How to remove empty values from an array in PHP
Topic: PHP / MySQLPrev|Next
Answer: Use the PHP array_filter() function
You can use the PHP array_filter() function to remove or filter empty or false values from an array. This function typically filters the values of an array using a callback function, however if no callback function is specified, all the values of the array which are equal to FALSE will be removed, such as an empty string or a NULL value. Let's take a look at an example:
Example
Try this code »$array = array("apple", "", 2, null, -5, "orange", 10, false, "");
var_dump($array);
echo "<br>";
// Filtering the array$result = array_filter($array);
var_dump($result);
