How can error reporting functions in PHP, such as error_reporting(E_ALL) and die(mysql_error()), help in troubleshooting SQL syntax errors?

Error reporting functions in PHP, such as error_reporting(E_ALL) and die(mysql_error()), can help in troubleshooting SQL syntax errors by providing detailed error messages that indicate the exact issue in the SQL query. By setting error_reporting(E_ALL), it ensures that all errors, warnings, and notices are displayed, making it easier to identify syntax errors. Additionally, using die(mysql_error()) immediately stops the script execution and displays the MySQL error message, allowing for quick identification and resolution of SQL syntax errors. 

<?php
// Enable error reporting to display all errors
error_reporting(E_ALL);

// Example SQL query with syntax error
$query = "SELECT * FROM users WHERE username = 'john'"

// Execute the query and check for errors
$result = mysql_query($query) or die(mysql_error());

// Further code execution
?>
