simple html dom parser error find function on boolean

Question

$html = file_get_html($response);
$displaybody = $html->find('div[id="item"]');
echo $displaybody->plaintext

I'm using html dom parser to and using find() funtion but i got an error like this :

PHP Fatal error: Uncaught Error: Call to a member function find() on boolean

can someone tell me why ?

do an if(find('div[id="item"]')) print true else print false. True, means dom tag exists, false means it doesn't ('item') can't be found — C0L.PAN1C

I'd suggest you output $html to debug log or console and manually see if the div id item is in fact there. $100USD says it's not there, null or blank. — C0L.PAN1C

Simple HTML Dom can react adversely in some cases as well; it's better if you use PHP's built in DOMDocument, and DOMXPath php.net/Domxpath — Kaylined

Try this answer which actually worked for me.

The reason for this error is: the simple HTML DOM does not return the object if the size of the response from url is greater than 600000. You can void it by changing the simple_html_dom.php file. Remove strlen($contents) > MAX_FILE_SIZE from the if condition of the file_get_html function. This will solve your issue.

Or just update the MAX_FILE_SIZE defined in that same file.

PHP Fatal error: Uncaught Error: Call to a member function find() on boolean

This generally means that find('div[id="item"]') is false or not found.

I'd suggest you output $html to console or log and verify that div id "item" is in fact in there.

Also use DOMDocument library and use getElementById

public DOMElement DOMDocument::getElementById ( string $elementId )

Should grab the first instance of 'item' (assuming if there's more than one you want the first one)
