$template = "Hello, {{name}}! How are you today?"; $replaceArray = array("{{name}}" => "John"); $result = str_replace(array_keys($replaceArray), array_values($replaceArray), $template); echo $result; // Output: Hello, John! How are you today?
$templateFile = "template.html"; $template = file_get_contents($templateFile); $replaceArray = array("{{title}}" => "My Website", "{{description}}" => "This is my website"); $result = str_replace(array_keys($replaceArray), array_values($replaceArray), $template); echo $result;In this example, we have a template HTML file with two placeholders {{title}} and {{description}}. We use the file_get_contents() function to read the file and store its content in a string variable. Then we use the str_replace() function to replace the placeholders with their respective values. Package Library: The PHP Template replace function is a built-in function in PHP, so no external package library is needed.
