Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

----------------

Your observation is likely due to PHP 5 tracking memory better. The
migration doc http://www.php.net/manual/cs/migration52.other.php says
'Thanks to this new-found accuracy memory usage may appear to have
increased, although actually it has not.'  

Or perhaps the new memory manager chunking and other changes to OCI8
plays a role. Calculate how much data you need to hold after fetching to
see what expectation you should have.

With large data sizes, fetching LOBs as locators (i.e. remove
OCI_RETURN_LOBS) and operating on them one by one might reduce peak
memory, depending on your output requirements.

Description:
------------
I have this function which runs well on Php 4.9 :

function lire_structure($inlist_stru,$link) {
        if ($inlist_stru=='') return '';
        $stmt = OCIParse($link,"select STRU_ID,STRU_MOLFILE from
sub_structure_view where stru_id in(".$inlist_stru.")");
        OCIExecute($stmt);
        while (OCIFetchInto ($stmt, $row, OCI_RETURN_LOBS)) {
                $i++;
                $tabstru[$row[0]]=$row[1];
                //echo "$i<br>";
        }
        return $tabstru;
}


But when I used it on php 5.2.9 :

I have this following error :
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
allocate 524288 bytes)

So I change the memory limit of php.ini from 128 M to 512 (256 m is not
enough) and the function works well.
But I'm asking why with php 4.9 where the memory limit of php.ini is
only at 8 M, the function works well?

I see in internet forum that php 5 releases memory no correctly.
Could you help me?

Actual result:
--------------
I have this following error :
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
allocate 524288 bytes)
