检查div ID是否在PHP中存在

Question

I have same php to generate HTML in 2 ocasions:

1. Generate a link with target="_new" ;
2. Generate a link without target property.

The only way that I have to differentiate both of them is to create the parent div as different ID (eg: <div id="new"> for the 1st, '' for the 2nd.

Is there any way to check if has some #new in html and them set target?

Here's the way that I've tried so far:

<?php $new = $html->find("#new"); ?>
<a href="<?php echo $item->getPrimaryLink()->getUrl(); ?>" <?php if (is_object($new)): ?> target="_new" <?php else : ?> <?php endif; ?> >

Answer 1

If you are following HTMLDOMPARSER then you can follow:

$html = file_get_html('http://www.google.com/');
$is_new_exist=false;
if($html->find('div#new'))
$is_new_exist=true;

And now you can use that flag for your checking

For further query please checkout HTMLDOMPARSER

I would presume you would be able to use something like

$new = $html->find("#new");
if ($new) {
    echo something
} else {
    echo something else
}

Based on the assumption you are using domdocument or a html parser.

You would not use target however but rather do something like <a href="#new" or if it were on another page <a href="somepage.php#new"
