I am not sure how to exactly explain what I am trying to do but I try to explain using an example.
$products = array("35","37","43");
Say if I have above array how can I create a result array that will look like this.
$related_products = array (
array (35,37),
array (35,43),
array (37,35),
array (37.43),
array (43,35),
array (43, 37)
)
You could use two loops to catch all combinations:
$products = array("35","37","43");
$result = array();
for($i = 0; $i < count($products); $i++) {
for($j = 0; $j < count($products); $j++) {
if($i !== $j) {
$result[] = array(
$products[$i],
$products[$j]
);
}
}
}
print_r($result);
Result:
Array
(
[0] => Array
(
[0] => 35
[1] => 37
)
[1] => Array
(
[0] => 35
[1] => 43
)
[2] => Array
(
[0] => 37
[1] => 35
)
[3] => Array
(
[0] => 37
[1] => 43
)
[4] => Array
(
[0] => 43
[1] => 35
)
[5] => Array
(
[0] => 43
[1] => 37
)
)
You can simply add one item to main array using array_push method like this,
$products = array("35","37","43");
$data = array();
for($i = 0; $i < count($products); $i++) {
for($j = 0; $j < count($products); $j++) {
if($i !== $j) {
array_push($data,array($products[$i],$products[$j]));
);
}
}
}
print_r($data);
