Remove first and last char from string

问题

I have this:

$dataList = "*one*two*three*";
$list = explode("*", $dataList);
echo"<pre>";print_r($list);echo"</pre>";

which outputs:

> Array (
>     [0] => 
>     [1] => one
>     [2] => two
>     [3] => three
>     [4] =>  )

How do I strip the fist and last * in the string before exploding?

回答1:

Using trim:

trim($dataList, '*');

This will remove all * characters (even if there are more than one!) from the end and the beginning of the string.

回答2:

Some other possibilities:

Using substr:

$dataList = substr($dataList, 1, -1);

You can also choose to not remove the * from the string but rather remove the empty array values which will always be the first and last element. Using array functions array_pop() and array_shift():

$arrData = array_pop(array_shift($arrData));

回答3:

trim($dataList, "*")

回答4:

$string = substr($dataList, 1, -1);

Remove the first and the last character of the string in php

回答5:

echo trim($dataList,"*");

hope this solve your problem
