separate variable into sections of 3

[hyster]

I want to separate a number into sections of 3 to make it easier to read

1234567890 into 123 456 789 0. the number is not going to be a set length

 

explode (as far as I can tell) uses a separator to do this IE: ; or - and I carnt find another function to do this

 

thx for any help

Try,

$int = 1234567890; 

$value = chunk_split ( $int , 3, "\n");

echo $value;

EDIT: If you are on windows machine add \r (not sure about that)

$int = 1234567890; 

$value = chunk_split ( $int , 3, "\r\n");

echo $value;

cheers that worked a treat

is there a way to reverse the way the function works? start the count from the right instead of the left?

 

1234 chunk_split = 123 4 // looks a bit daft

1234 chunk_split /reverse = 1 234

Yes, I am a RegEx fan.

im properly being brain dead but I carnt find anything relevant to what im after.

as far as I can tell I can search for specific numbers but not split them the way I want

strlen() and substr() could also be used to do it.

[mac_gyver]

$num = "1234567890";


echo number_format($num,0,'', ' ');

If the value is actually a numeric value, you can use number_format, specifying a space as the thousands separator.

 

If the value is a string of characters limited to the digits 0 - 9, there are a couple of options: 1) Reverse the string, split it, then reverse the result; 2) Pad the string so the length is a multiple of 3, split it, remove the padding.

 

# An actual number
$int = 123456789;
echo number_format($int, 0, '.', ' ');

# A String - Reverse it, split it, reverse the result
$rev = strrev($int);
$split = trim(chunk_split($rev, 3, ' '));
echo strrev($split);

# A String - Extend it, split it, remove padding
$padded = str_repeat('?', 3 - (strlen($int) % 3)) . $int;
$split = chunk_split($padded, 3, ' ');
echo trim(str_replace('?', '', $split));

Of course, there is the brute-force method using a loop to build the output one character at a time, but it's much more code, and I'm too lazy to write it right now.
