Better way to replace multiple different words at once in PHP
I've been doing a file_get_contents code for a while now, and I'm getting really tired of using my method to replace multiple different words at once. Sometimes the site I'm file_get_contents from, has changed their layout and therefore has to change up in all this mess. This is the method I'm using: $results = file_get_contents('https://example.com/'); $filter1 = str_replace('https://example.com', 'index.php', $results); $filter2 = str_replace('<script', '<!-- OVERWRITTEN ', $filter1); $filter3 = str_replace('</script>', ' OVERWRITTEN -->', $filter2); $filter4 = str_replace('src="http://example.com', 'src="', $filter3); $output = str_replace('<p>Some Text</p>', '<p>Something Else</p>',$filter4); echo $output; Is it a better and cleaner way of replacing multiple different words at once than I have done? I'm not sure about extra delay that PHP has to handle with such mess
Yep, you can do it by sending in arrays: $results = file_get_contents('https://example.com/'); $output = str_replace( array('https://example.com', '<script', '</script>', 'src="http://example.com', '<p>Some Text</p>'), array('index.php', '<!-- OVERWRITTEN ', ' OVERWRITTEN -->', 'src="', '<p>Something Else</p>'), $results ); echo $output; For clarity, the replace code is: $output = str_replace( array('https://example.com', '<script', '</script>', 'src="http://example.com', '<p>Some Text</p>'), array('index.php', '<!-- OVERWRITTEN ', ' OVERWRITTEN -->', 'src="', '<p>Something Else</p>'), $results );
