Check this link:

http://www.e-lephant.org/UserPictures/ShlomiKalfaPic.JPG

 

A. How come i can't see it in my FTP account file structure ?!

B. this is the page the created this file:

//Collect variables.
$UserID = "ShlomiKalfa";
$Picture = '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

What am i doing wrong ?!

[corbin]

$Picture = 'blah blah blah

 

should be $Picture = blah blah blah

 

 

Binary represented by hex is assigned like:

 

$b = 0x1;

[shlomikalfa]

oky.... even so... why isn't the file seen on my ftp client ?!

and why the hell doesn't it contain the data i want it to ?! i used the binary mode 'wb' which should allow me to create binary files.....

 

and yet it doesn't ......

[corbin]

Ahhh, just realized that hex data is stored numerically, so that will overflow the float limit.

 

 

Hrmmm, I'mma go try to write something.

[shlomikalfa]

oky, now that we've understood that thing... binary/hex is saved as a number and not as a string....

 

can we go further a head with my issue ?!

 

A, (can't see my files through ftp client) is solved, it is due to the fact my list files is updating only after a while....

 

how about why can't i see the picture ?!!?!

[Adam]

not too sure but try:

 

$Picture = "\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

 

Apparently "\x0C" is a special control sequence in PHP, like "\n" or "\r" that is specially for hexadecimal ASCII values..

 

??? worth a bash

[shlomikalfa]

well.. i tried to escape it as you suggested.... it doesn't work:

1. Tried to do it as you said... failed.

2. Tried to escape every byte solo:"\0xFF\0xD8\0xFF\0xE0\0x00\0x10\0x4A\0x46\0x49\0x46\0x00\0x01\0x01\0x01\0x00\0x60\0x00\0x60\0x00\...." Failed.

3. Tried to escape without "0x": "\FF\D8\FF\E0\00\10\4A\46\49\46\00\01\01\01\00\60\00\60\00\00\FF\E1\00\16\45\78\69\66\00\00\4...." Failed.

 

Well... As a string [inside ""] the file is opened and the content is written as is... it seems like it doesn't parse the ASCII binary data in the file, thus when opening the file with a text viewer afterward the "content" is written inside as is.... [WHILE NOT ESCAPING] and while escaping it, it just doesn't parse everything... as if it works only with some chars.....

 

Any Idea ?!?

Perhaps anyone can tell me how can i set the string into a binary data ?!

[kenrbnsn]

Please explain what you're trying to do with that string of HEX numbers.

 

Ken

[shlomikalfa]

that string of hex file is the content of a .jpg file in binary format.

 

i want to upload content to a php page through a program protocol which sends the file's binary data in a post method to the server...

 

so i am trying to stimulate it as if the data has already been received and save it.

 

Oky, meanwhile i've managed to solve it.

 

EDIT::

for others to come:

 

To change binary back into string use this function [non unicode support though]

function bin2asc($binaryInput, $byteLength=2)
{	
if (strlen($binaryInput) % $byteLength)
    {
        echo 'Impropper Format';
        return false;
    }
    // why run strlen() so many times in a loop? Use of constants = speed increase.
    $strSize = strlen($binaryInput);
    $origStr = '';
    // jump between bytes.
    for($x=0; $x<$strSize; $x += $byteLength)
    {
        // extract character's binary code
        $charBinary = substr($binaryInput, $x, $byteLength);
        $origStr.= chr(hexdec($charBinary)); // conversion to ASCII.
    }
    return substr($origStr, 1);
}
