duda en obtener datos de web con php

[xoceunder]

Estoy usando esto

Código PHP:

<?php
include('simple_html_dom.php');
 
date_default_timezone_set('America/New_York');
 
$link = 'http://www.ontvtonight.com/guide/listings/channel/69022174/wcbs-hdtv.html';
 
 
$html = file_get_html($link);
$date = array();
$titulo = array();
$tabla = array();
foreach($html->find('tbody tr') as $key=>$value) {
    foreach($html->find('tbody tr td h5.thin') as $row) {
        if(!$row->find('a')) {
     $date[] = preg_replace("/[\r\n\t]+/", "",$row->plaintext);
        }
    }
    foreach($html->find('tbody tr td h5.thin a') as $row) {
     $titulo[] = preg_replace("/[\r\n\t]+/", "", $row->plaintext);
    }
    $tabla[$date[$key]] = $titulo[$key];
} 
 
$array = $tabla; 
 
$copiar = 0;
$fecha_actual = date("h:i a");
$array_final = [];
 
foreach($array as $date => $value){
  if($date >= $fecha_actual)  $copiar = 1;
  if($copiar == 1)            $array_final[$date] = $value;
}
 
echo "<pre>",print_r($array_final),"</pre>";  
?>
 

pero no me quiere funcionar
