ARRAY_DIFF(3) 1 ARRAY_DIFF(3)
array_diff - Computes the difference of arrays
SYNOPSIS
array array_diff (array $array1, array $array2, [array $...])
DESCRIPTION
Compares $array1 against one or more other arrays and returns the values in $array1 that are not present in any of the other arrays.
PARAMETERS
o $array1
- The array to compare from
o $array2
- An array to compare against
o $...
- More arrays to compare against
RETURN VALUES
Returns an array containing all the entries from $array1 that are not present in any of the other arrays.
EXAMPLES
Example #1
array_diff(3) example
<?php
$array1 = array("a" => "green", "red", "blue", "red");
$array2 = array("b" => "green", "yellow", "red");
$result = array_diff($array1, $array2);
print_r($result);
?>
Multiple occurrences in $array1 are all treated the same way. This will output :
Array
(
[1] => blue
)
NOTES
Note
Two elements are considered equal if and only if (string) $elem1 === (string) $elem2. In words: when the string representation is
the same.
Note
This function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using
array_diff($array1[0], $array2[0]);.
