How can placeholders within an array be replaced with text in PHP?

To replace placeholders within an array with text in PHP, you can use the str_replace function to search for the placeholders and replace them with the desired text. You need to loop through the array and apply the str_replace function to each element that contains the placeholder. This allows you to dynamically replace placeholders with text in an array. 

<?php
$array = ['Hello, {name}!', 'Welcome, {name}!'];
$placeholder = '{name}';
$replacement = 'John';

foreach ($array as $key => $value) {
    $array[$key] = str_replace($placeholder, $replacement, $value);
}

print_r($array);
?>
