string between, php

Question

as I am new to php, and after googling :) I still could not find what I wanted to do.

I have been able to find start and end position in string that i want to extract but most of the example use strings or characters or integers to get string between but I could not find string bewteen two positions.

For example: $string = "This is a test trying to extract"; $pos1 = 9; $pos2 = 14;

Then I get lost. I need to get the text between position 9 and 14 of of the string. Thanks.

Answer 1

$startIndex = min($pos1, $pos2);
$length = abs($pos1 - $pos2);

$between = substr($string, $startIndex, $length);

Answer 2

You can use substr() to extract part of a string. This works by setting the starting point and the length of what you want to extract.

So in your case this would be:

$string = substr($string,9,5); /* 5 comes from 14-9 */
