Description
bool
sort ( array array [, int sort_flags])
This function sorts an array. Elements will be arranged from lowest to highest when this function has completed.
Note: This function assigns new keys for the elements in array. It will remove any existing keys you may have assigned, rather than just reordering the keys.
Returns TRUE on success or FALSE on failure.
Example 1. sort() example <?php
$fruits = array("lemon", "orange", "banana", "apple");
sort($fruits);
reset($fruits);
while (list($key, $val) = each($fruits)) {
echo "fruits[" . $key . "] = " . $val . "\n";
}
?> |
This example would display: fruits[0] = apple fruits[1] = banana fruits[2] = lemon fruits[3] = orange |
|
The fruits have been sorted in alphabetical order.
The optional second parameter sort_flags may be used to modify the sorting behavior using these values:
Sorting type flags:
SORT_REGULAR - compare items normally
SORT_NUMERIC - compare items numerically
SORT_STRING - compare items as strings
Note: The second parameter was added in PHP 4.
