问题 Hello fellow developers and problem-solvers. I've run into an issue with updating the header.php file in a WordPress website. Firstly, I tried updating the file manually through C-Panel -> File Manager. The code appears to stay in the file, but when you view the page source in incognito mode and different web browsers the code doesn't render. It's not a server problem, I already contacted the server support team and there aren't any error logs being reported by MySQL. There doesn't appear to

问题 foreach in PHP7 by default, when iterating by value, operates on a copy of the array according to: http://php.net/manual/en/migration70.incompatible.php Does it lazily create a copy only if there are changes made to the array or a value or will it always make a copy and in essence make looping over references a performance optimization? Also, do arrays of objects still loop over/give you references of the objects? Or will they actually also create copies for the foreach and return the objects

问题 I need to stream file content (such as images and other mime types) from a Lumen resource server to a Laravel client server. I know in Laravel I can use: $headers = ['Content-Type' => 'image/png']; $path = storage_path('/mnt/somestorage/example.png') return response()->file($path, $headers); However, the file method is absent in Laravel\Lumen\Http\ResponseFactory . Any suggestions are very welcome. 回答1: In Lumen you can use Symfony's BinaryFileResponse . use Symfony\Component\HttpFoundation

问题 I'm currently migrating a project from php5.6 to php7.1. Most is going well, but I just hit a wall one one test. The function usort doesn't have the same behavior on both version, and it doesn't seem to be documented (it's not that two values are equals and then the order is undefined). In my test case, the returned array order is reversed. Here is a reproduction of the problem. Note that I return -1 all the time for simplification (I'm focusing in the diff between PHP5.6 and 7 here) Code run

问题 On PHP5 it makes a whole lot of sense having both set_exception_handler() and set_error_handler() defined. However, on PHP7 all (most?) errors are now exceptions. So, what's the point on defining both handlers, if even errors would pass by the exception handler instead? I see there's a note on PHP7 new Error class in the exception handler doc, but there's no reference to the fact there's no plain errors anymore, but Throwable s, in the error handler function. Since PHP 7, most errors are

问题 I have uninstalled php7 and all its modules from ubuntu, and when I try to reinstall the modules, I get the following error for each php module, and although the module is installed, because of this error, it is not activated and I cannot use them. Is the any way to solve this issue ? the error for each module(when installing): Not replacing deleted config file /etc/php/7.0/mods-available/intl.ini WARNING: Module [module name] ini file doesn't exist under /etc/php/7.0/mods-available WARNING:

问题 I have an AWS server running on Amazon Linux. I used this guide to install php7 (bottom of the page): https://forums.aws.amazon.com/thread.jspa?messageID=695576 I would like to use nginx instead of Apache, so I've also installed the php70w-fpm and nginx packages. However, when I service start php-fpm , it does not create a php-fpm.sock file anywhere on my server. I have checked in /var/run and have also ran find / -name "*.sock" which only returns /var/run/rpcbind.sock . 回答1: Edit: The real

问题 Given code <?php function a(boolean $value){ var_dump($value); } a(true); I receive error TypeError: Argument 1 passed to a() must be an instance of boolean, boolean given What is going on here? 回答1: Only valid typehint for boolean is bool . As per documentation boolean isn't recognized as alias of bool in typehints. Instead it is treated as class name. Same goes for int (scalar) and integer (class name), which will result in error TypeError: Argument 1 passed to a() must be an instance of
