
}
</SCRIPT>
</head>
<body>
[url="javascript:attach_file( 'javascript.php' )"]What time is it?[/url]
<span id="dynamic_span" />
</body>
</HTML>
javascript.php :
Codice PHP:
<?php
# set appropriate content type - to tell the browser we're returning Javascript
header( 'Content-Type: text/javascript' );
# start the session
session_start();
# determine the current time
$time = date( 'g:i a' );
# determine how many times the user has called the function, then increment it
$js_count = ( ++$_SESSION['js_count'] );
# based on the count, set the appropriate display value
if ( $js_count == 1 ) {
$inner_html = "This is your first time asking. It is $time.";
} else if ( $js_count <= 3 ) {
$inner_html = "You have asked me $js_count times now. It is $time.";
} else {
$inner_html = "You have already asked me $js_count times. Shut up!";
} # END big-nasty-else-if-block
?>
// retrieve span object, and attach additional HTML to it
dynamic_span_obj = document.getElementById( 'dynamic_span' );
dynamic_span_obj.innerHTML += '<?php echo $inner_html; ?>
';
Per dati l'idea poi lo adatti alle tue esigenze.
