Learn About PHP Array and Associative Array - Basic PHP

 

An array stores multiple values in one single variable: // Create an array

$numList = array(10,13,15,16,14,18,19,17);
$numList2 = [12,15,14,61,84,58,7];

print_r($numList);
echo "<br>";
echo "<br>";

// Create an associtaive array

$nameList = ['firstName' => 'Anil', 'lastName' => 'Singh'];
print_r($nameList);
echo "<br>";
// Sort array using inbuilt function

sort($numList);
print_r($numList);
echo "<br>";
// Reverse Sort array using rsort function

rsort($numList);
print_r($numList);
echo "<br>";

// Getting maximum value from an aaray
echo max($numList);

echo "<br>";
// Getting minimum value from array

echo min($numList);
$emp = [
