Req #63617 [Opn->Wfx]: Make file_exists() case insensitive

Edit report at https://bugs.php.net/bug.php?id=63617&edit=1 ID: 63617 Updated by: aharvey@php.net Reported by: soapergem at gmail dot com Summary: Make file_exists() case insensitive -Status: Open +Status: Wont fix Type: Feature/Change Request Package: Filesystem function related Operating System: *nix PHP Version: Irrelevant Block user comment: N Private report: N New Comment: PHP relies on the underlying semantics of the file system: if the file system is case insensitive (and some file systems are or optionally can be on *nix systems — for example, HFS+ on OS X), then PHP will behave accordingly. Having PHP behave differently to other programs on the same system would definitely violate the principle of least surprise, quite aside from the (non-trivial) amount of work required. Closing Won't Fix.

This makes it difficult to migrate from Windows back to *nix. Forcing file_exists() to always be case insensitive would be of great benefit in these scenarios. I'm not sure what the engineering behind it would involve, but I thought I'd ask! Test script: --------------- <?php $dir = dirname(__FILE__) . DIRECTORY_SEPARATOR; var_dump(file_exists($dir . 'cAsE_mAtTeRs.php')); ?> Expected result: ---------------- true Actual result: -------------- false ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63617&edit=1
