How to Get the First Element of an Array in PHP

  184 views   3 months ago PHP

Use the PHP array_values() Function

If you know the exact index or key of an array you can easily get the first element, like this:

<?php
// A sample indexed array
$cities = array("London", "Paris", "New York");
echo $cities[0]; // Outputs: London
 
// A sample associative array
$fruits = array("a" => "Apple", "b" => "Ball", "c" => "Cat");
echo $fruits["a"]; // Outputs: Apple
?>

However, there are certain situations where you don't know the exact index or key of the first element. In that case you can use the array_values() function which returns all the values from the array and indexes the array numerically, as shown in the following example:

<?php
$arr = array(3 => "Apple", 5 => "Ball", 11 => "Cat");
echo array_values($arr)[0]; // Outputs: Apple
?>
