php去除字符串中空字符的方法有哪些?

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().
Copy after login

代码如下:

<?php
$text = "\t \t bitsCN.com!\t \t ";
$leftTrimmed = ltrim($text);
$rightTrimmed = rtrim($text);
$bothTrimmed = trim($text);
print("leftTrimmed = ($leftTrimmed)\n");
print("rightTrimmed = ($rightTrimmed)\n");
print("bothTrimmed = ($bothTrimmed)\n");
?>
Copy after login

输出结果:

leftTrimmed = (bitsCN.com! )
rightTrimmed = ( bitsCN.com!)
bothTrimmed = (bitsCN.com!)
Copy after login
