Question re: fwrite

duckduckgoose

Two questions really:

(1) Is it possible to add text to the beginning of a file? I tried using r+, but that just overwrites what was already there. I tried using w+, but that that also overwrites what was already there. I tried using a+, and that adds text to the end of the file.

(2) Is it possible to add text at a specific location in a file?

Thanks much!

do what i do. google it.

php file manipulation tutorial.

i forget it off hand but it's the the read/write access you have to the file that matters too much it's the actual function. i've done this for an installer where i create a config file for some other files need to use.

i think you have to read the file, and specify how many charachters inward in that wile you want to write....i found it a little confusing :queasy:

You could read the file contents into a string with [man]file_get_contents/man, prepend your text to the string, and then write back.
You could fopen() in r+ mode, [man]fseek/man to the point that you want, and then read (into a string) from that point to the end of the file. After that, prepend your text to the string, fseek() to the location, and write back.

There might be better ways, I personally had little cause to work with such file manipulation.
