Even so, a function returning less than 100K shouldn't exhaust 32M of memory either, unless something else is at play. If there is a memory limit being reached, PHP should log either an error or warning (I can't remember which). Andrew

Maybe try to specify the number of $maxlen bytes to read? http://us4.php.net/file_get_contents string file_get_contents ( string $filename [, bool $use_include_path = false [, resource $context [, int $offset = -1 [, int $maxlen = -1 ]]]] ) You could also do it the faster and "old fashioned" way: $fh = fopen('/tmp/test.zip', 'r'); $data = fread($fh, filesize('/tmp/test.zip')); fclose($fh); Or if it's multibyte maybe try this: function file_get_contents_utf8($fn) { $content = file_get_contents($fn); return mb_convert_encoding($content, 'UTF-8', mb_detect_encoding($content, 'UTF-8, ISO-8859-1', true)); } |
