A PHP error like:

nginx
КопироватьРедактировать
Parse error: syntax error, unexpected token "use"

means that PHP encountered the use keyword in a place where it wasn’t expecting it.

This usually happens for one of these common reasons:

✅ 1. Misplaced use Statement

You can only use the use statement:

• At the top of a PHP file (outside of classes/functions)

• Or inside a closure, for importing variables

❌ Wrong:

php
КопироватьРедактировать
function myFunction() {
    use My\Namespace\ClassName; // ❌ Parse error
}

✅ Right:

php
КопироватьРедактировать
use My\Namespace\ClassName;

function myFunction() {
    $obj = new ClassName();
}

Or, in closures:

php
КопироватьРедактировать
$var = 5;
$fn = function () use ($var) {
    echo $var;
};

✅ 2. PHP Version Compatibility

If you're using PHP < 5.3, use for namespaces doesn't exist yet.

If you're using use in closures, you need PHP ≥ 5.3.

Check your PHP version with:

bash
КопироватьРедактировать
php -v

✅ 3. Trait use Inside Class

Make sure use for traits is inside a class, like this:

php
КопироватьРедактировать
class MyClass {
    use MyTrait;
}

✅ 4. Syntax Errors Above the use Line

Often the real issue is a missing semicolon or bracket above the use line. For example:

php
КопироватьРедактировать
<?php
echo "Hello" // ← missing semicolon

use My\Namespace\ClassName; // ← this line causes error, but the problem is above

🔍 How to Fix It

1. Check if you're using use in the wrong place (inside function/class?).

2. Ensure your PHP version supports use (≥ 5.3).

3. Check for syntax errors above the error line.

4. Post the few lines around the error if you want help pinpointing it.

If you share the code around the error, I can tell you exactly what's wrong.
