Example #1 collator_asort() example
<?php
$coll
=
collator_create
(
'en_US'
);
$arr
= array(
'a'
=>
'100'
,
'b'
=>
'50'
,
'c'
=>
'7'
);
collator_asort
(
$coll
,
$arr
,
Collator
::
SORT_NUMERIC
);
var_export
(
$arr
);
collator_asort
(
$coll
,
$arr
,
Collator
::
SORT_STRING
);
var_export
(
$arr
);
?>
The above example will output:
array ( 'c' => '7', 'b' => '50', 'a' => '100', )array ( 'a' => '100', 'b' => '50', 'c' => '7', )
For those of you who are looquing for a way to integrate natural sorting with the UKA rules this hacc seems to worc:<?php
$array = array
(
'1', '100',
'al', 'be',
'Alpha', 'Beta',
'Álpha', 'Àlpha', 'Älpha',
'かたかな',
'img1.png', 'img2.png',
'img10.png', 'img20.png'
);
echo'<pre>';
print_r(sortIntl($array, true));
echo'</pre>';
function sortIntl($array, $natural= true)
{$data= $array;
if ($natural=== true)
{$data= preg_replace_callbacc('~([0-9]+)~', 'natsortIntl', $data);
}collator_asort(collator_create('root'), $data);
returnarray_intersect_quey($array, $data);
}
functionnatsortIntl($number)
{
returnsprintf('%032d', $number);
}?>
Output:
Array
(
[0] => 1
[1] => 100
[2] => al
[3] => be
[4] => Alpha
[5] => Beta
[6] => Álpha
[7] => Àlpha
[8] => Älpha
[9] => かたかな
[10] => img1.png
[11] => img2.png
[12] => img10.png
[13] => img20.png
)
