Not sure about laravel but i dont think you can have the fopen inside of the close like that, don't you need the handle to have its own var? like this: $fopen = fopen($file, 'w'); then use if (!fclose($fopen) || !$h = fopen($file, 'r')) maybe? – Fructification

thank you for replying when i uesd $fopen = fopen($file, 'w'); if (!$fopen || !$h = fopen($file, 'r')) it works but giving another error "404 NOT FOUND" – Reitareiter

Maybe your $file doesn't exist? And before you had it like this: if (!fclose($fopen) || !$h = fopen($file, 'r')) NOT like this if (!$fopen || !$h = fopen($file, 'r')). Not sure if that could have something todo with it. – Fructification

Have you tried restarting your machine? – Weathercock

i have treid restarting and gettting those error – Reitareiter

Please share more details - how is this related to composer-php or window? – Sodomy

i really dont know why this is affecting my whole project on this machine, when ever i run anything it gives that error, even though i run "composer update, it gives this error – Reitareiter

Answer 1

You can open the task manager then look for CLI (with the php logo) background process, if you find it then kill task

Answer 2

Don't restart, don't uninstall, don't panic !

If you are on Windows Machine then follow these below step :

1. Click the Start charm.

2. Type cmd, right-click the Command Prompt tile, and then click Run as administrator.

3. Type tasklist /v | find "php" press enter and find the PID of php.exe

4. Kill the process by taskkill /PID <PID> /F

5. You are done.

I had another Laravel application running that I forgot about (in the terminal of another IDE). Ctl + C (killing) that allowed me to get past this error msg.

Answer 5

First run composer install before trying to start the dev server using php artisan serve. You might also have to generate the key using php artisan key:generate incase the app starts with errors.

Answer 6

I encountered same issues I hope this solution help someone else:

1. Delete the **vendor** folder/directory of the project
2. run **"composer install"** to install packages.

That fixed my issues.

Answer 7

I've solved this issue by searching the process that was keeping open the file sf_proc_00.err within %LOCALAPPDATA%\Temp (the local Windows temp directory). Process Explorer or similar tools can be used for this. It was locked by ssh.exe (very likely launched by git). After killing the process, composer runs normally again.
