Writing to an exact Ln, Col of a file

[Freedom-n-Democrazy]

Is it possible to write to an exact line and column of a text file with PHP like with fwrite or something?

Possible? yes.

You'll probably have to read the entire text file into a variable, split it into lines, find the line you want, split it into columns, write your changes, then save the whole thing back into the text file. As long as you know how the text file is structured, it should be quite easy. (although not very practical, and error prone)

You could use file(), then select the line from the resulting array.  You would then have to know the file specifics in order to be able to explode() the line down to get the right column.

 

After all of this, you would need to put it all back together, and file_put_contents().
