PHP file_exists() | Check if File or Directory Exists
The PHP file_exists() function is used when we need to check whether a file or a directory exists or not. For example:
<?php
$x = file_exists("fresherearth.txt");
if($x)
echo "<p>The specified file is available.</p>";
else
echo "<p>The specified file is not available.</p>";
?>
The output of above PHP example on file_exists() function is:
Since the file fresherearth.txt is available in the current directory, therefore the above example produces the output that you have seen.
PHP file_exists() Syntax
The syntax of file_exists() function in PHP, is:
file_exists(path)
PHP file_exists() Example
<?php
$file = "fresherearth.txt";
if(file_exists($file))
echo "<p>The file, <b>$file</b> exists.</p>";
else
echo "<p>The file, <b>$file</b> does not exists.</p>";
$path = "C:\Users\DEV\jobails.com";
if(file_exists($path))
echo "<p>The path, <b>$path</b> exists.</p>";
else
echo "<p>The path, <b>$path</b> does not exists.</p>";
?>
In above program, both the file and the path exists, therefore the output produced by above PHP example should be:
