reading file contents of a directory!? Any Words of Wisdom?

[jkrystof]

Currently I have a directory which will have a varying number of files. They are saved as

2.csv, 10.csv, 14.csv, 30.csv, etc.

I also have a file which I read into an array that has these file numbers, for example,

$filenumber[0]=2;
$filenumber[1]=10;
$filenumber[2]=14;

In this case I would like to do some additional work to 30.csv within the directory because the file number 30 is not within my array $filenumber.

Would anyone have any suggestions of how I can iterate through $filenumber and compare it's number to see if that number is a file within the directory? I want to ultimately do some more work on the file in the directory that is not within the array $filenumber.

I appreciate the help. Thanks 🙂

To start with, use [man]glob[/man] to get an array of file names.

After that, strip off the ".csv" from each of them, then use [man]array_diff[/man] to get a list of every number in $filenumber that is not in the array.
