how to make capital letters in php capitalise words
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] => )

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";
}
?>
