Example #2 Using indexed arrays with preg_replace() <?php $string = 'The quick brown fox jumps over the lazy dog.'; $patterns = array(); $patterns[0] = '/quick/'; $patterns[1] = '/brown/'; $patterns[2] = '/fox/'; $replacements = array(); $replacements[2] = 'bear'; $replacements[1] = 'black'; $replacements[0] = 'slow'; echo preg_replace($patterns, $replacements, $string); ?> Example #1 iconv() example <?php $text = "This is the Euro symbol '€'."; echo 'Original : ', $text, PHP_EOL; echo 'TRANSLIT : ', iconv("UTF-8", "ISO-8859-1//TRANSLIT", $text), PHP_EOL; echo 'IGNORE : ', iconv("UTF-8", "ISO-8859-1//IGNORE", $text), PHP_EOL; echo 'Plain : ', iconv("UTF-8", "ISO-8859-1", $text), PHP_EOL; ?>
