What are some best practices for working with string functions when reading a template in PHP?

When working with string functions in PHP to read a template, it's important to properly handle variables within the template. One common issue is when trying to replace placeholders with dynamic values. To solve this, you can use functions like `str_replace` or `preg_replace_callback` to substitute variables in the template with actual values. 

$template = "Hello, {{name}}! Today is {{day}}.";

$data = [
    'name' => 'John',
    'day' => 'Monday'
];

foreach ($data as $key => $value) {
    $template = str_replace("{{" . $key . "}}", $value, $template);
}

echo $template;
