There are various methods in PHP to get the first element of an array. Some of the techniques are the use of reset function, array_slice function, array_reverse, array_values, foreach loop, etc.

Example

Suppose we have an array like
$arrayVar = array('best', 'interview', 'question', 'com');

1. With direct accessing the 0th index:
echo $arrayVar[0];

2. With the help of reset()
echo reset($arrayVar);

3. With the help of foreach loop
foreach($arrayVar as $val) {
    echo $val;
    break; // exit from loop
}
