To Check URL Existence It Takes Only Two Steps:-
- Make a HTML file to send URL
- Make a PHP file to check URL
Step 1. Make a HTML file to send URL
We make a HTML file and save it with a name send_url.html
<html> <body> <div id="wrapper"> <div id="url_form"> <form method="post" action="check_url.php"> Enter URL : <input type="text" name="url"> <input type="submit" name="submit_url" value="CHECK URL"> </form> </div> </div> </body> </html>
I n this step we create a form to enter URL for checking by user.
Step 2. Make a PHP file to check URL
We make a PHP file and save it with a name check_url.php
<?php
if(isset($_POST['submit_url']))
{
$url = $_POST['url'];
$url_headers = @get_headers($url);
if(strpos($url_headers[0],'200'))
{
$exist = "URL Exist";
}
else
{
$exist = "URL Does Not Exist";
}
}
?>
In this step we get the URL value submitted by user and then by using PHP get_headers() function we get all the headers of that URL and it return headers array and then we check '200' is present in array's 1st
value if yes then the URL is exist and running and if not URL is not running or exist.'200' is URL status '200' means URL is running.
