Hi,
When using sort on an associative array:
foreach $key (sort(keys(%opalfabet))){
$value = $opalfabet{$key};
$result .= $value;
}
How does it handle double values?
It seems to me that it removes them, is that true? If so, is there a way to get... (2 Replies)

Generalized arrays take any type of variable(s) as subscripts, but the subscript(s) are treated as one long string expression.
The use of for(a in x) on a generalized array will return all of the valid subscripts in some order, not necessarily the one you wished.
How can I make it so that i... (2 Replies)

I would like to do the following sorting, but the output is not what i expected. Why 222 and 2222 are not at the last two elements of array?

sort
SORT(3) 1 SORT(3)sort - Sort an arraySYNOPSIS
bool sort (array &$array, [int $sort_flags = SORT_REGULAR])
DESCRIPTION
This function sorts an array. Elements will be arranged from lowest to highest when this function has completed.
PARAMETERS
o $array
- The input array.
o $sort_flags
- The optional second parameter $sort_flags may be used to modify the sorting behavior using these values: Sorting type flags:
o SORT_REGULAR - compare items normally (don't change types)
o SORT_NUMERIC - compare items numerically
o SORT_STRING - compare items as strings
o SORT_LOCALE_STRING - compare items as strings, based on the current locale. It uses the locale, which can be changed using
setlocale(3)
o SORT_NATURAL - compare items as strings using "natural ordering" like natsort(3)
o SORT_FLAG_CASE - can be combined (bitwise OR) with SORT_STRING or SORT_NATURAL to sort strings case-insensitively
RETURN VALUES
Returns TRUE on success or FALSE on failure.
CHANGELOG
+--------+---------------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| 5.4.0 | |
| | |
| | Added support for SORT_NATURAL and |

EXAMPLES
Example #1
sort(3) example
<?php
$fruits = array("lemon", "orange", "banana", "apple");
sort($fruits);
foreach ($fruits as $key => $val) {
echo "fruits[" . $key . "] = " . $val . "
";
}
?>
The above example will output:
fruits[0] = apple
fruits[1] = banana
fruits[2] = lemon
fruits[3] = orange
The fruits have been sorted in alphabetical order.
Example #2
sort(3) example using case-insensitive natural ordering
<?php
$fruits = array(
"Orange1", "orange2", "Orange3", "orange20"
);
sort($fruits, SORT_NATURAL | SORT_FLAG_CASE);
foreach ($fruits as $key => $val) {
echo "fruits[" . $key . "] = " . $val . "
";
}
?>
The above example will output:
fruits[0] = Orange1
fruits[1] = orange2
fruits[2] = Orange3
fruits[3] = orange20
The fruits have been sorted like natcasesort(3).
NOTES
Note
This function assigns new keys to the elements in $array. It will remove any existing keys that may have been assigned, rather than
just reordering the keys.
Note
Like most PHP sorting functions, sort(3) uses an implementation of Quicksort. The pivot is chosen in the middle of the partition
resulting in an optimal time for already sorted arrays. This is however an implementation detail you shouldn't rely on.
Warning
Be careful when sorting arrays with mixed types values because sort(3) can produce unpredictable results.
