David,
I don't believe this to be a bug. In order to process the script, PHP needs to use additional memory resources. My guess is that while the original 69Mb file is loaded, the new encrypted file also needs to exist in memory.
Glad you were able to find a solution.

I did it
IT works with 256M memory allocated.
After realising the line it shown 69505726(little more )Mo as memory usage.
It's in some way really not understandable. I suppose it could be a php
bug.

I don't have a definitive answer for you, but I notice that the
memory size is less than twice the file size. Depending on the PHP
functions you are using you could be eating up a lot of memory in the
execution of the script that wouldn't necessary show up where you
inserted the debugging statements.
Does the script work with smaller files? Can you the memory_limit to
something very high, over 220 Mb, and/or test your script with
smaller files to find the threshold where the Fatal error occurs? -- Bob

I try to run your test script.
So before the file reading the memory is 125730 o, and I 'm not
able to get the next text due to error display
CURRENT MEMORY USAGE = 125720
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted
(tried to allocate 69505726 bytes)
I tried to set the memory_limit in the script and set a default
value more efficient in the php.ini
That show the same error.
Thanks for your helps

David,
Perhaps your memory usage and/or memory limit is different than
what you are assuming it is. If you add the following code to your
script, in several places if necessary, it should help you debug
it . // PRINT CURRENT MEMORY USAGE:
http://us4.php.net/manual/en/function.memory-get-usage.php
print 'CURRENT MEMORY USAGE = '.memory_get_usage().'<br />';
// PRINT CURRENT MEMORY LIMIT:
http://us4.php.net/manual/en/function.ini-get.php
print 'MEMORY LIMIT = '.ini_get('memory_limit').'<br />';
You can also set the memory limit on a per page basis
// SET MEMORY LIMIT:
http://us4.php.net/manual/en/function.ini-set.php
$mem_limit = '128';
print "SETTING MEMORY LIMIT TO $mem_limit Megabytes<br />";
ini_set('memory_limit', $mem_limit.'M');
//http://us4.php.net/manual/en/ini.core.php#ini.memory-limit
There are a variety of limitations and restrictions to the
commands noted above, be sure to read the documentation.

Hello
I got the following message.
PHP Fatal error: Allowed memory size of 134217728 bytes
exhausted (tried to allocate 69505726
bytes)
I read on several forums to increase the size of the memory limit
in php.ini.
As you can wee which as already be done cause 134217728>69505726.
But I still get the message.
I'll like to understand and find how to do.
The aim of this script is to get a big file (69MB) and to
encrypt (using mcrypt). then to send it
by ftp.
Thanks for your helps
david
