php去除右边的逗号的方法:首先创建一个PHP示例文件;然后通过“rtrim($str, ',');”方法删除字符串中右边的逗号即可。
本文操作环境:Windows7系统、PHP7.1版,DELL G3电脑
首先分别解释下,
trim过滤字符串两端,
rtrim过滤字符串尾部,=chop()
ltrim过滤字符串首部.
过滤字符串中键的咚咚就只能用str_replace咯.
举个例子说明下,
PHP代码
代码如下:
$str = '123,333,234,'; echo rtrim($str, ',');
rtrim实例代码2
代码如下:
<?php $text = "\t\tThese are a few words :) ... "; $trimmed = rtrim($text); // $trimmed = "\t\tThese are a few words :) ..." $trimmed = rtrim($text, " \t."); // $trimmed = "\t\tThese are a few words :)" $clean = rtrim($binary, "\x00..\x1F"); // trim the ASCII control characters at the end of $binary // (from 0 to 31 inclusive) ?>
