fwrite   is a smidgen faster and file put contents   is just a wrapper around those three methods anyway  so you would lose the overhead  Article     file put contents file data mode context     The file put contents writes a string to a file   This function follows these rules when accessing a file If FILE USE INCLUDE PATH is set  check the include path for a copy of filename Create the file if it does not exist then Open the file and Lock the file if LOCK EX is set and If FILE APPEND is set  move to the end of the file  Otherwise  clear the file content Write the data into the file and Close the file and release any locks  This function returns the number of the character written into the file on success  or FALSE on failure      fwrite file string length     The fwrite writes to an open file The function will stop at the end of the file or when it reaches the specified length  whichever comes first This function returns the number of bytes written or FALSE on failure
