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.
