chop()
方法chop()函数是PHP中的字符串函数,用于从字符串末尾删除空格或/和指定的字符/字符串。
语法:
chop(string, [char/string]) : string
这里,
字符串是主字符串。
char / string是可选参数,如果指定要从字符串末尾删除的单个字符或一组字符。如果我们不指定字符/字符串,它将删除空格。
例子:
Input: str = "IncludeHelp.com#" char/string to remove "#" Output: "IncludeHelp.com" Input: str = "IncludeHelp.com#" char/string to remove "com#" Output: "IncludeHelp." Input: str = "IncludeHelp.com#" char/string to remove ".com#" Output: "IncludeHelp"
PHP代码:
<?php $str = "IncludeHelp.com#"; //removing "#" echo (chop($str, "#")."\n"); //removing "com#" echo (chop($str, "com#")."\n"); //removing ".com#" echo (chop($str, ".com#")."\n"); ?>
输出结果
IncludeHelp.com IncludeHelp. IncludeHelp
