How to check a url exist or not in php - php

Question

I want to check the url
http://example.com/file.txt
exist or not in php. How can I do it?

Answer 1

if(! # file_get_contents('http://www.domain.com/file.txt')){
echo 'path doesn't exist';
}
This is the easiest way to do it. If you are unfamiliar with the #, that will instruct the function to return false if it would have otherwise thrown an error

Answer 2

The would use the PHP curl extension:
$ch = curl_init(); // set up curl
curl_setopt( $ch, CURLOPT_URL, $url ); // the url to request
if ( false===( $response = curl_exec( $ch ) ) ){ // fetch remote contents
$error = curl_error( $ch );
// doesn't exist
}
curl_close( $ch ); // close the resource

Answer 3

Try this function on Ping site and return result in PHP.
function urlExists($url=NULL)
{
if($url == NULL) return false;
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if($httpcode>=200 && $httpcode<300){
return true;
} else {
return false;
}
}

Answer 4

$filename="http://example.com/file.txt";
if (file_exists($filename)) {
echo "The file $filename exists";
} else {
echo "The file $filename does not exist";
}
OR
if (fopen($filename, "r"))
{
echo "File Exists";
}
else
{
echo "Can't Connect to File";
}

Answer 5

I am agree with the response, I got success by doing this
$url = "http://example.com/file.txt";
if(! #(file_get_contents($url))){
return false;
}
$content = file_get_contents($url);
return $content;
You can follow the code to check the file exist at location or not.
