But I think he'll still have an issue when he goes to transmit it. Whatever data you have is going to be interpreted by the function doing the sending unless it's a "binary safe" function that's going to send raw binary.
Thanks for the tip on "pack" though. Havn't needed it yet, but always good to know. And PHP has so many functions (I'm constantly amazed that it usually has a function for whatever I need). -TG > -----Original Message----- > From: DvDmanDT [mailto:[EMAIL PROTECTED] > Sent: Thursday, January 29, 2004 6:58 PM > To: [EMAIL PROTECTED] > Subject: Re: [PHP] sending a hex string as it is? > > > No need to ge that deep (socket_create and stuff).. > To send the HEX number 20 (also a space), you can do the following: > > "\x20"; > chr(0x20); > chr(hexdec('20')); > pack('C',0x20); > > All of those _should_ create a space... > -- > // DvDmanDT > MSN: dvdmandt€hotmail.com > Mail: dvdmandt€telia.com > "Trevor Gryffyn" <[EMAIL PROTECTED]> skrev i meddelandet > news:[EMAIL PROTECTED] > RCARGO.COM... > Ahh..
