Convert a phone number

oscar2

Hi,

how can I convert an 8-number phone number like: 12345678 to: 123 456 78 ??

Thank you,
Michel

substr() maybe?

<?php
$3part=substr("12345678", 1, 3);
$2part=substr("12345678", 3, 3);
$1part=substr("12345678", -2);
?>

I tried this, with output:
Phone number: <?php echo $1part ;?> <?php echo $2part ;?> <?php echo $3part ;?>

But it gives an error..
and.. the phone number is given in a variable from a previous page. variable is called "phonenr", how do I replace that for where now 12345678 is written?

thanx in advance.

But it gives an error..

As it should, since variable names can't begin with numerals. Switch the names around ($part1, ...) and it will be ok.

I wrote a little function that also works with numbers of other lengths than 8:

<?php

function telephonize($number)
{
$return = array();
for ($i=0; $i<strlen($number); $i+=3)
{

In most cases, add the next 3 digits.

if (strlen($number)-$i != 4)
{
$return[] = substr($number, $i, 3);
}

If there are only four digits left, split them in 2&2 instead of 3&1.

Break out of the loop.

else
{
$return[] = substr($number, $i, 2);
$return[] = substr($number, $i+2, 2);
break;
}
}

# Turn the array elements into a string.
$return = implode(' ', $return);

return $return;

}

Examples:

echo telephonize(12345)." ";
echo telephonize(123456)." ";
echo telephonize(1234567)." ";
echo telephonize(12345678)." ";
echo telephonize(123456789)." ";

Thank you all very much, thanks for all the replies. I did it with the following code, as given by Vincent en Kirk Parker;

<?php
$part3=substr($nr06, 0, 3);
$part2=substr($nr06, 3, 3);
$part1=substr($nr06, -2);
?>

<?php echo $part3 ;?> <?php echo $part2 ;?> <?php echo $part1 ;?>

Could it be shorter.. hehe,
okay thanks again people for helping me out!!

Hmm, you must be wearing out the <? keys on your keyboard! :-)

Why not just say:

<?php echo "$part3 $part2 $part1"; ?>

..it's possible.. 🙂

thanks for your reply again, will change it!
