You are a livesaver! Thanks very much. I got one more problem though:
What's the best way to create a string with a fixed length, that's 
padded with zero-bytes?

I'm currently using:

php_stream_write(stream, Z_STRVAL_P(*data), 30);

As the string is terminated with a zero-byte, it already works, but it 
would be better to fill the unused space with zero-bytes.

Do I have to create a second buffer and copy byte-by-byte and then fill 
the remaining bytes with zeros, or is there an easier way? The only 
other solution I could think of is to check for the exact length of the 
string, write the string and then use php_stream_putc() in a loop to 
write the remaining zero bytes...
