Fatal error from phpmailer class - php

Question

I have made a php page that sends an email message with multiple attachments.
The loop which i used to attach multiple attachments and to check the size of attachments is ,
foreach(array_keys($_FILES['attach']['name']) as $key)
{
$filesize = $_FILES['attach']['size'][$key];
$extention = pathinfo ($_FILES['attach']['name'][$key] ,PATHINFO_EXTENSION
);
$name=$_FILES['attach']['name'][$key];
$data=($_FILES['attach']['tmp_name']);
$totalsize = $totalsize + $filesize;
if($totalsize > 10000000) //10mb10000000
{$err="<font color=#990000 size=1>File exceeded maximum allowed limit of 10
Mb</font>";}
else{
$source = $_FILES['attach']['tmp_name'][$key];
$filename = $_FILES['attach']['name'][$key];
$mail->AddAttachment($source, $filename);
}
}//end Foreach loop
But when i try to attach a large file i get this error from the phpmailer class.
Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate
7355049 bytes) in /var/www/dev01/maiarn/Email/class.phpmailer.php on line 1677
Any body who can guide me Please.

Answer 1

You might want to increase the PHP memory limit. If you're working on your development machine, you could search for the php.ini file and modify the memory_limit (which often defaults to 16M). Change that to f.e. 128M and restart your webserver.
If you want to see it change, you can use the following line to show the configuration currently in use:
<?php phpinfo(); ?>

Answer 2

Let PHP use more memory on this script only by using the following PHP code:
ini_set(‘memory_limit’,’64M’);
