How to remove https:// from URL and insert http:// instead of it in string in PHP?

Question

First, I need to check the URL string, if the protocol of URL is https, then I need to replace http in PHP. So the inputs and outputs of this php function must be like this:

Input -> https://example.com/example/https.php
Output-> http://example.com/example/https.php

Input -> http://example.com/example/https.php
Output-> http://example.com/example/https.php

nice example. quite rare here..

This will ensure it's at the beginning of the string and it's followed by ://

$input = 'https://example.com/example/https.php';
echo preg_replace('/^https(?=:\/\/)/i','http',$input);

I think regular expressions might be overkill for this situation.

Major +1 for this. Prevents problems with all the other answers thus far where there might be more than one https in a string.

@JustinSatyr I agree, this is right place for using strncmp or strpos (which is faster than strncmp in php when string begins with needle).

@ceejayoz Why do you prefer RegEx instead of Vyktor's answer ?

ceejayoz Over a year ago

@JohnUS Because a regex allows you to use things like ^ to only affect the beginning of a string, which is a useful feature in this case. Any speed differences are going to be pretty negligible if you're not a huge site like Facebook.

function remove_ssl ($url) {
    if (strpos($url, 'https://') == 0) {
        $url = 'http://' . substr($url, 7);
    }
    return $url;
}

The

strpos($url, 'https://') == 0

Is on purpose and is not === because we only want the case when the URL starts with https:// and just replace that one.

See also: http://php.net/manual/en/function.parse-url.php

...
$parsed_url = parse_url($url);
if ($parsed_url['scheme'] == 'https') {
    $url = 'http://' . substr($url, 7);
}
return $url;
...

You may have https:// multiple times in URL, it would be probably incorrect (some not URL-escaped entry) but it may happen: https://..../index.php?source=https://....

Vyktor Over a year ago

Hh, on your update, what about URLs like $url = 'http://username:password@hostname/path?arg=value#anchor';? :)) (but I like your way of thinking, +1)

Captain Insaneo Over a year ago

Well, updated again...I believe that should work. Checks if it starts with https and only should only replace the first occurrence.

Vyktor Over a year ago

You've end up with my answer .)) so now I have nothing bad to say :) maybe that strncmp and/or strpos would be faster than parse_url, but this is a proper way to check protocol.

At first you need to check https presence with strpos():

if( strpos( $url, 'https://') === 0){

(notice ===), than you may extract the all string after https:// (that's after first 8 characters, or 5 when keeping original ://) with substr():

$url = 'http://' . substr( $url, 8);

  $parse = parse_url($url);
  if($parse['scheme'] === 'https')
   {
  $url = str_replace('https','http',$url,1);
}

You can use this solution.

You can use a combination of str_pos() and str_replace() to accomplish this:

if(str_pos($input,'https:') === 0) {
    $output = str_replace('https:','http:',$input,1);
} else {
    $output = $input;
}

I think you want === 0 instead to be sure it is at the beginning of the string.

ceejayoz Over a year ago

There can be "https:" in a string more than once.

Brian Glaz Over a year ago

@JustinSatyr good call. Updated answer to only replace the first instance of 'https:' and only if found at the beginning. (Notice the 4th count parameter added to str_replace.

function replace_uri_protocol($uri, $search, $replacement){
    $parts = parse_url($uri);
    $uri = $replacement."://".$parts["host"].$parts["path"];

    if(isset($parts["query"])){
        $uri .= "?".$parts["query"];
    }       

    return $uri;
}
