Syntax Error: Unexpected Token

Why This Happens

PHP's parser cannot understand the code structure. The unexpected token error means PHP encountered a character or keyword where it did not expect one. The actual mistake is usually on the line before the reported line, such as a missing semicolon, unclosed parenthesis, or missing operator.

The Problem

function calculate($a, $b) {
    $result = $a + $b
    return $result;
}

The Fix

function calculate($a, $b) {
    $result = $a + $b;
    return $result;
}

Step-by-Step Fix

1. 1

   Check the reported line and above

   The syntax error is often on the line before the one reported. Look for missing semicolons, unclosed brackets, or missing operators.

2. 2

   Match braces and parentheses

   Use your IDE's bracket matching feature to ensure all opening braces, brackets, and parentheses have matching closers.

3. 3

   Use a linter

   Run php -l filename.php to check syntax without executing the file. Your IDE should also highlight syntax errors in real time.
