What are common pitfalls when dealing with quotation marks in PHP code?

One common pitfall when dealing with quotation marks in PHP code is forgetting to properly escape them when using them within a string. This can lead to syntax errors or unexpected behavior in your code. To solve this issue, you can use the backslash (\) character to escape the quotation marks within the string.

// Incorrect way without escaping quotation marks
$string = "This is a "wrong" way to use quotation marks in PHP";

// Correct way with escaped quotation marks
$string = "This is the \"correct\" way to use quotation marks in PHP";
