Question

I am using a rating system on my site and I call for the value “4_5” in php.

Example:

<span class="rating"><?php echo $meta['rating']; ?></span>

Is there a way I could use this…

$name = str_replace('_', '.', $name);

to replace the underscore after calling for it?

PS. I’m very new at php and html but have searched for this everywhere!

Answer 1

You can’t modify a value in PHP after you echoed it.
But you don’t even need to, because you can use the str_replace around your $meta[‘rating’] like this:

<span class="rating"><?php echo str_replace('_', '.', $meta['rating']); ?></span>

This will display 4_5 as 4.5
