$n1 = $_POST['num1'];
$n2 = $_POST['num2'];
}

{
$n1 = 0;
$n2 = 0;
}
function UniqueRandomNumbersWithinRange($min, $max, $quantity) {
$numbers = range($min, $max);
shuffle($numbers);
return array_slice($numbers, 0, $quantity);
}
$numberArray = array(
UniqueRandomNumbersWithinRange(1,10,$n1),
UniqueRandomNumbersWithinRange(1,10,$n2))
?>
<form action="" method="post">
<input type="text" name="num1" placeholder="value 1"><br>

<input type="submit" name="submit">
</form>
<?php
printTable($numberArray); //panggilan function apa yg nk tunjuk
function printTable($numberArray) {
// Placeholder
$result = [];
// Setup the multiply
foreach ($numberArray[1] as $key1 => $value1) {
$tmp = array($value1); // add index y-axis
foreach ($numberArray[0] as $key0 => $value0) {
$tmp[] = $value0 * $value1;
}
$result[] = $tmp;
}
// Add index the x-axis
array_unshift($result, array_merge(array(" "), $numberArray[0]));
// display the result into table form
echo "<table border='1' align='center'>";
foreach ($result as $key => $value) {
echo "<tr>";
foreach ($value as $k => $v) {
if ($k == 0 || $key == 0) {
echo sprintf("<td><b>%s</b></td>", $v);
continue;
}
echo "<td>$v</td>";
}
echo "</tr>";
}
echo "</table>";
}
?>
Here can accept insert from user and auto generate number in array form which means user enter 5 in the textbox1 and 6 in the textbox2, it will generate number 3,4,5,2,1 and 2,3,4,1,2,3.
How I can capture this number put inside
$numberArray = array(
array($display1),
array($display2)
);
