How can one troubleshoot and debug issues with arrays in PHP scripts?

To troubleshoot and debug issues with arrays in PHP scripts, you can start by checking for syntax errors, incorrect array keys or values, and ensuring that the correct array functions are being used. You can also use functions like var_dump() or print_r() to inspect the contents of the array and identify any potential issues. Additionally, using a debugger tool or adding error handling code can help pinpoint the source of the problem. 

// Example code snippet to debug and troubleshoot array issues in PHP

// Sample array with potential issues
$myArray = array(
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3',
);

// Check the contents of the array
var_dump($myArray);

// Accessing a specific element in the array
echo $myArray['key2'];

// Loop through the array
foreach ($myArray as $key => $value) {
    echo $key . ': ' . $value . '<br>';
}
