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

Using PATHINFO_EXTENSION & str_replace
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;
