fwrite Binary-safe file write intfwrite resourcehandle stringstring intlength fwrite writes the contents of string to the file stream pointed to by handle. If the length argument is given, writing will stop after length bytes have been written or the end of string is reached, whichever comes first. fwrite returns the number of bytes written, or &false; on error. Note that if the length argument is given, then the magic_quotes_runtime configuration option will be ignored and no slashes will be stripped from string. On systems which differentiate between binary and text files (i.e. Windows) the file must be opened with 'b' included in fopen mode parameter. ]]> See also fread, fopen, fsockopen, and popen.
