Hi Im supposed to compare lines in a file :
KB0005 1019 T IFVATVPVI 0.691 PKC YES
KB0005 1036 T YFLQTSQQL 0.785 PKC YES
KB0005 1037 S FLQTSQQLK 0.585 DNAPK YES
KB0005 1045 S KQLESEGRS 0.669 PKC YES
KB0005 1045 S KQLESEGRS 0.880 unsp YES
KB204320 1019 T IFVATVPVI 0.699 PKC YES
KB204320 1036 T YFLQTSQQL 0.789 PKC YES
KB204320 1037 S FLQTSQQLK 0.589 DNAPK YES
KB204320 1045 S KQLESEGRS 0.880 unsp YES
and print the lines that differs or dont repeat, which i managed to do by first putting lines into 2 arrays (the lines differ in names KB0005 and KB204320) and then by writing a perl script:
OUTPUT:
1019 T IFVATVPVI 0.691 PKC
1019 T IFVATVPVI 0.699 PKC
1036 T YFLQTSQQL 0.785 PKC
1036 T YFLQTSQQL 0.789 PKC
1037 S FLQTSQQLK 0.585 DNAPK
1037 S FLQTSQQLK 0.589 DNAPK
1045 S KQLESEGRS 0.669 PKC
This works good, I just want to print from which line (KB005 or the other) a given line comes from..
Anybody's willing to help?
Thx

Hello,
Let's say that we have the two following arrays

usort
USORT(3) 1 USORT(3)usort - Sort an array by values using a user-defined comparison functionSYNOPSIS
bool usort (array &$array, callable $value_compare_func)
DESCRIPTION
This function will sort an array by its values using a user-supplied comparison function. If the array you wish to sort needs to be sorted
by some non-trivial criteria, you should use this function.
Note
If two members compare as equal, their relative order in the sorted array is undefined.
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.
PARAMETERS
o $array
- The input array.
o $value_compare_func
- The comparison function must return an integer less than, equal to, or greater than zero if the first argument is considered to
be respectively less than, equal to, or greater than the second.
int callback (mixed $a, mixed $b)
Caution
Returning non-integer values from the comparison function, such as float, will result in an internal cast to integer of the
callback's return value. So values such as 0.99 and 0.1 will both be cast to an integer value of 0, which will compare such
values as equal.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
usort(3) example
<?php
function cmp($a, $b)
{
if ($a == $b) {
return 0;
}
return ($a < $b) ? -1 : 1;
}
$a = array(3, 2, 5, 6, 1);
usort($a, "cmp");
foreach ($a as $key => $value) {
echo "$key: $value
";
}
?>
The above example will output:
0: 1
1: 2
2: 3
3: 5
4: 6
Note
Obviously in this trivial case the sort(3) function would be more appropriate.
Example #2
usort(3) example using multi-dimensional array
<?php
function cmp($a, $b)
{
return strcmp($a["fruit"], $b["fruit"]);
}
$fruits[0]["fruit"] = "lemons";
$fruits[1]["fruit"] = "apples";
$fruits[2]["fruit"] = "grapes";
usort($fruits, "cmp");
while (list($key, $value) = each($fruits)) {
echo "$fruits[$key]: " . $value["fruit"] . "
";
}
?>
When sorting a multi-dimensional array, $a and $b contain references to the first index of the array.
The above example will output:
$fruits[0]: apples
$fruits[1]: grapes
$fruits[2]: lemons
Example #3
usort(3) example using a member function of an object
<?php
class TestObj {
var $name;
function TestObj($name)
{
$this->name = $name;
}
/* This is the static comparing function: */
static function cmp_obj($a, $b)
{
$al = strtolower($a->name);
$bl = strtolower($b->name);
if ($al == $bl) {
return 0;
}
return ($al > $bl) ? +1 : -1;
}
}
$a[] = new TestObj("c");
$a[] = new TestObj("b");
$a[] = new TestObj("d");
usort($a, array("TestObj", "cmp_obj"));
foreach ($a as $item) {
echo $item->name . "
";
}
?>
The above example will output:
b
c
d
Example #4
usort(3) example using a closure to sort a multi-dimensional array
<?php
$array[0] = array('key_a' => 'z', 'key_b' => 'c');
$array[1] = array('key_a' => 'x', 'key_b' => 'b');
$array[2] = array('key_a' => 'y', 'key_b' => 'a');
function build_sorter($key) {
return function ($a, $b) use ($key) {
return strnatcmp($a[$key], $b[$key]);
};
}
usort($array, build_sorter('key_b'));
foreach ($array as $item) {
echo $item['key_a'] . ', ' . $item['key_b'] . "
";
}
?>
The above example will output:
y, a
x, b
z, c
