爆炸成相等的部分

问题描述

|

$str =  \"Hello fri3nd,you\'re looking good today!  What a Great day this is!  How     fancy and cool!\";
$pieces = explode(\" \",$str,3);

print_r($pieces);

所以这给了我

$pieces[0] = \'Hello\',

$ pieces [1] = \'fri3nd \'

... and the rest of the string is all shoved into

$ pieces [3]`。如何每3或4个字爆炸一次？     

解决方法

        也许：？

<?php
$str =  \"Hello fri3nd,you\'re looking good today!  What a Great day this is!  How     fancy and cool!\";

$array = array_map(create_function(\'$a\',\'return implode(\" \",$a);\'),array_chunk(preg_split(\'/\\s+/\',$str),3));
var_dump($array);

说明： 首先，您在任意（组合）空白处分割字符串：

preg_split

然后“分割”结果数组：the5ѭ 然后您将

implode

用

array_map

应用于任何结果的单词组     ,        使用php

str_split

函数：-

$pieces = str_split( $str,3);
