php一个解析字符串排列数组的方法,php解析字符串数组
本文实例讲述了php一个解析字符串排列数组的方法。分享给大家供大家参考。具体如下:
<?php $str="1|苹果|30 1|桃子|50 1|普通|10 2|小麦|100 2|玉米|35 2|大米|30 3|电脑|5 3|MP3|121 3|打印机|8"; $strArray=explode("\n",$str); /*关键的是下面的代码*/ $result=array(); foreach($strArray as $item) { $itemArray=explode('|',$item); $result[$itemArray[0]][]=$item; } echo "<pre class="brush:php;toolbar:false">"; print_r($result); echo "<pre class="brush:php;toolbar:false">"; ?>
运行结果如下:
<pre class="brush:php;toolbar:false">Array ( [1] => Array ( [0] => 1|苹果|30 [1] => 1|桃子|50 [2] => 1|普通|10 ) [2] => Array ( [0] => 2|小麦|100 [1] => 2|玉米|35 [2] => 2|大米|30 ) [3] => Array ( [0] => 3|电脑|5 [1] => 3|MP3|121 [2] => 3|打印机|8 ) ) <pre class="brush:php;toolbar:false">
希望本文所述对大家的php程序设计有所帮助。
