getting texto from inside one string

[Anon]

I have a string like

$string = "1[abcd] 2[abcd] 3[.....]";

And I need to get the values inside [] after each number, preferably into an array like:

$array[0][number] = 1
$array[0][value] = "abcd"

$array[1][number] = 2
$array[1][value] = "abcd"

$array[2][number] = 3
$array[2][value] = .....

(etc)

Preferably without heavy string searching [for loop].

Thanks in advance.

Well, there are many ways to solve this. I'd go with something like this;

---

$string = "1[abcd] 2[efgh] 3[ijkl]";

$contents = explode(" ", $string);
// We now have $contents with n[...] in each element

$result = array();
$count = 0;
// itterate through the elements
foreach ($contents AS $key => $val) {
// regexp to filter data
preg_match('/([0-9])[(.)]/', $val, $match);

// assign matches to $result
$result[$count]["number"] = $match[1];
$result[$count]["value"] = $match[2];

// increase counter
$count++;

}

And then, we check the output;

---

foreach ($result AS $k => $v) {
print "$k - num: $v[number], val: $v[value]<br>";

}

Outputs;

0 - num: 1, val: abcd
1 - num: 2, val: efgh
2 - num: 3, val: ijkl

Wich seems good to me 😉

Hope it helped.
