How can PHP developers troubleshoot and debug issues related to variable assignments and syntax errors in their code?

To troubleshoot and debug variable assignment and syntax errors in PHP code, developers can use tools like error reporting, debugging tools, and IDEs with syntax highlighting and error checking features. They can also use print_r() or var_dump() functions to check the values of variables and debug step by step using breakpoints.

<?php
// Example code snippet with variable assignment and syntax errors
$variable1 = "Hello";
$variable2 = 5;

// Debugging variable assignment issues
var_dump($variable1);
var_dump($variable2);

// Syntax error example
if ($variable2 > 3 {
    echo "Variable2 is greater than 3";
}
?>
