How can error reporting be used to identify issues in PHP code that may cause the interpreter to fail?

Error reporting in PHP can be used to identify issues in code that may cause the interpreter to fail by displaying error messages that pinpoint the problem. By setting error reporting to a higher level, such as E_ALL, developers can catch warnings and notices that may indicate potential issues before they cause the script to crash. This proactive approach allows developers to fix errors before they become critical and ensures the smooth functioning of the PHP code.

// Set error reporting to display all types of errors
error_reporting(E_ALL);

// Example code that may cause an error
$variable = 5;
echo $variable; // This will generate a notice because $variable is not defined

// Fix the error by defining $variable before using it
$variable = 5;
echo $variable;
