Q:

foreach - PHP - glob() returns no result when using $variable

Hey everyone,

I'm currently working on a PHP project and I'm facing an issue with the glob() function. So, the problem is that when I try to use a variable as the parameter in glob(), it returns no result. Let me explain it further.

I have a variable that contains a directory path, let's call it $directory. And when I try to use it like this: glob($directory), the function doesn't return any files or directories, even though there are definitely files present in that directory.

However, if I use the actual directory path directly in the glob() function like this: glob('/path/to/my/files'), it works perfectly fine and returns the expected results.

I've double-checked the value of $directory using var_dump() and it does contain the correct path. So, I'm really confused as to why glob() is not working when I pass the variable.

I have tried various solutions like using realpath() on the $directory variable before passing it to glob(), but it didn't make any difference.

Could someone please help me figure out what might be causing this issue? Am I missing something here? It would be greatly appreciated.

Thanks in advance.

Hey,

I had faced a similar issue with glob() function while using a variable as a parameter. It's worth mentioning that in my case, the variable $directory had an incorrect file path. It turned out that I was not correctly concatenating the path with the variable, resulting in an invalid directory path being passed to glob().

To resolve this, I made sure to double-check my concatenation logic and properly format the $directory variable. Also, if the directory path contains any variables or special characters, make sure to properly escape them.

I would recommend checking the logic of concatenating the variable $directory with the rest of the path and ensure that it forms a valid directory path. This simple mistake could be the reason why glob() is not returning any results.

Give it a shot and see if it resolves your issue. Good luck!

Hey there,

I've encountered a similar issue before with glob() function in PHP. In my case, the problem was with the variable containing the directory path. Turns out, the variable had some extra whitespace characters or special characters that were causing the glob() function to fail.

To fix this, I used the trim() function to remove any leading or trailing whitespace in the $directory variable before passing it to glob(). Something like this: glob(trim($directory)).

Additionally, I also made sure to check if the $directory variable was properly formatted and contained the correct path. Sometimes, simple mistakes like missing slashes or incorrect file extensions can cause glob() to not return any results.

I suggest you check the formatting of your $directory variable and make sure it does not have any unwanted characters. You can try using the trim() function and see if it resolves the issue.
