Bug description: array_unique function changed
My ISP recently upgraded from 4.0.3pl1 to 4.0.6 - i have a script that runs
an 'array_unique' on a 2d array. This used to work previously, but now it
reduces the array down to a single item.
Here is the section of script:
// CLEAN UP DUPLICATES THAT DON'T HAVE THE DESCRIPTION, BUT ARE THE SAME
SECTION
if ( $debug ) echo "<P
style='text-align:left'><B>CLEAN UP DUPLICATE
SECTIONS</B><BR>
<I>[\$idx,\$count]...</I><BR>";
$count = 0;
for ( $idx = 0; $idx < count($section_result); ++$idx
) {
$comp1 = strtolower($section_result[$idx][0]);
$comp2 =
strtolower($section_result[$idx+1][0]);
$comp3 =
strtolower($section_result[$idx-1][0]);
if ( $comp1 == $comp2 ) {
// IF THIS ENTRY IS THE SAME SECTION AS THE
NEXT ONE
if ( $section_result[$idx+1][1] != ''
) {
$section[$count][0] =
$section_result[$idx+1][0];
$section[$count][1] =
$section_result[$idx+1][1];
++$count;
} elseif ( $section_result[$idx][1] !=
'' ) {
$section[$count][0] =
$section_result[$idx][0];
$section[$count][1] =
$section_result[$idx][1];
++$count;
}
} elseif ( $comp1 != $comp3 ) {
$section[$count][0] =
$section_result[$idx][0];
$section[$count][1] =
$section_result[$idx][1];
++$count;
}
if ( $debug ) echo "[$idx,$count] " .
$section[$count-1][0] . " -- " .
$section[$count-1][1] . "<BR>";
} // close for
if ( $debug ) echo "</P>";
$section = array_unique($section);
if ( $debug ) {
echo "<P style='text-align:left'><B>UNIQUE
SECTIONS AFTER
CLEAN-UP</B><BR>";
echo "section count: " . count($section) . " |
$count<BR>";
echo "<I>Work it thru a 'for' loop:</I><BR>";
for ( $idx = 0; $idx < $count; ++$idx ) {
echo $section[$idx][0] . " -- " .
$section[$idx][1] . "<BR>";
}
echo "<I>Work it thru a 'foreach'
loop:</I><BR>";
foreach ( $section as $message ) {
echo $message[0] . " -- " .
$message[1] . "<BR>";
}
echo "</P>";
echo "<P style='text-align:left'><B>UNIQUE
SECTION_RESULT AFTER
CLEAN-UP</B><BR>";
foreach ( $section_result as $message ) {
echo $message[0] . " -- " .
$message[1] . "<BR>";
}
echo "</P>";
}
