Bug #15693: HTTP HEAD request executes entire script

From: patrick@ginx.com Operating system: FreeBSD 4.5 PHP version: 4.1.1 PHP Bug Type: HTTP related Bug description: HTTP HEAD request executes entire script Maybe this is the way it's supposed to work, but it doesn't make a whole lot of sense to me. When processing a HEAD request, mod_php executes the script as if it were a normal GET request. This is unexpected (at least to me) and can lead to unexpected results, such as duplicate execution when dealing with browsers that use a HEAD request prior to a GET request. For example, test script test.php: <?php $fp = fopen("test.out", "a"); fputs($fp, "I'm hit!"); fclose($fp); ?> and assuming test.out exists and is world-writable. HEAD /test.php HTTP/1.0 causes the file test.out to be appended to. This is not what I would expect, but maybe it's unavoidable. A workaround is to look at $_SERVER['REQUEST_METHOD'] and do nothing if it's a HEAD request.
