Split Number Into Different Characters

[Dragosvr92]

I am looking into splitting a number of this format "1234567890024" in an array

that would look like this:

 

Array
(
[0] => 1
[1] => 23
[2] => 45
[3] => 67
[4] => 89
[5] => 002
[6] => 4
)

 

I had a look at str_split, but it doesnt seem to allow you to split a number in different numbers..

Assuming the number is always the same length and format, you can use regex. Below is one example:

 

<?php
$input = '1234567890024';
preg_match('/([0-9]{1})([0-9]{2})([0-9]{2})([0-9]{2})([0-9]{2})([0-9]{3})([0-9]{1})/', $input, $match);
if (isset($match[0]) && $match[0] == $input) unset($match[0]);
print_r($match);

A bit cleaner version, as you only need to use \d to check for digits.

<?php
$input = '1234567890024';
preg_match('/(\\d)(\\d{2})(\\d{2})(\\d{2})(\\d{2})(\\d{3})(\\d)/', $input, $match);
if (isset($match[0])) {
   // If index 0 is set it will always match the entire RegExp.
   unset($match[0]);
}
print_r($match);

Thank you both. I will go for the cleaner version's preg match, and use the shorter if statement.

Is there any documentation of the preg_match things used to split something? I dont know how they work at all.

 

Also, do you know how may i replace $match[5] aka 89 with a word that is found inside another array of words?

The word inside the array would have the number 89.

 

Should i use an if statement, or some str/preg_replace ....?

[Christian F.]

The PHP manual contains all the information you need about the different PHP functions.

 

As for your second question: If that word has the index "89" in the array, then it's just to use $match[5] to reference it. Like this:

$letter = $letterArray[$match[5]];

You can even use the same method to overwrite the match, by simply substituting the new variable with $match[5].

I dont understand....

 

So i have this array :

 

Array
(
[1] => 1
[2] => 23
[3] => 45
[4] => 67
[5] => 89
[6] => 002
[7] => 4
)

I need to make an array for each index, and output the matching data.

 

If [1] outputs 1, then it should replace 1 with male, and 2 with female.

I would prefer to do this from an array of :

Array(
[1] => Male
[2] => Female
)

 

 

Something like:

<?php
$gender = $match[1];
if($gender == "1"){echo"Male";}else{echo"Female";}
?>

 

Do i make any sense?

There are many ways to do this, however based on the above example, it would be the following:

 

<?php
$input = '1234567890024';
preg_match('/(\\d)(\\d{2})(\\d{2})(\\d{2})(\\d{2})(\\d{3})(\\d)/', $input, $match);
if (isset($match[0])) {
       // If index 0 is set it will always match the entire RegExp.
       unset($match[0]);
}

$genderArr = array(
   1 => 'Male',
   2 => 'Female'
);

if (isset($genderArr[$match[1]])) echo $genderArr[$match[1]];
var_dump($match);

Why in the world are you doing this?

[Barand]

"sans regex" method

 

<?php
$n = '1234567890024';
$arr = sscanf($n,'%01s%02s%02s%02s%02s%03s%01s');
echo '<pre>'.print_r($arr, 1).'</pre>';
?>

 

result

Array
(
   [0] => 1
   [1] => 23
   [2] => 45
   [3] => 67
   [4] => 89
   [5] => 002
   [6] => 4
)

[Dragosvr92]

Because that long number means something, and i need to extract the data in it.

 

Thank you spfoonnewb.

[Jessica]

Well duh.

Why would you store data in a format like that is the question?

[Dragosvr92]

Well duh.

Why would you store data in a format like that is the question?

Because that number is in an Romanian Social Security Number format, and i wanted to extract all the data out of it, for personal use. I finished the script when i got the Age script from the previous topic i posted in.

Is this solved yet?

[Dragosvr92]

Yes, it is solved. I wasnt used with the new forum software, and havent noticed the solved button.
