What does the "Operation now in progress" error message mean?

Question

When trying to open a file with this command:

$fd = fopen('majestic_files/majestic_record.txt','w'); 

The following error message appears:

 <b>Warning</b>: fopen(majestic_files/majestic_record.txt) [<a href='function.fopen'>function.fopen</a>]: failed to open stream: Operation now in progress in 

What does this mean and how to fix it?

Answer 1

This occurs when an outstanding lock operation is performed.

In this context, an error implies that another process has a lock in the file, most likely due to an open and written file, because the process locks the lock.

Answer 2

It is not directly related to the issue of OP, but if you get this error using the Laravel structure, there is a chance that the autoloader will not be able to find one of the classes. For example, this can happen if you move the class to another directory without resetting the autoloader.

To fix this, try composer dumpautoload .

Answer 3

I encountered this error "could not open the stream: operation in progress" after accidentally traversing only the path, not the full path and file name, to parse_ini_file .

Answer 4

I received this error message while trying to connect to an invalid local IP address. Fixing the host I was connecting to resolved the issue.

Answer 5

I think you need to add "/" at the beginning of the line of the file ... just an idea without a guarantee
