$first = "abcdefg";
$second = "aeg";
 
echo similar_text($first, $second);结果输出3.如果想以百分比显示，则可使用它的第三个参数,如下：

$first = "abcdefg";
$second = "aeg";
 
similar_text($first, $second, $percent);
echo $percent;

<?php
    echo levenshtein("Hello World","ello World");
    echo "<br />";
    echo levenshtein("Hello World","ello World",10,20,30);
?>

echo date(‘Y-m-d H:i:s’, time()); 输出为：2007-03-14 12:15:27

echo gmdate(‘Y-m-d H:i:s’, time()); 输出为：2007-03-14 04:15:27

<?php
echo date("M d Y H:i:s", mktime (0,0,0,1,1,2000));
echo gmdate("M d Y H:i:s", mktime (0,0,0,1,1,2000));
?>

输出：
