Php – Make string that starts with http:// clickable

php

Looking to make a string that starts with either http:// or www clickable.

str_replace("http://", "$string", "<a href='$string'>");
str_replace("www", "$string", "<a href='$string'>");

shouldnt it be something like that?

Best Solution

Are you looking for something like this?

<?php
$content = 'this is a test http://www.test.net www.nice.com hi!';

$regex[0] = '|(http://[^\s]+)|i';      
$replace[0] = '<a href="${1}">${1}</a>';

$regex[1] = '| (www[^\s]+)|i';
$replace[1] = ' <a href="http://${1}">${1}</a>';

echo preg_replace($regex, $replace, $content);
?>

Update Thanks to macbirdie for pointing out the problem! I tried to fix it. However it only works as long as there is a space before the www. Maybe someone will come up with something more clever and elegant.

You can use the casting operators:

$myText = (string)$myVar;

There are more details for string casting and conversion in the Strings section of the PHP manual, including special handling for booleans and nulls.

Php – How to make asynchronous HTTP requests in PHP

The answer I'd previously accepted didn't work. It still waited for responses. This does work though, taken from How do I make an asynchronous GET request in PHP?

function post_without_wait($url, $params)
{
    foreach ($params as $key => &$val) {
      if (is_array($val)) $val = implode(',', $val);
        $post_params[] = $key.'='.urlencode($val);
    }
    $post_string = implode('&', $post_params);

    $parts=parse_url($url);

    $fp = fsockopen($parts['host'],
        isset($parts['port'])?$parts['port']:80,
        $errno, $errstr, 30);

    $out = "POST ".$parts['path']." HTTP/1.1\r\n";
    $out.= "Host: ".$parts['host']."\r\n";
    $out.= "Content-Type: application/x-www-form-urlencoded\r\n";
    $out.= "Content-Length: ".strlen($post_string)."\r\n";
    $out.= "Connection: Close\r\n\r\n";
    if (isset($post_string)) $out.= $post_string;

    fwrite($fp, $out);
    fclose($fp);
}
