help with arrays

Hey people.

I've got an array like this:


[0] => Array
(
[0] => j
[fname] => j
[1] => j
[lname] => j
[2] => jj
[state] => jj
[3] => j@domain.com
[email] => j@domain.com
[4] => 0
[newsletter] => 0
)

Some cells might be empty so i want to replace every empty cell with
" ". I can easily do this with just the numerical index but I can't
figure out how to do the textual indices also.

Someone have a clue?


Thanks,
Chris.

It doesn't get much simpler :)

foreach( $data as $key => $value )
{
if( $value == '' )
{
$data[$key] = ' '
}
}

Cheers,
Rob.

Of course, you could do it in a much more cryptic way... just for fun.

:-)

INPUT:

<?php

$a = array( '0' => 'j',
'fname' => 'j',
'1' => 'j',
'lname' => 'j',
'2' => 'jj',
'state' => '',
'3' => 'j@domain.com',
'email' => 'j@domain.com',
'4' => '0',
'newsletter' => '0',
);

array_walk($a, create_function('&$v', '$v = ($v=="")?"&nbsp;":$v;'));
print_r($a);

?>

OUTPUT:

petej@computer$ php -f test.php
Array
(
[0] => j
[fname] => j
[1] => j
[lname] => j
[2] => jj
[state] => &nbsp;
[3] => j@domain.com
[email] => j@domain.com
[4] => 0
[newsletter] => 0
)
