[Resolved] Array values question.

[n00854180t]

What do you use if you wanted to check if any of the values of an array are empty?

Like this?

<?php

if($_POST[] == ""){

   echo "Array is empty.";

} else {

   echo "Array is NOT empty";

}

?>

look up the php manual.

foreach / list are what u need to read about. Their are examples provided their on the manual

www.php.net

Actually neither of those functions really do what I want. I want to test whether or not any or all of the values of the $_POST array are null.

[shavas]

while($temp=key($_POST)){

 $temp2=str_replace('^^','"',$$temp);
 $_POST[$temp]=$temp2;
 $$temp=$temp2;
 next($_POST);
 }

foreach ($_POST as $value) {
if($value== ""){

echo "Array is empty.";

} else {

echo "Array is NOT empty";

}

}

Their are DOZENS of examples that do what you want on the php.net page. ie the first two on the page. simple place your condition in the loops like my above examples

You may have noticed that the following are functionally identical:

<?php
$arr = array("one", "two", "three");
reset ($arr);
while (list(, $value) = each ($arr)) {
echo "Value: $value<br>\n";
}

foreach ($arr as $value) {
echo "Value: $value<br>\n";
}
?>

The following are also functionally identical:

<?php
reset ($arr);
while (list($key, $value) = each ($arr)) {
echo "Key: $key; Value: $value<br>\n";
}

foreach ($arr as $key => $value) {
echo "Key: $key; Value: $value<br>\n";
}
?>

Do you want to see if ANY value of a given array is a zero length string? Then this should work:

$vals = array_values($array_name);

if (in_array("",$vals)) print "array has an empty value";
