It s creating the file in the same directory as your script   Try this instead    content    some text here    fp   fopen   SERVER  DOCUMENT ROOT       myText txt   wb    fwrite  fp  content   fclose  fp

fopen   will open a resource in the same directory as the file executing the command   In other words  if you re just running the file   test php  your script will create   myText txt   This can get a little confusing if you re using any URL rewriting  such as in an MVC framework  as it will likely create the new file in whatever the directory contains the root index php file   Also  you must have correct permissions set and may want to test before writing to the file   The following would help you debug    fp   fopen  myText txt   wb    if   fp    false          do debugging or logging here  else      fwrite  fp  content       fclose  fp

If you are running PHP on Apache then you can use the enviroment variable called DOCUMENT ROOT  This means that the path is dynamic  and can be moved between servers without messing about with the code    lt  php    fileLocation   getenv  DOCUMENT ROOT       myfile txt      file   fopen  fileLocation  w       content    Your text here     fwrite  file  content     fclose  file     gt
