仅当脚本标记的src包含PHP中的特定单词时才提取

I am learning PHP. I have to extract all the script tags of a particluar $url whose src contain a particular word say 'abc'.

I have tried this:

                $domd = new DOMDocument();
                @$domd->loadHTML(@file_get_contents($url));
                $data = array();
                $items = $domd->getElementsByTagName('script');
                foreach($items as $item) {
                 if($item->hasAttribute('src')){
                    $data[] = array(
                   'src' => $item->getAttribute('src')
                  );
                 }
                }
                print_r($data);
                echo "
";

The above code gives me the list of all the script tag's src's present in the $url.

But how should i check if a src in a script tag contains a word 'abc' ?

If you need to check each value in the array, to see if it contains 'abc', try a foreach() loop with an if statement using strpos() to see if the value contains 'abc', and then do something with it.

Something like this should do the trick:

foreach( $data as $key=>$value ) {
    if( strpos( $value['src'],'abc' ) !== false ) {
       //do something with it here
    }
}

Just edited this. Call the ['src'] element of the subArray and use that in strpos(). Alternately, you could change your line that builds the $data array to this, since you only have one element in each subArray:

if($item->hasAttribute('src')){
     $data[] = $item->getAttribute('src');
}
