How to exclude image extension from string place in PHP

Question

I want to replace all the string values from example.com to sample.com excluding the image extension .png, .jpeg, .jpg etc.

$body = ' www.example.com, example.com, example.com/hello.html, example.com/logo.png, example.com/yourbaby.php , example.com/newimage.jpg, www.example.com/newimage.jpg';

//values    
$oldomain = ['example.com','www.']; 
$newdomain= ['sample.com', ''];
$excludeextension = [".png", ".jpg", ".jpeg"];

//Replace    
$body = str_replace($olddomain, $newdomain, $body);
$body = str_replace($excludeextension, '', $body);

//output    
 echo $body; 

Output i am looking for :

sample.com, sample.com, sample.com/hello.html, example.com/logo.png, sample.com/yourbaby.php , example.com/newimage.jpg, www.example.com/newimage.jpg

Expectation

https://example.com -> https://sample.com

https://www.example.com -> https://sample.com

https://subdomain.example.com -> https://subdomain.sample.com

https://www.example.com/image.png -> https://www.example.com/image.png

https://example.com/image.png -> https://example.com/image.png

Answer 1

You can do this using str_replace() and a bit of exploding and imploding.

$body = ' www.example.com, example.com, example.com/hello.html, example.com/logo.png, example.com/yourbaby.php, example.com/newimage.jpg, www.example.com/newimage.jpg';

$oldomain = ['example.com','www.']; 
$newdomain= ['sample.com', ''];
$excludeextension = ["png", "jpg", "jpeg"];

$doms = explode(',', $body);
foreach ($doms as &$dom) {
    // get extension
    $pi = pathinfo($dom);
    if ( ! in_array( $pi['extension'], $excludeextension) ){
        $dom = str_replace($oldomain, $newdomain, $dom);
    }

}
$NewStr = implode($doms);
echo $NewStr;

RESULT

sample.com sample.com sample.com/hello.html example.com/logo.png sample.com/yourbaby.php example.com/newimage.jpg www.example.com/newimage.jpg

Answer 2

1. Using PATHINFO_EXTENSION & str_replace
2. First explode than implode

$body = 'example.com, www.example.com, https://www.example.com, https://example.com, subdomain.example.com, example.com/logo.png, www.example.com/logo.png, example.com/hello/logo.png, https://example.com/logo.png, subdomain.example.com/logo.png"';

//Defined Values 
$oldomain = ["example.com", "www.example.com"];
$newdomain = "sample.com";
$excludeextension = ["png", "jpg", "jpeg", "css"];

// Split the string into an array of URLs
$urls_body_extension = explode(", ", $body);

// Loop through each URL and replace it if necessary
foreach ($urls_body_extension as &$url_body_extension) {
    $extension_body_extension = pathinfo($url_body_extension, PATHINFO_EXTENSION);
    if (!in_array($extension_body_extension, $excludeextension)) {
        foreach ($oldomain as $domain_body_extension) {
            if (strpos($url_body_extension, $domain_body_extension) !== false) {
                $url_body_extension = str_replace($domain_body_extension, $newdomain, $url_body_extension);
                break;
            }
        }
    }
}

// Join the modified URLs back into a string
$body = implode(", ", $urls_body_extension);

echo $body;
