The file_put_contents() function is only supported on PHP v >= 5; the
indication mixed data means that it can be anything from a scalar to an
array.

An alternative for file_put_contents on PHP 4.x would be to apply fopen
with ``wb'' as the switch and fputs for writing:
$fp = fopen("somenewfile", "wb");
fputs($fp, $data_1 . $data_2);
fclose($fp);
Since file_get_contents() is binary safe, the binary data will be
untouched and the merge successful, provided that the binary data
actually can be merged this way...
