#125 file_get_html - empty string

[Rob_M]

When I connecting with $html = file_get_html("www.example.com") and server have opened port 80 but is empty (not have html code), function (for example) $html->find('a') is crashing...

Close this ticket, is a timeout error and php code.

An empty string is considered to be false, there is no analysis of the DOM of the page, and then immediately run you $dom->find, find method is running on a non-object (false), then you run the str_get_html function, and is necessary to check if it is false then the script has finished running, otherwise proceeds normally.

$dom = file_get_html( 'https://www.google.com/' );

if ( !$dom ) {
    die( 'Error' );
}

$tables = $dom->find( 'table' );
