<?php
foreach($array as $key=>$value) {
     if ($value=='') {
         unset($array[$key]);
     }
}
?>

Also, if you want to reassign the indexes to their new values, perform this afterwards:

<?php
$array=array_keys($array);
?>

 

EDIT: Just did some googling and found a more simple function. http://us2.php.net/array_filter

<?php
foreach($array as $key=>$value) {
     if ($value=='') {
         unset($array[$key]);
     }
}
?>

thanks for your help

but it didn't work

<?php
$input = array("a", "b", "c", "d", "e");

foreach($array as $key=>$value) {
     if ($value=='d') {
         unset($input[$key]);
     }
}
$input=array_keys($input);
for($i0=0;$i0<count($input);$i0++)

thanks about $input....

but it doesn't work yet.

<?php
$input = array("a", "b", "c", "d", "e");

foreach($input as $key=>$value) {
     if ($value=='d') {
         unset($input[$key]);
     }
}
$input=array_keys($input);
for($i0=0;$i0<count($input);$i0++)
{
echo $input[$i0]." ";// result 0 1 2 4
}
?>
result is 0 1 2 4
and without [i]$input=array_keys($input);[/i] result is a b c

solved

<?php
$input = array("a", "b", "c", "d", "e");

foreach($input as $key=>$value) {
     if ($value=='d') {
         unset($input[$key]);
     }
}
$input=array_values($input);
for($i0=0;$i0<count($input);$i0++)
{
   echo $input[$i0]." ";// result 0 1 2 4
}
?>

I should use array_values($input);
