Question

I am using Simple html DOM to parse different elements from submitted html documents. I have been trying to figure out how to check for the following

<meta http-equiv="refresh" content="100">

I have tried to use.

foreach($html->find('meta') as $element){
    if($element->http-equiv=='refresh'){ refreshFound(); }
}

I receive the error Use of undefined constant equiv. Is there a special way I have to form the statement due to the – symbol?

Answer 1

It should be $element->attr

foreach ( $html->find('meta') as $element ) {
    var_dump($element->attr);
}

Output

array
  'http-equiv' => string 'refresh' (length=7)
  'content' => string '100' (length=3)
array
  'http-equiv' => string 'Content-Type' (length=12)
  'content' => string 'text/html; charset=utf-8' (length=24)
array
  'name' => string 'robots' (length=6)
  'content' => string 'noindex' (length=7)

Simple Check

foreach ( $html->find('meta') as $element ) {
    foreach ( $element->attr as $key => $value ) {
        if ($key == "http-equiv" && $value == 'refresh') {
            echo "FOUND";
        }
    }
}

Output

FOUND 

Note*

if you use $element->attr["http-equiv"] Directly it would generate the error below because sites sometimes don’t have http-equiv

Notice: Undefined index: http-equiv
