How can PHP developers troubleshoot and resolve discrepancies between code snippets and error messages in their scripts?

When troubleshooting discrepancies between code snippets and error messages in PHP scripts, developers should carefully review the error messages to identify the specific issues. They can then compare the error messages with the corresponding code snippets to pinpoint the exact location of the problem. By debugging the code and making necessary corrections, developers can resolve the discrepancies and ensure the proper functionality of their scripts.

// Example code snippet with a common error
$num1 = 10;
$num2 = 0;
$result = $num1 / $num2; // Division by zero error

// Corrected code snippet
$num1 = 10;
$num2 = 5;
$result = $num1 / $num2; // Correct division operation
