本文实例讲述了php字符串按照单词进行反转的方法。分享给大家供大家参考。具体分析如下:

下面的php代码可以将字符串按照单词进行反转输出,实际上市现将字符串按照空格分隔到数组,然后对数组进行反转输出

<&#63;php
$s = "Reversing a string by word";
// break the string up into words
$words = explode(' ',$s);
// reverse the array of words
$words = array_reverse($words);
// rebuild the string
$s = implode(' ',$words);
print $s;
&#63;>
Copy after login

输出结果如下:
word by string a Reversing

希望本文所述对大家的php程序设计有所帮助。
