Get two words (numbers) around a certain text in a string - php

Question

There's a certain contents (from a webpage) where I need to get two numbers of a certain list.
Basically the list goes like:
..... 10 from 12....
..... 1 from 20....
..... 20 from 100...
and so on. For me, I need to get these numbers surrounding the word "from", so I can perform certain calculations with them later.
I looked into this and tried different ways to perform it with strpos or strstr but nothing worked. Does anyone have any idea how to accomplish something like that?

Answer 1

$text = "..... 10 from 12 etc....
..... 1 from 20....
..... 20 from 100...";
$r = preg_match_all('~(\d+) *from *(\d+)~u',$text,$match, PREG_SET_ORDER);
var_export($match);
Output:
array (
0 =>
array (
0 => '10 from 12',
1 => '10',
2 => '12',
),
1 =>
array (
0 => '1 from 20',
1 => '1',
2 => '20',
),
2 =>
array (
0 => '20 from 100',
1 => '20',
2 => '100',
),
)
Explanations:
\d+ one digit or more
(\d+) the sequence in brackets -> the digits in the result array
* no, one or more spaces
from the word from

Answer 2

Here is an example of what you can do with explode:
<?php
/* the text with many different gaps and mess! */
$text = "wlfsdjf;sd sdfljsdfk kfgjdlg d 10 from 200 kflgjdkgdklgsd slfksjd
dfgdf fgdlkjdf d 20 from 30 ldk;lfsd
dflksdjf 40 from 50 dkf;sd sdjfs ";
/* main array */
$array = explode("\n",$text);
echo '<pre>';
print_r($array);
/* looping and clearing out our values per line */
foreach($array as $k => $line){
$f = explode(" ",explode(" from ",$line)[0]);
$f = array_pop($f);
$numbers[$k]['first'] = $f;
$s = explode(" ",explode(" from ",$line)[1]);
$s = $s[0];
$numbers[$k]['second'] = $s;
}
/* our new array set per line */
print_r($numbers);
Will return:
Array
(
[0] => wlfsdjf;sd sdfljsdfk kfgjdlg d 10 from 200 kflgjdkgdklgsd slfksjd
[1] => dfgdf fgdlkjdf d 20 from 30 ldk;lfsd
[2] => dflksdjf 40 from 50 dkf;sd sdjfs
)
Array
(
[0] => Array
(
[first] => 10
[second] => 200
)
[1] => Array
(
[first] => 20
[second] => 30
)
[2] => Array
(
[first] => 40
[second] => 50
)
)
