This is the same problem discussed in bug #12848 (which is closed -
could I have reopened it?).
Environment:
FreeBSD 4.7-PRERELEASE #1: Mon Sep 2 12:14:18 IST 2002
Configure Command:
'./configure' '--with-apxs=/usr/local/sbin/apxs'
'--with-config-file-path=/usr/local/etc' '--enable-versioning'
'--with-regex=system' '--without-gd' '--without-mysql'
'--with-mhash=/usr/local' '--with-pgsql=/usr/local'
'--with-ldap=/usr/local' '--enable-xslt'
'--with-xslt-sablot=/usr/local'
'--enable-trans-sid' '--with-expat-dir=/usr/local'
'--with-iconv=/usr/local' '--prefix=/usr/local'
'i386-portbld-freebsd4.7'
(built from FreeBSD ports collection)
Testcase:
<?php
// create an array
$array = array();
for ($i = 1; $i < 25; $i++) {
array_push($array,"Dublin $i");
}
// randomise it
$rand_array = array();
srand ((float) microtime() * 10000000);
foreach (array_rand($array,sizeof($array)) as $index) {
array_push($rand_array,$array[$index]);
}
// get it sorted by string
$array_sorted_str = $rand_array;
sort($array_sorted_str,SORT_STRING);
// get it sorted numerically
$array_sorted_num = $rand_array;
sort($array_sorted_num,SORT_NUMERIC);
echo "Original array";
echo "<ul>";
foreach ($array as $v) {
echo "<li>$v</li>";
}
echo "</ul>";
echo "Randomised array";
echo "<ul>";
foreach ($rand_array as $v) {
echo "<li>$v</li>";
}
echo "</ul>";
echo "array sorted by string";
echo "<ul>";
foreach ($array_sorted_str as $v) {
echo "<li>$v</li>";
}
echo "</ul>";
echo "array sorted numerically";
echo "<ul>";
foreach ($array_sorted_num as $v) {
echo "<li>$v</li>";
}
echo "</ul>";
?>
I would expect the numeric sort to give me Dublin 1, Dublin 2...Dublin
11,Dublin 12...Dublin 20 etc.
While it does change the array, it appears to do so in a random
fashion(at least I cannot understand it).
