How can I get the first element of an array in PHP?

How can I get the first element of an array in PHP? The solution is easier than you might think, by using PHP's reset and current, array_pop, or array_shift functions.

Get the first element of an array in PHP

PHP uses array pointers to keep track of which element is currently being used, during the runtime of PHP. If we want to get the first element of an array we can use reset and current, two of which are PHP functions. Using reset tells PHP that we want the pointer to go to the start and current then outputs where the current array index pointer is. Because we've reset the pointer it's going to output the first element of the array.

$array = ['red', 'blue', 'yellow', 'orange'];
echo current($array);

# Outputs 

Using array_reverse and array_pop to get the first element of an array

If you require to keep the array pointer in the current position, we can clone the array to another variable and use array_reverse. Here we are reversing the array and then popping off the last element in the array to give us what was the first element of the array. Doing it this way preserves the original array index, helpful if it is being used later.

$array = ['red', 'blue', 'yellow', 'orange'];
$reversedArray = array_reverse($array);
echo array_pop($reversedArray);

# Outputs 

Using array_shift to get the first element in an array

Alternatively, we can use array_shift which allows us to obtain the top element in a PHP array. By giving the same array to the function, it will return to the top element.

$array = ['red', 'blue', 'yellow', 'orange'];
echo array_shift($array);

# Outputs 

It's important to note that using array_shift to obtain the first element does in the process remove it from the array.


# Outputs
 [0] => blue
 [1] => yellow
 [2] => orange
