How can PHP file system functions be utilized to generate HTML and PHP files for a template system?

To generate HTML and PHP files for a template system using PHP file system functions, you can create a template file with placeholders for dynamic content, read the template file, replace the placeholders with actual content, and then write the modified content to a new HTML or PHP file.

// Define the template file path
$templateFilePath = 'template.html';

// Read the template file
$templateContent = file_get_contents($templateFilePath);

// Replace placeholders with actual content
$dynamicContent = 'Hello, World!';
$finalContent = str_replace('{{content}}', $dynamicContent, $templateContent);

// Define the output file path
$outputFilePath = 'output.html';

// Write the modified content to a new HTML file
file_put_contents($outputFilePath, $finalContent);
