Question

How to check if a image src have a blob URL or simple URL in php

Edit

You can simply say that how to check if a object in img src is blob or not?

Answer 1

You can do it before using it in the image source.

Firstly take out the link from the line SRC using regex or using DomDocument like following:
$html = ''; $doc = new DOMDocument(); $doc->loadHTML($html); $xpath = new DOMXPath($doc); $src = $xpath->evaluate("string(//img/@src)");
Then use parse_html to check if there is host and path in the url. If the parse_html results in false then the link could be stored and check for proper files using file_put_content .

Answer 2

You can use file_exists to check if it is a file.

if( file_exists( $url ) ) ){
  // it is a file
} 
else{
  // it is a blob
}
