I have the array $var, and I'd like to return FALSE if one or more element in the array are empty (I mean, the string are "").

I think that array_filter() is the better way, but I don't know how to filter it in this manner.

How can I do it?

function emptyElementExists()

function emptyElementExists($arr) {
  return array_search("", $arr) !== false;
  }

Example:

$var = array( "text1", "", "text3" );
var_dump( emptyElementExists($var) );

Output:

bool(true)
