Question

I’ve got an array where PLACEHOLDER is a placeholder for the variable $value that I get later in the code:

$names = array(
    "<a href='http://skyler.com' title='PLACEHOLDER'>Skyler</a>",
    "<a href='http://jesse.com' title='PLACEHOLDER'>Jesse</a>",
    "<a href='http://walter.com' title='PLACEHOLDER'>Walter</a>",
    "<a href='http://skyler.com' title='PLACEHOLDER'>Skyler</a>",
    "<a href='http://hank.com' title='PLACEHOLDER'>Hank</a>",
    "<a href='http://marie.com' title='PLACEHOLDER'>Marie</a>",
    "<a href='http://walter.com' title='PLACEHOLDER'>Walter</a>",
    "<a href='http://walter.com' title='PLACEHOLDER'>Walter</a>",
    "<a href='http://jesse.com' title='PLACEHOLDER'>Jesse</a>",
    );

To check how often an equal value is in my array,
I count them with array_count_values.

$count = array_count_values($names);

foreach ($count as $key => $value) {
    echo $value . ' – ' . $key . '<br />';
}

So I get something like this:

3 – <a href='http:/walter.com' title='PLACEHOLDER'>Walter</a>
2 – <a href='http://jesse.com' title='PLACEHOLDER'>Jesse</a>
2 – <a href='http://skyler.com' title='PLACEHOLDER'>Skyler</a>
1 – <a href='http://hank.com' title='PLACEHOLDER'>Hank</a>  
1 – <a href='http://marie.com' title='PLACEHOLDER'>Marie</a>

Now I’d PLACEHOLDER be replaced by $value, so I get the number as title tag of the link.

foreach ($count as $key => $value) {
    echo $value . ' – ' . str_replace('PLACEHOLDER', $value, $key) . '<br />';
}
