How can CSS files and scripts be optimized to prevent memory-related errors in PHP applications, especially in Internet Explorer?

To prevent memory-related errors in PHP applications, especially in Internet Explorer, CSS files and scripts can be optimized by minifying them. Minification reduces the file size by removing unnecessary characters such as white spaces, comments, and line breaks, which can help improve loading times and reduce memory usage. 

// Example of minifying CSS file using PHP
$css = file_get_contents('styles.css');
$css = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $css);
$css = str_replace(array("\r\n", "\r", "\n", "\t", '  ', '    ', '    '), '', $css);
file_put_contents('styles.min.css', $css);

// Example of minifying JavaScript file using PHP
$js = file_get_contents('script.js');
$js = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $js);
$js = str_replace(array("\r\n", "\r", "\n", "\t", '  ', '    ', '    '), '', $js);
file_put_contents('script.min.js', $js);
