[SOLVED] arrays

[gazever]

Hi I was given this code yesterday by effigy,

 

<pre>
<?php
$data = '8,6,9,2,,,7,4,5,3,,,2,1,5,3,4,,,6,9,4,5,3,6,9,8';
$data = str_replace(',,', ', ,', $data);
$array = explode(',', $data);
print_r($array);
?>
</pre>

 

However this string opens from a txt file and replaces the ,, with a space character, I loop through this a few times, incase there are two empty values in a row, producing ,,,     

 

However how would I loop thorugh the array and replace all values that are "" empty to the   value, as if the first value of the array is empty It will not change to a space?

 

I'm sure this is really simple to do.

 

Thanks

if( $data{0} == ',' )
{
  $data = '$nbsp;'.$data;
  print $data;
}

 

Try this. Check character 0, if it is a ',', insert a

thanks, sent me in the right direction, I used this within my existing loop

 

if ($array[$i] == "") {
$array[$i] = " ";
}

if ( strlen( $array[$i] ) == 0) {
$array[$i] = " ";
}

 

would be my prefered solution  ;D ;D ;D (joke)
