Symfony 2.8 Parse error: syntax error, unexpected ':', expecting ';' or '{' in c: \ xampp \ htdocs \ myproject \ path \ to \ AnnotationRegistry.php on line 50

Question

I downloaded and installed Symfony 2.8 from my own PC. I copied my project and entered it on the PC of our companies. I have not created and connected to the database yet. I tried to make php app/console server:run on c:\xampp\htdocs\ninjaz\ , but after that I got this error message.

Parse error: syntax error, unexpected ':', expecting ';' or '{' in C:\xampp\htdo cs\Ninjaz\vendor\doctrine\annotations\lib\Doctrine\Common\Annotations\Annotation Registry.php on line 50

Edit: My own PC has XAMPP since PHP 7.1. Our company PC has XAMPP PHP 5.5.19

This is the content of AnnotationRegistry.php:

 <?php namespace Doctrine\Common\Annotations; final class AnnotationRegistry { /** * A map of namespaces to use for autoloading purposes based on a PSR-0 convention. * * Contains the namespace as key and an array of directories as value. If the value is NULL * the include path is used for checking for the corresponding file. * * This autoloading mechanism does not utilize the PHP autoloading but implements autoloading on its own. * * @var string[][]|string[]|null[] */ static private $autoloadNamespaces = []; /** * A map of autoloader callables. * * @var callable[] */ static private $loaders = []; /** * An array of classes which cannot be found * * @var null[] indexed by class name */ static private $failedToAutoload = []; public static function reset() : void { self::$autoloadNamespaces = []; self::$loaders = []; self::$failedToAutoload = []; } /** * Registers file. * * @deprecated this method is deprecated and will be removed in doctrine/annotations 2.0 * autoloading should be deferred to the globally registered autoloader by then. For now, * use @example AnnotationRegistry::registerLoader('class_exists') */ public static function registerFile(string $file) : void { require_once $file; } /** * Adds a namespace with one or many directories to look for files or null for the include path. * * Loading of this namespaces will be done with a PSR-0 namespace loading algorithm. * * @param string $namespace * @param string|array|null $dirs * * @deprecated this method is deprecated and will be removed in doctrine/annotations 2.0 * autoloading should be deferred to the globally registered autoloader by then. For now, * use @example AnnotationRegistry::registerLoader('class_exists') */ public static function registerAutoloadNamespace(string $namespace, $dirs = null) : void { self::$autoloadNamespaces[$namespace] = $dirs; } /** * Registers multiple namespaces. * * Loading of this namespaces will be done with a PSR-0 namespace loading algorithm. * * @param string[][]|string[]|null[] $namespaces indexed by namespace name * * @deprecated this method is deprecated and will be removed in doctrine/annotations 2.0 * autoloading should be deferred to the globally registered autoloader by then. For now, * use @example AnnotationRegistry::registerLoader('class_exists') */ public static function registerAutoloadNamespaces(array $namespaces) : void { self::$autoloadNamespaces = \array_merge(self::$autoloadNamespaces, $namespaces); } /** * Registers an autoloading callable for annotations, much like spl_autoload_register(). * * NOTE: These class loaders HAVE to be silent when a class was not found! * IMPORTANT: Loaders have to return true if they loaded a class that could contain the searched annotation class. * * @deprecated this method is deprecated and will be removed in doctrine/annotations 2.0 * autoloading should be deferred to the globally registered autoloader by then. For now, * use @example AnnotationRegistry::registerLoader('class_exists') */ public static function registerLoader(callable $callable) : void { // Reset our static cache now that we have a new loader to work with self::$failedToAutoload = []; self::$loaders[] = $callable; } /** * Autoloads an annotation class silently. */ public static function loadAnnotationClass(string $class) : bool { if (\class_exists($class, false)) { return true; } if (\array_key_exists($class, self::$failedToAutoload)) { return false; } foreach (self::$autoloadNamespaces AS $namespace => $dirs) { if (\strpos($class, $namespace) === 0) { $file = \str_replace('\\', \DIRECTORY_SEPARATOR, $class) . '.php'; if ($dirs === null) { if ($path = stream_resolve_include_path($file)) { require $path; return true; } } else { foreach((array) $dirs AS $dir) { if (is_file($dir . \DIRECTORY_SEPARATOR . $file)) { require $dir . \DIRECTORY_SEPARATOR . $file; return true; } } } } } foreach (self::$loaders AS $loader) { if ($loader($class) === true) { return true; } } self::$failedToAutoload[$class] = null; return false; } } 

I managed to start the server by deleting those : void and : bool , but when I look at my project, it returns another error and the same with the first, but when I try to delete it again, it creates another error for other libraries. This is like an endless error after an error scenario. I do not know what to do now. I am new to symfony. Help is urgently needed.

This is caused by the wrong version of PHP. I had the same problem. You need PHP 7+. PHP in version lower than 7 does not support return type declaration.

You can also try adding the following code to your composer.json:

 { "config": { "platform": {"php": "5.6"} } }
