How To Check If Array Is Empty Or False Value by php help
i want to know if you can help me. i have this code

<?php
$myarray= array();

$myarray[0] = "";
$myarray[1] = false;

if($myarray){
   echo "this is true";
}else{
   echo "this is false";
}
?>


but when i run it, it still comes out true?

when i do this:
PHPCODE:
print_r(array_values($myarray));

it shows me this: Array ( [0] => )

how can i check or verify that an array has a value of zero or false then?

you can do two things:

OPTION 1: USE ISSET() FUNCTION


<?php
$myarray= array();

$myarray[0] = "";
$myarray[1] = false;

if(isset($myarray)){
   echo "this is true";
}else{
   echo "this is false";
}
?>


OPTION 2: USE EMPTY() FUNCTION



<?php
$myarray= array();

$myarray[0] = "";
$myarray[1] = false;

if(empty($myarray)){
   echo "this is true";
}else{
   echo "this is false";
}
?>
