How to Add Elements to an Empty Array in PHP

Topic: PHP / MySQLPrev|Next

Answer: Use the array_push() Function

You can simply use the array_push() function to add new elements or values to an empty PHP array.

Let's take a look at an example to understand how it basically works:

<?php
// Adding values one by one
$array1 = array();
array_push($array1, 1);
array_push($array1, 2);
array_push($array1, 3);

print_r($array1);
echo "<br>";

// Adding all values at once
$array2 = array();
array_push($array2, 1, 2, 3);

print_r($array2);
echo "<br>";

// Adding values through loop
$array3 = array();
for($i=1; $i<=3; $i++){
    $array3[] = $i;  
}

print_r($array3);
?>
