DEAR PHP TEAM, MANY THANKS AND "YOU HAVE DONE GREAT WORK". I'm sure you know ;-). But i have (found) a problem. ;-) Please give me a feedback, Thanks.

#!/usr/sbin/php
<?

$envelope["from"]="foo@bar.com";
$envelope["to"]="bar@foo.com";
$envelope["subject"]="while testing";

$part1["type"]=TYPEMULTIPART;
$part1["subtype"]="mixed";

$part3["type"]=TEXT;
$part3["sybtype"]="plain";
$part3["contents.data"]="Look at this\n\n\t";

$filename="1.tar.gz";
$fp=fopen($filename,"r");
$contents=fread($fp,filesize($filename));
fclose($fp);

$part2["type"]=TYPEAPPLICATION;
$part2["encoding"]=ENCBINARY;
$part2["subtype"]="octet-stream";
$part2["description"]=basename($filename);
$part2["contents.data"]=$contents;



$body[]=$part1;
$body[]=$part2;
$body[]=$part3;



$i=0;

while ($i <= 500) {
        $email=imap_mail_compose($envelope,$body);
        echo "$email\n\n";
        sleep(5);
        $i++;
}

?>
 
'./configure' ('--with-apache=../apache_1.3.12' this one is is not a module, is running as a cron job) '--enable-ftp' '--with-mysql=/usr/local/' '--with-pdflib' '--with-jpeg-dir' '--with-png-dir' '--with-tiff-dir' '--with-zlib' '--with-imap=/usr/src/packages/SOURCES/imap-4.7/c-client/'

The Memory usage percentage growth and growth while loop is running. Please give me a feedback.

I workaround the problem, now with base64_encode and little scripting for header of parts (about 30 lines)// email me if you want it ;-), and the memory usage with a 2MB file is stable at 1.1 % with imap_mail_compose it starts with about 8% and the VM kills it after 70 loops sending mail not only generate at about 80%, my computer does have 192M RAM.

Best regards,

Johannes

Thank you for taking the time to report a problem with PHP.
Unfortunately your version of PHP is too old -- the problem
might already be fixed. Please download a new PHP
version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
