Hi,

I have some hard coded variables that i want to re-write or update in the file.
How do i best update this?

lets says i want to set the hard written text:

$var_b=("the plant suddenly withers");
and
$var_d=("crying");

with these and replace them in the file?

$var_b=("the plant suddenly dies");
$var_d=("weeping");

how about using reg exp?

huh?

why?

ok how about.. instead of replacing the file line by line..

how do i erase the file and
re-write it?
is that easier?

how would i say:

$string_to_write = "$var_c=("romeo is dead");"

fputs($file,$string\n);

so i could actually write php syntax out to a file.

new to php so.. not sure how i escape these characters correctly.

thanks.
