What debugging techniques can be used to identify errors in PHP code?

One common debugging technique in PHP is to use the `var_dump()` function to display the contents of variables and arrays at various points in the code to identify any unexpected values or structures. Another technique is to enable error reporting by setting `error_reporting(E_ALL)` at the beginning of the script to catch any errors or warnings that may be occurring. Additionally, using tools like Xdebug can help trace the execution flow of the code and pinpoint the source of errors more efficiently. 

// Enable error reporting
error_reporting(E_ALL);

// Use var_dump() to display variable contents
$variable = "Hello, World!";
var_dump($variable);

// Implement Xdebug for more detailed debugging
// (Xdebug configuration settings can be found in php.ini file)
