how do I replace something from a output of PHP function?

Question

I am trying make some changes in a php code -

Below line

<meta itemprop="price" content="<?php echo $special; ?>"/>

shows up like this in HTML

<meta itemprop="price" content="£32.12"/>

I need to remove this Pound("£") sign from the output. How can I use replace function in this code or there is some other way to do it.

Can someone advise?

tried this - <meta itemprop="price content="<?php echo str_replace($special, '£','') ?>"/> it's not printing anything in this case. — Sanchit

Use this:

<?php
//  REMOVES ONLY BRITISH CURRENCY: £ 
<meta itemprop="price" content="<?php echo str_replace('£', '', $special); ?>"/>

OR this:

//  REMOVES CURRENCIES LIKE £, $ & € 
<meta itemprop="price" content="<?php echo preg_replace('&(£|$|€)&', '', $special); ?>"/>

Use str_replace

<?php
$special = str_replace("£", "", $special);
?>
<meta itemprop="price" content="<?php=$special;?>"/>

If you need to replace multiple currencies, you can use an array, i.e.:

<?php
$remove = array("£", "€", "$", "₹", "¥", "¢");
$special = str_replace($remove, "", $special);
?>
<meta itemprop="price" content="<?php=$special;?>"/>
