Detect line from text file

[mekdonel]

Hi,

 

I have a text file that list out several activation code

aaaaa1
aaaaa2
aaaaa3
aaaaa4
aaaaa5

 

Then I will create a form which user will enter the line number of the text file to get the activation code. Eg user enter '2', so the system will pop out 'aaaaa2'.

 

The Problem is I really stuck on how to get php call the line number in the text file.

 

Any help will be grateful. Thanks

Open the file using the file function like so:

$line = file('path/to/file');

 

file opens up the file and puts each line in to an array, eg: $line[0] is line 1, $line[1] is line 2, $line[2] is line 3. Remember array indices start at 0 and not 1.
