Hey all,

I'm in the middle of building a numerology script and it is essential that i can split a string into two variables so i can add the two together to get the answer i need.

Does anyone on here know how to do this??

I've spent nearly all day going through google and can't find anything on how to do it.

I was thinking of putting the string into an array and then splitting it using extract() but i don;t know how that would work??

Regards,

Something like this? http://us2.php.net/preg-split

Do you want to split into two variables like that:
string: Hello world ---> string1=Hello and string2= world ?

You can do it in two ways:
split with delimiter: PHP explode
extract: PHP substr

Will the string have a fixed amount of characters, or will the first of the two variables have a fixed amount of characters?

Well the string should only be between 2 and 4 charecters long.

to give you a better idea if i had a string with 26 in it how would i split it in to two variables one with 2 and one with 6 so i could add the 2 numbers together?

PHP Code:

$var="26";
$first=$var[0];  // $first=2
$second=$var[1];  //  $second=6 


A string is nothing more than an array of character.
You can access anyone of them by using the index. Just remember than an index start from 0, not 1 in PHP

To tag on Tripy's note, you could add the sum of a numeric string:

PHP Code:

$value = '1234';
for ($sum = 0, $i = 0; $i < strlen($value); $i++) if (ereg('[0-9]', $value[$i])) $sum += (int)$value[$i];
echo $sum;  // output is 10 


Again, check this

Thanks everyone for your solutions, i have managed to get it done by using chunk_split and then putting them into an array and using list to extract them into individual vars.
