#40231 [NEW]: file_exists incorrectly reports false

From: RQuadling@php.net Operating system: Windows XP SP2 PHP version: 5CVS-2007-01-25 (snap) PHP Bug Type: Scripting Engine problem Bug description: file_exists incorrectly reports false Description: ------------ Latest release fails to find files using file_exists. 2 different computers, both Windows XP SP2. In both cases the allow_url_xxx settings are the same (the only thing I can think of which may affect this). The code was run via the command line. Copying the PHP installation from the working machine to the non-working machine results in 2 working machines. The only files altered exist within C:\PHP5. No other settings or ini files have been altered between releases. Reproduce code: --------------- @echo off echo Find file using normal DOS command. echo =================================== dir \\bandexch\bandvulcfaxesreceived\2007\01\25\2007-01-25__00-00__Page-0001__9FNM7E.tif echo. echo. echo Report PHP Version. echo =================== php -v echo. echo. echo Find the same file using PHP's file_exists command. echo =================================================== php -r "var_export(file_exists('\\\\bandexch\\bandvulcfaxesreceived\\2007\\01\\25\\2007-01-25__00-00__Page-0001__9FNM7E.tif'));" Expected result: ---------------- Find file using normal DOS command. =================================== Volume in drive \\bandexch\bandvulcfaxesreceived has no label.
