PHP function file_exists()
Availability in PHP 4.0
Checks whether a file or directory exists
Parameters
| Parameter | Data type | Default value | Note |
|---|---|---|---|
$filename |
string |
not | Path to the file or directory. |
Return values
bool
true if the file or directory specified by filename exists; false otherwise.
This function will return false for symlinks pointing to non-existing files.
This function returns false for files inaccessible due to safe mode restrictions. However these files still can be included if they are located in safe_mode_include_dir.
The check is done using the real UID/GID instead of the effective one.
