php语法如何替换数组中的字符串

如何利用php语法替换数组中的字符串，下面web建站小编给大家简单介绍一下如何利用preg_replace()函数和数组实现字符串替换!

语法如下：

$originalArray = array("123-45-6789", "987-65-4321");
$pattern = array("/(\d{3})-(\d{2})-(\d{4})/", "/(\d{3})-(\d{2})-(\d{4})/");
$replacement = array("$1.$2.$3", "$1-$2-$3");
$replacedArray = preg_replace($pattern, $replacement, $originalArray);
print_r($replacedArray);
