Your double quotes and single quotes are weird. I suspect a keyboard problem..

The normal single quote that PHP accepts is ', yours is ‘

The normal double quote that PHP accepts is ", yours is “

Your fixed code would be:

<?php
include_once('simple_html_dom.php');
$target_url = "http://www.xyz.com/";
$html = new simple_html_dom();
$html->load_file($target_url);
foreach($html->find('a') as $link){
echo $link->href."<br />";
}

?>

I think you're just using wrong quotes for your string.

Wrong: “string“

Right: "string"

Or: 'string'

Please check your keyboard settings

It seems you have copy paste this code . Wrong single and double quotes in your block of code. change “ to " and ’ to ' . Your correct block of code are :-

<?php
    include_once('simple_html_dom.php');
    $target_url = "http://www.example.com/";
    $html = new simple_html_dom();
    $html->load_file($target_url);
    foreach($html->find('a') as $link) {
        echo $link->href."<br />";
    }
?>

from what you have pasted, your have not used a proper double quote to encapsulate your string $target_url = "http://www.xyz.com/"; use "
