How can PHP error logs be utilized to identify and resolve issues in code execution?

PHP error logs can be utilized to identify and resolve issues in code execution by providing detailed information about errors, warnings, and notices that occur during script execution. By reviewing the error logs, developers can pinpoint the specific lines of code where issues are occurring and troubleshoot them accordingly. Additionally, error logs can help in identifying potential security vulnerabilities and performance bottlenecks in the code.

// Enable error logging in PHP
ini_set('display_errors', 0);
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Code snippet that may produce an error
$var = 'Hello';
echo $variable; // This line will produce an "Undefined variable" error

// Check the error log file for detailed information on the error
