php - simple_html_dom for faster retrieval -


i trying web scraping using simple_html_dom. want inner text of span element only. have load entire page that? taking lot of time since running in loop. other alternatives faster?

here doing now-

$html = file_get_html($url); foreach($html->find('span') $element) {     if($element->innertext=="some text") {         $html->clear();         unset($html);         break;     }     else {         //do         }

this slow if used inside loop. faster way this?

i not sure speed, instead of doing foreach loop, can

$html->find( $selector, $idx )

<?php   $html = file_get_html( $url );   if ( is_object( $html ) ) {     if ( $span = $html->find( "span", 0 ) ) {       $span->innertext  = "some text";     }   } ?>
