A simple example of splitting Chinese strings into arrays in PHP

In PHP, splitting a string is very simple, mainly using the function preg_match_all. When processing strings containing Chinese characters, you can use the following method:

<?php
    $str = "hi123是中国的";
    preg_match_all("/./u", $str, $arr);
    print_r($arr[0]);
    //by bbs.it-home.org
?>

Output result: Array ( [0] => h [1] => i [2] => fishing [3] => fish [4] => Island [5] => Yes [6] => Medium [7] => Country [8] => )

Note: The mode modifier u is fully supported in php5.

Example 2, split Chinese string with PHP

Split the string "爱伦说" into single words of "爱", "Lotus", and "说".

Use the php function preg_match_all. Example:

<?php
$str = "爱莲说";
preg_match_all('/[\x{4e00}-\x{9fa5}]/u',$str,$string);
dump($string);
//by bbs.it-home.org
?>

Output result: array 0=> array 0 =>string 'love'(length=3) 1 =>string'Lian'(length=3) 2 =>string 'say'(length=3) At this time, to obtain a specific word, you can obtain it through the array.
