What are the potential pitfalls when trying to rewrite Python code in PHP?

One potential pitfall when rewriting Python code in PHP is the syntax differences between the two languages. To address this issue, it is important to carefully translate Python code into PHP syntax, ensuring that all functions, loops, and data structures are correctly converted. Additionally, be mindful of any Python-specific libraries or features that may not have direct equivalents in PHP, and find alternative solutions when necessary.

// Example PHP code snippet demonstrating the translation of a Python function to PHP syntax

// Python code:
// def greet(name):
//     return "Hello, " + name

// Equivalent PHP code:
function greet($name) {
    return "Hello, " . $name;
}
