[SOLVED] Read specific line from a text file

[PC Nerd]

Hi all,

I'm looking to see if there is a better method than reading the entire file and then splitting it into an array ( at "\n").

I have a long text file, and I want to be able to select specific lines in the file.  Eventually I anticipate that the file could be into the tens or hundreds of thousands of lines long so I would like to try not to have to load the entire file everytime the script runs.

Thanks,PC_Nerd

file reads the file line by line into an array straight away.

Ok thanks,  but is there any specific way to read a specific line withought havbing to load the entire file ?

Thanks

Not really.

 

You can set a loop reading the file in line by line but this is long-winded and not the best option.

 

If each line is always the same length then you can calculate the start position but this will be doomed to fail if one line is different in length to the others.

Ok thanks,

 

Ive worked at the moment using file(); After reading in more depth about file(), I learned that the faster method it to manually read it from teh file using fread and then explode() based on a newline etc.

 

I think there is a solution in teh comments for file().

 

Thanks!
