What are the potential issues with using single quotes versus double quotes in PHP strings?

Using single quotes in PHP strings can cause issues when trying to include variables or escape sequences within the string. Double quotes allow for variable interpolation and the use of escape sequences, making them more versatile. To solve this issue, use double quotes when you need to include variables or escape sequences in your strings.

$name = 'Alice';
echo "Hello, $name!"; // Output: Hello, Alice!
