Remove empty array value

[squiblo]

Is there a built in function to remove empty array values for example:

 

change

Array (
    [0] => Bob
    [1] =>
    [2] => Ryan
    [3] => Jane
)

to

Array (
    [0] => Bob
    [1] => Ryan
    [2] => Jane
)

 

Thanks

Hello Squiblo, try the following.

 

$array = array_filter($yourArray);

 

Hopefully that will help you

 

Thanks, Paul.

The problem is that array_filter(), on its own, will remove a legitimate array element if it contains a value that equates to FALSE, such as a zero.

[PaulRyan]

By his example I was going by an array of names which usually doesn't have anything equating to FALSE.

 

The following will work and remove any values that are not set, but keep values like ZERO.

 

<?PHP
// This is your starting array
$oldArray = array('Bob','2','Ryan','Jane','0','false','');

//Initialize a new array to add elements too
$newArray = array();

// Loop through original array to filter out empty elements
foreach($oldArray as $arrayElement) {
  if(isset($arrayElement)) {
    // Only add elements that have content
    array_push($newArray,$arrayElement);
  }
}

print_r($newArray);

?>

 

The above should do the trick.

 

Regards, Paul.

That won't work either. You're looping through an array's values, so all of the values will be set, so nothing will ever be removed. Instead you can do it like this:

 

$arr = array('Bob','2','Ryan','Jane','0','false','');
foreach($arr as $key => $val) {
if($val === '') {
	unset($arr[$key]);
}
}
print_r($arr);

Ahh right yeah, my bad.

Sorry if I caused you any confusion squiblo
