Bug description: gzcompress() function doesn't work on a large file
Description:
------------
I tried using the ZipFile class I found somewhere else to compress files
and produce a zip file. But when my input file is larger than 6 megabytes
in size, I don't get a zip/compressed file. I debugged the ZipFile class
and found out that gzcompress() function doesn't work with a large file
e.g. 6 MB file.
So, in order to compress my 6 MB file and produce a zip file, I just used
the ff. line of code:
system("zip $zipfile_name $file_name > /dev/null", $return_val);
Reproduce code:
---------------
#!/usr/bin/php #phptest.php
<?php
$file = "ATD335R1.208"; #some file here
$fp = fopen($file, "r");
if($fp) {
$data = fread($fp, filesize($file));
fclose($fp);
}
$unc_len = strlen($data);
$crc = crc32($data);
$zdata = gzcompress($data); #HERE'S WHERE AN ERROR OCCURS
print "GZCOMPRESS DONE..".strlen($zdata);
?>
Expected result:
----------------
"GZCOMPRESS DONE.."
Actual result:
--------------
PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to
allocate 6945661 bytes) in /var/www/html/phptest.php on line 17
