To check whether any file is existing or not then we can use the below-mentioned PHP function. To find the existence of the files, we use file_exists() function. This function is used to check whether a file or directory exists or not.
Syntax:
file_exists( $path )
Parameters: This function accept only one parameter $path. It specifies the path of the file or directory you want to check.
Return Value: It returns True on success and false on failure.
Errors And Exception:
- The file_exists() function returns False if the path specified points to non-existent files.
- For files larger than 2gb, some of the filesystem functions may give unexpected results since PHP’s integer type is signed and many platforms use 32bit integers.
Example: Suppose there exists a file named “file1.php”. Let’s check the existence of files “file1.php”.
PHP
<?php $filename = "file1.php"; if (file_exists($filename)) { echo "File exist."; } else { echo "File does not exist."; } ?> |
Output
File exist.
