How can a novice PHP programmer effectively troubleshoot issues with generating and storing random numbers in an array?

Issue: A novice PHP programmer may encounter issues when trying to generate and store random numbers in an array due to incorrect syntax or logic errors in their code. To effectively troubleshoot this issue, the programmer should carefully review their code for any mistakes, ensure that the random number generation function is being called correctly, and verify that the random numbers are being stored in the array as intended.

// Generate and store random numbers in an array
$random_numbers = array();

for ($i = 0; $i < 10; $i++) {
    $random_numbers[] = rand(1, 100); // Generate a random number between 1 and 100 and store it in the array
}

// Display the generated random numbers
print_r($random_numbers);
