[SOLVED] Parse string from the middle of a string

[refiking]

I need to delete everything before $section1 and everything after $section2.

 

So,

//IF $string = "12345"
$section1 = 12;
$section2 = 4;
//$newstring should return 35

You mean delete everything before or after (like you said) Or delete everything within those 2 variables, like you demonstrated?

 

$string = "12345"
$section1 = 12;
$section2 = 4;
$newstring = str_replace(Array($section1, $section2), NULL, $string);
echo $newstring; // 35

Sorry. Value should be 3 not 35.

<?php
$string = "012333456";
$section1 = '12';
$section2 = '4';
$start = strpos($string,$section1)+strlen($section1);
$end = strpos($string,$section2,$start);
$newstring = substr($string,$start,$end-$start);
echo $newstring; // 3

Nevermind...

 

Forgot to change the $string variable

that means $section1 wasn't found in the string. did you make sure and use quotes around your $string, $section1, and $section2 values?
