fwrite Binary-safe file write &reftitle.description; intfwrite resourcehandle stringstring intlength fwrite writes the contents of string to the file stream pointed to by handle. &reftitle.parameters; handle &fs.file.pointer; string The string that is to be written. length 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. &reftitle.returnvalues; fwrite returns the number of bytes written, or &false; on error. &reftitle.examples; ]]> &reftitle.notes; Writing to a network stream may end before the whole string is written. Return value of fwrite may be checked: ]]> On systems which differentiate between binary and text files (i.e. Windows) the file must be opened with 'b' included in fopen mode parameter. If handle was fopened in append mode, fwrites are atomic (unless the size of string exceeds the filesystem's block size, on some platforms, and as long as the file is on a local filesystem). That is, there is no need to flock a resource before calling fwrite; all of the data will be written without interruption. If writing twice to the file pointer, then the data will be appended to the end of the file content: ]]> &reftitle.seealso; fread fopen fsockopen popen file_get_contents pack
