How can IDEs help in identifying and preventing issues with uninitialized variables in PHP code?

Uninitialized variables in PHP code can lead to unexpected behavior and errors in the program. IDEs can help in identifying these issues by highlighting uninitialized variables and providing warnings or suggestions to initialize them before use. By following the IDE's suggestions, developers can prevent runtime errors and ensure the code runs smoothly. 

// Example of initializing a variable before use to prevent issues with uninitialized variables
$name = ''; // Initialize the variable

// Now the variable can be safely used without causing any issues
echo "Hello, $name";
