PHP program code to delete the last character of a string_PHP tutorial

This is the simplest PHP introductory tutorial. We only need to know a few common functions to delete the last character of a string, such as substr, rtrim, etc.

Original string 1,2,3,4,5,6,
Remove the last character "," and the final result is 1,2,3,4,5,6
The code is as follows:

The function that comes with the system can achieve this effect, two methods:

The code is as follows

代码如下	复制代码
$str = "1,2,3,4,5,6,"; $newstr = substr($str,0,strlen($str)-1); echo $newstr;  //echo 1,2,3,4,5,6

Copy code

$str = "1,2,3,4,5,6,";

$newstr = substr($str,0,strlen($str)-1);

echo $newstr; //echo 1,2,3,4,5,6

1) substr($str, 0, -1)

2) rtrim($str, ",") The above example only describes the use of PHP's own functions. We can also use many methods to achieve it. I won't go into details here. You can refer to the most basic PHP introductory tutorial. http://www.bkjia.com/PHPjc/629131.htmlwww.bkjia.com
