Add http:// prefix to URL when missing

Question

Hello I have a very simple code

    
Website
         


        

Answer 1

A simple solution which may not work in all cases (i.e. 'https://'):

if (strpos($aProfileInfo['Website'],'http://') === false){
    $aProfileInfo['Website'] = 'http://'.$aProfileInfo['Website'];
}

Answer 2

You can use this function as a general if nothing from the array is found in the string append something to it.

function httpify($link, $append = 'http://', $allowed = array('http://', 'https://')){

  $found = false;
  foreach($allowed as $protocol)
    if(strpos($link, $protocol) !== 0)
      $found = true;

  if($found)
    return $link;
  return $append.$link;
}

Answer 3

I think you'd better use the built in function parse_url() which returns an associative array with its components

something like this will work for you:

 if  ( $ret = parse_url($url) ) {

      if ( !isset($ret["scheme"]) )
       {
       $url = "http://{$url}";
       }
}

Answer 4

You could use strpos:

// Trim trailing whitespace
$aProfileInfo['Website'] = trim($aProfileInfo['Website']);

// Test if the string begins with "http://"
if (strpos($aProfileInfo['Website'], 'http://') !== 0) {
  $aProfileInfo['Website'] = 'http://' . $aProfileInfo['Website'];
}
