How to intercept the string between specified 2 characters in php, intercept the string

The example in this article describes the method of intercepting the string between specified 2 characters in php. Share it with everyone for your reference. The details are as follows:

In php, you only need to determine the stripos position before string 1 and string 2 and then use substr to start intercepting. Here is a simple example.

Usage:

$keyword='查找(计组实验)'
$need=getNeedBetween($keyword, '(' , ')' );

After running the program:

$need='计组实验';

Let’s complete the string interception function getNeedBetween used above. This function can simply intercept the string between two specified characters ($mark1, $mark2) from the string ($kw). If it fails, it returns 0, and if it succeeds, it returns the intercepted string.

<&#63;php
function getNeedBetween($kw1,$mark1,$mark2){
$kw=$kw1;
$kw='123′.$kw.'123′;
$st =stripos($kw,$mark1);
$ed =stripos($kw,$mark2);
if(($st==false||$ed==false)||$st>=$ed)
return 0;
$kw=substr($kw,($st+1),($ed-$st-1));
return $kw;
}
