PHP linkinfo() Function

The PHP linkinfo() function is used to verify if a link (pointed to by path) really exists.

Syntax

linkinfo(path)

Parameters

Return Value

Returns the st_dev field of the Unix C stat structure returned by the lstat system call. Returns a non-negative integer on success, -1 in case the link was not found, or false if an open.base_dir violation occurs.

Example:

Lets assume that we have a file called test.txt in the current working directory. The example below demonstrates on using this function to verify a link.

<?php
$target = 'test.txt'; //this file exists
$link = 'sampleTest.ttx';

echo linkinfo($target)."\n";

if(link($target, $link)) {
  echo "Link has been created.\n";
} else {
  echo "Link can not be created.\n";
}

echo linkinfo($link)."\n";
?>

The output of the above code will be:

2049
Link has been created.
