sort
(PHP 4, PHP 5)
sort — Sort an array
Description
This function sorts an array. Elements will be arranged from lowest to highest when this function has completed.
Notă: Această funcţie atribuie chei noi elementelor din array . Ea va elimina cheile existente, pe care posibil le-aţi atribuit, în loc doar să rearanjeze cheile.
Întoarce valoarea TRUE în cazul succesului sau FALSE în cazul eşecului.
Example#1 sort() example
<?php
$fruits = array("lemon", "orange", "banana", "apple");
sort($fruits);
foreach ($fruits as $key => $val) {
echo "fruits[" . $key . "] = " . $val . "\n";
}
?>
Exemplul de mai sus va afişa:
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 (don't change types)
- SORT_NUMERIC - compare items numerically
- SORT_STRING - compare items as strings
- SORT_LOCALE_STRING - compare items as strings, based on the current locale. Added in PHP 4.4.0 and 5.0.2. Before PHP 6, it uses the system locale, which can be changed using setlocale(). Since PHP 6, you must use the i18n_loc_set_default() function.
Notă: The second parameter was added in PHP 4.
Be careful when sorting arrays with mixed types values because sort() can produce unpredictable results.
