How can developers ensure that text replacement in PHP scripts occurs at the correct stage of script execution to avoid issues, as highlighted in the forum thread?

The issue arises when text replacement in PHP scripts occurs before the variables are defined, leading to incorrect output. To solve this problem, developers can ensure that text replacement happens after the variables are initialized and populated with values.

<?php
// Define variables
$name = "John";
$age = 30;

// Perform text replacement after variables are defined
$message = "Hello, my name is {$name} and I am {$age} years old.";
echo $message;
?>
