Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ',' or ';'

<?php
function paypal_items() {
 $num = 0;
 foreach($_SESSION as $name => $value){
     if($value != 0){
	     if (substr($name, 0, 5) == 'cart_') {
			 $id = substr($name, 5, strlen($name) -5);
			 $get = mysql_query('SELECT id, name, price, shipping FROM products WHERE id='.mysql_real_escape_string((int)$id));
			 while ($get_row = mysql_fetch_assoc($get)) {
			     $num++;
				 echo '<input type="hidden" name="item_number_'.$num'" value="'.$id.'" />';
				 echo '<input type="hidden" name="item_name_'.$num.'" value="'.$get_row['name'].'" />';
			     echo '<input type="hidden" name="amount_'.$num.'" value="'.$get_row['price'].'" />';
				 echo '<input type="hidden" name="shipping_'.$num.'" value="'.$get_row['shipping'].'" />';

Giving a line number will speed up answers.  Just a heads up.

 

Here lies the problem.

echo '<input type="hidden" name="item_number_'.$num'" value="'.$id.'" />';  //You have missed a period (.)(dot) after $num.
