help me with the code
$homepage = file_get_contents('index.html');
foreach($homepage->find('table') as $table){
// returns all the <tr> tag inside $table
$all_trs = $table->find('tr');
$count = count($all_trs);
echo $count;
}
i am trying to get content of index.html and then count the number of tr tags but the above code isn't working.
You can use the DOM API for this purpose:
$dom = new DOMDocument;
$dom->loadHTMLFile('index.html');
$tr_count = $dom->getElementsByTagName('tr')->length;
I'm not entirely sure what context this code is in, but you can use file_get_contents() and substr_count() to do what you want.

http://php.net/manual/en/function.substr-count.php
echo substr_count(strtolower(file_get_contents('index.html')), '<tr>');
