PHP | file_exists( ) Function
The file's existence can be confirmed using the file_exist() function which takes the file name as an argument.
file_exist("abc.jpg")
The file_exists() function is an inbuilt function in PHP that is used to check whether or not a file or directory exists.
The path of the file or directory you want to check is passed as a parameter to the file_exists() function which returns true on success and false on failure.
Syntax:
file_exists($filename)
filename: Path to the file or directory.
Return Value:
Returns TRUE if the file or directory specified by "filename" exists; FALSE otherwise.
Let's see an example of file_exist() function.
<?php
// select file name with path
$filename = '/path/to/zone.txt';
// condition to check file exist or not
if (file_exists($filename)) {
echo "The file $filename exists";
} else {
echo "The file $filename does not exist";
}
?>
