Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Javascript (Page 1)
<script language="javascript">
 function sentMail() {
   var url;
   var to;
   url   = 'ml_compose_com.php?';
   document.form.title.value='admin (sit: mr chang n mr sairi n mr pzan)
<kambing@gmail.com>,';
   title = escape(document.form.title.value);
   if(title) 	{ url= url+'&title='+ title; }
   location = url+"&sent_mail=1";
  }
</script>

Page 2 (ml_compose_com.php)
<?php 
echo "<pre>".print_r($_GET)."</pre>";

JS treats literal new lines as delimiter.
 [2009-09-03 12:56 UTC] hafizanil at gmail dot com 
Thesolution i try is to split the string in js first
[code]
 to_array 		= to.split("<");
[/code]
Then send back to php as reference.Bug still consider as a bug.
E.g Again

address bar : test.php?mail=admin (sit: mr chang n mr sairi n mr pzan)
<kambing@gmail.com>
[code]
<?php 
echo "<pre>";
echo print_r($_GET);
echo "</pre>";
?>
[/code]

Output 

Array
(
    [mail] => admin (sit: mr chang n mr sairi n mr pzan)
)
