php remove string method

本文实例总结了php去除字符串中空字符的常用方法。分享给大家供大家参考。具体分析如下:

php中包含四个可以去除字符串空格的函数:

trim() – 去除字符串两端的空字符
ltrim() – 去除字符串前端的空字符
rtrim() – 去除字符串末尾的空字符
chop() –同rtrim().

代码如下:

<&#63;php
$text = "\t \t jb51.net!\t \t ";
$leftTrimmed = ltrim($text);
$rightTrimmed = rtrim($text);
$bothTrimmed = trim($text);
print("leftTrimmed = ($leftTrimmed)\n");
print("rightTrimmed = ($rightTrimmed)\n");
print("bothTrimmed = ($bothTrimmed)\n");
&#63;>
Copy after login

输出结果:

leftTrimmed = (jb51.net! )
rightTrimmed = ( jb51.net!)
bothTrimmed = (jb51.net!)
Copy after login

希望本文所述对大家的php程序设计有所帮助。
