Does it catch every syntax error like a real PHP parser?

No. This is a practical checker focused on matching parentheses and strings rather than a full PHP parser. For accurate syntax validation, check with a real PHP environment (php -l).

What happens if there's no '<?php' tag?

You'll see a warning, but it's fine to ignore if you're only checking a code fragment.

Is the code I enter sent to a server?

No. It's checked entirely in your browser.

🐘 PHP Syntax Checker

Checks whether the parentheses (){} [] in your PHP code are matched and whether strings are properly closed.

⚠️ Practical checker — not a full PHP-parser-based syntax check, focused on matching parentheses and strings

PHP Code

How to use

Enter your PHP code.
Click "Check".
The result shows whether parentheses, braces, and strings are matched.

🎯 Use Cases

Catch mismatched braces after writing a long function
Find unclosed string literals
Sanity-check code structure before pasting it in

Example

Input

<?php
function greet($name) {
    if ($name) {
        echo "Hello, $name";
    }

Output

• 2번째 줄: '{' 가 닫히지 않았습니다

The function's opening brace is never closed, so the checker flags that the '{' on line 2 is unclosed (the message text is Korean, meaning "line 2: '{' is not closed"). When everything matches, it shows "✅ All parentheses and strings are matched" instead.
