I haven't tried processing multiple large images in a single script with a memory limit before, so I haven't seen the bug before. PEL don't know anything about file handles, image resources, or similar stuff that would consume resources, so I don't see how it should leak memory. It does have a few static variables in Pel.php which could fill up. I'm thinking of Pel::$exceptions which is an array of exceptions which have been suppressed when parsing. Try calling Pel::clearExceptions() once you are done with each image -- maybe that will help. >> i'm using gd to resize my images, and pel to re-attach the exif >> data after gd has finished but i've run into a problem with the >> memory limit >> >> i'm using php 5.2.0 on fedora core 4 >> pel is updated via svn from trunk Good! >> [...] >> >> the offending code is [...] >> >> $origJpeg->loadFile($fullFilePath); Good, this uses file_get_contents() to load the file in one big swoop. The PHP manuals says that this is "the preferred way to read the contents of a file into a string. It will use memory mapping techniques if supported by your OS to enhance performance." Unfortunately file_get_contents() doens't seem to work quite as good as promised by the PHP documentation: see SF bug #1210126 where someone suggested that PEL should read the data from the files as needed. I thought that file_get_contents() would work that way since it memory maps the file. >> $exif = $origJpeg->getExif(); >> >> [...] >> >> $newJpeg = null; >> } >> $origJpeg = null; There might be a difference between assigning null to the variables and calling unset() on them. >> i am using imagedestroy, that is in another section of the code >> that is not visible here Okay good, that would have been my next question :-) -- Martin Geisler --- <[EMAIL PROTECTED]> --- http://mgeisler.net Read, write, create Exif data in PHP with PEL: http://pel.sf.net Take control of your webserver with PHP Shell: http://phpshell.sf.net
