How can errors in code related to array position selection be identified and corrected in PHP?

Errors in code related to array position selection can be identified and corrected by ensuring that the array key exists before attempting to access it. This can be done using functions like isset() or array_key_exists(). Additionally, using proper error handling techniques such as try-catch blocks can help catch any potential issues with array position selection. 

// Example code snippet to identify and correct errors in array position selection
$array = ['a' => 1, 'b' => 2, 'c' => 3];

// Check if the key 'b' exists in the array before accessing it
if (array_key_exists('b', $array)) {
    echo $array['b'];
} else {
    echo "Key 'b' does not exist in the array.";
}
