What are common causes of parse errors in PHP scripts and how can they be resolved?

Common causes of parse errors in PHP scripts include missing semicolons at the end of lines, mismatched parentheses or curly braces, and syntax errors such as using a reserved keyword as a variable name. These errors can be resolved by carefully reviewing the code for any syntax mistakes and correcting them accordingly.

// Example of a parse error caused by a missing semicolon
$variable = "Hello, World" // Missing semicolon at the end of the line

// Corrected code with semicolon added
$variable = "Hello, World";
