How can one prevent parse errors in PHP code like the one mentioned in the forum thread?

To prevent parse errors in PHP code, ensure that all opening brackets '{' and closing brackets '}' are properly matched and balanced. Additionally, pay attention to syntax errors such as missing semicolons ';' at the end of statements. Using an IDE with syntax highlighting can also help catch these errors before running the code.

<?php

// Corrected PHP code snippet
$variable = 5;

if ($variable > 0) {
    echo "Variable is greater than 0.";
} else {
    echo "Variable is less than or equal to 0.";
}

?>
