Let's assume the file foo.txt with read only permissions or 744 chmod and the owner of the PHP-FPM process is not the same as foo.txt, if you try to write something in it with the function file_put_contents you'll get a "503 service unavailable" response from apache plus a ambigous warning in the error log:

22-Mar-2015 17:47:27 Europe/Paris] PHP Warning:  file_put_contents(foo.txt): °¶»áÈ in /var/www/xxx/api/Library/Log.php on line 121

While using respectively fopen(), fwrite(), and fclose() on the same file with the same conditions and appropriate controls will produce nothing.

My PHP version is 5.6.4

Test script:

//foo.txt has 444 chmod or PHP-FPM user doesn't have the appropriate write permissions on the file

//This makes PHP-FPM crash
file_put_contents('foo.txt', 'Whatever', FILE_APPEND);//Makes PHP-FPM crash

//While this doesn't
$fpLog = @fopen($path, 'ba+');
if ($fpLog) {
	@fwrite($fp, $content);
