How to remove null values with PHP?
To remove null value in PHP, use array_filter(). It filters the array values. Let’s say the following is our array −
$studentDetails = array("firstName" => "John", "lastName"=> null);
echo "The original value is=";print_r($studentDetails);Let’s filter with array_filter() −
$result = array_filter($studentDetails);
Example
<!DOCTYPE html>
<html>
<body>
<?php
$studentDetails = array("firstName" => "John", "lastName"=> null);
echo "The original value is=";
print_r($studentDetails);
$result = array_filter($studentDetails);
echo "</br>";
echo "After removing null part,the result is=";
print_r($result);
?>
</body>
</html>Output
The original value is=Array ( [firstName] => John [lastName] => ) After removing null part,the result is=Array ( [firstName] => John )
