I am trying to use file_get_contents on a file but get the error below:
Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 187260544 bytes) in /dir/public_html/dir/file.php on line 18
Unless I am mistaken the allowed maximum is greater than what I am trying to use so why the error? Is there another setting that needs to be taken into account?
分享 The total memory used by your code cannot exceed your maximum memory allowed. If you call memory_get_usage (http://php.net/manual/en/function.memory-get-usage.php) just before you do file_get_contents you'll probably find that the amount there + the 187260544 btyes for the file you want to load exceed the maximum allowed of 187260544 btyes.
If so then you have other variables in memory using up a lot of memory. If you're loading other files into memory, consider clearing them (if you can) before loading this one (using unset) or consider streaming the file instead by reading it line by line using fgets (http://php.net/manual/en/function.fgets.php) or using PHP streams (http://php.net/stream).
