Question

I have written a PHP code that fetches website images from my other website (both are on separate hosting)

$listings['pic'][$count] = $critem[2];  

The $critem[2] sometimes returns either 1 or 2

1. https://www.example.com/wp-content/plugins/featured-content-gallery/scripts/mootools.v1.11.js

2. /wp-content/uploads/2017/07/Sidetracks-Main-1.jpg

What I am trying to do is Find

http://www.example.com and replace with https://www.example.com and if there is no domain in the $critem[2] as in the (2nd example) append https://www.example.com to the string

I am stuck as str_replacedoes not work in this criteria

Answer 1

Something like this?

$arr = ["http://www.example.com//wp-content/uploads/2017/07/Sidetracks-Main-1.jpg", "/wp-content/uploads/2017/01/45432.jpg", "/wp-content/uploads/2016/07/39223.jpg"];

foreach($arr as &$link){
    $link = str_replace("http://", "https://", $link);
    if(substr($link,0,8) != "https://") $link = "https://www.example.com" . $link;
}

Var_dump($arr);

It replaces http with https if it's in the string.
And if the link does not have the http, it adds it with the str_replace
