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:
1
2
3
4
5
6

<?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" );
?>
|
输出结果:
1
2

leftTrimmed = (jb51.net! )
rightTrimmed = ( jb51.net!)
bothTrimmed = (jb51.net!)
