1.2.1486. ext/array

Core functions processing arrays.

These functions manipulate arrays in various ways. Arrays are essential for storing, managing, and operating on sets of variables.

This is not a real extension : it is a documentation section, that helps classifying the functions.

<?php
function odd($var)
{
    // returns whether the input integer is odd
    return($var & 1);
}

function even($var)
{
    // returns whether the input integer is even
    return(!($var & 1));
}

$array1 = array('a'=>1, 'b'=>2, 'c'=>3, 'd'=>4, 'e'=>5);
$array2 = array(6, 7, 8, 9, 10, 11, 12);

echo 'Odd :'.PHP_EOL;
print_r(array_filter($array1, 'odd'));
echo 'Even:'.PHP_EOL;
print_r(array_filter($array2, 'even'));
?>
