On Linux, however, file_get_contents() and others may succeed, even if file_exists() returns FALSE (Windows returns TRUE). The test script is supposed to be placed in ext/standard/tests/streams/ and to be run from the php-src root. Test script: --------------- <?php $path = "foobar://google.com/../../INSTALL"; var_dump(file_exists($path)); var_dump(file_get_contents($path, false, null, 0, 10)); ?> Expected result: ---------------- Warning: file_exists(): Unable to find the wrapper "foobar" - did you forget to enable it when you configured PHP? in %s on line %d bool(true) Warning: file_get_contents(): Unable to find the wrapper "foobar" - did you forget to enable it when you configured PHP? in %s on line %d string(10) "For instal" Actual result: -------------- Warning: file_exists(): Unable to find the wrapper "foobar" - did you forget to enable it when you configured PHP? in %s on line %d bool(false) Warning: file_get_contents(): Unable to find the wrapper "foobar" - did you forget to enable it when you configured PHP? in %s on line %d string(10) "For instal" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76857&edit=1
