Description
void
sort ( array array [, int sort_flags])
This function sorts an array. Elements will be arranged from
lowest to highest when this function has completed.
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
See also arsort(),
asort(), ksort(),
natsort(), natcasesort(),
rsort(), usort(),
array_multisort(), and
uksort().
Note:
The second parameter was added in PHP 4.
