PHPchop()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
