php根据指定位置和长度获得子字符串的方法,php字符串

本文实例讲述了php根据指定位置和长度获得子字符串的方法。分享给大家供大家参考。具体分析如下:

php的substr函数功能非常强大,不断可以从前往后去子字符串还可以从后往前取字符串

<&#63;php
$string = "beginning";
print("Position counted from left: ".substr($string,0,5)."\n");
print("Position counted form right: ".substr($string,-7,3)."\n");
&#63;>

输出结果:

Position counted from left: begin
Position counted form right: gin

希望本文所述对大家的php程序设计有所帮助。
