How to intercept the string between specified 2 characters in php

In php, you only need to determine the stripos position before string 1 and string 2 and then use substr to start intercepting That’s it, here’s a simple example for you.

Usage:

1 2	$keyword='查找(计组实验)' $need=getNeedBetween($keyword, '(' , ')' );

1 2

$keyword='Search (group experiment)'

$need=getNeedBetween($keyword, '(' , ')' );

1	$need='计组实验';

After running the program:

1 2 3 4 5 6 7 8 9 10 11 12

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; } ?>

1

$need='Group experiment';

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.

1 2 3 4 5 6 7 8 9 10 11 12

<🎜>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; } ?>
