PHP :: How Can I Convert Ascci Data To Blob (BINARY) String Type?

Convert Byte To Binary
I'm receiving 2 bytes of data from a socket connection.
They are shown as 2 unknown characters.

What I need to do is view their binary representation.

I've been playing around with unpack, but can't seem to get anywhere. Google hasn't helped a bit.

Like, if I just had "e" how could I convert that to "01100101"?

Convert Signed Hex Value To Big-endian Binary?
Anyone know how to convert this java code to php?

// Take the signature passed, a signed hexadecimal value and
// and convert to a byte array in 2's compliment, big-endian.
// We wrap in a try-catch in case the signature is not a signed
// hexadecimal number
byte[] barray = new BigInteger(signature,16).toByteArray();

Converting A Hex String To A Binary String?
I have a situation where I have an 8-byte string which is represented as 16 hex digits. How do I convert a 16 hex digit string to an 8-byte binary string?

I know I can use bin2hex to go from a binary string to a hex string (very useful)but is there a way to go the other direction? Right now I have a solution, which is to use a loop to go through the hex string one byte at a time, but that doesn't seem like a good way to do it. It seems like I should be able to use the pack() command, but I can't get it to work.

Blob Data - Timeout Issue
Hello,

I have success when uploading a binary file to a mysql "blob" type when a file is not larger than 2.5MB. When uploading a file >2.5MB, I get an error of MySql server has gone away or cannot allocate file and I get "Couldn't Add File to Database" .
I've read the manual on the error, but having checked all the settings i.e. max_allowed_packet=16M, php.ini settings of upload_max_filesize=16M, post_max_size=16M, max_execution_time=3600 and also httpd.conf timeout= 3600 and the error still persists. Is it mysql, php, apache or the script?

HTML:

<form enctype="multipart/form-data" name="frmUploadFile" action="grabfile.php" method="post">
<INPUT TYPE="hidden" NAME="MAX_FILE_SIZE" VALUE="16000000">

The script: grabfile.php

<?
$dbServer = "localhost";
$dbDatabase = "";
$dbUser = "";
$dbPass = "";

$fileHandle = fopen($fileUpload, "r");
$fileContent = fread($fileHandle, $fileUpload_size);
$fileContent = addslashes($fileContent);

$sConn = mysql_connect($dbServer, $dbUser, $dbPass)
or die("Couldn't connect to database server");

$dConn = mysql_select_db($dbDatabase, $sConn)
or die("Couldn't connect to database $dbDatabase");

$dbQuery = "INSERT INTO myBlobs VALUES ";
$dbQuery .= "(0, '$strDesc', '$fileContent', '$fileUpload_type')";

mysql_query($dbQuery) or die("Couldn't add file to database");

echo "<h4>Upload of $fileUpload_name is complete.</h4>";
echo "The details of the uploaded file are shown below:<br><br>";
echo "<b>File name:</b> $fileUpload_name <br>";
echo "<b>File type:</b> $fileUpload_type <br>";
echo "<b>File size:</b> $fileUpload_size <br>";

?>

Any suggestions?

BLOB Data As Src For Thumbnail Creation?
I have images stored on my MySql database as Binary "BLOB" filetypes. I want to make thumbnails of these files to display. I know how to create thumbnails using paths and image names of .jpg files. But I do not know how to use Binary"BLOB" image data to create them.

Do I have to encode the data in a certain format for the getimagesize(), ImageCreateFromjpeg() and imagejpeg() functions to work? Or does this have something to do with specifying a MIME type? I don't know how to get the functions to read the BLOBs.

How Do I Get Image Data Into A Blob Field

String Representation Of Hex To Binary?
I'm trying to verify some data which is posted to a php script from an external server. One of the posted fields is a signed hex number, but its obviously a string as part of the $_POST vars. I need to convert this value to a binary number so that it can be encrypted and then verified. Code:

Php, MySQL, And Binary Data
I'm trying to upload binary data and store it in mySQL as a mediumblob. Since there's always the possibility of quotes (along with any other character) within the binary stream, I assume I need to do something along the lines of AddSlashes to ensure that the sql request won't fail. The trouble is I'm finding that StripSlashes is blowing away the string when I retrieve it. I've tried rolling my own encoding, but ereg_replace("'", "'", $string) is truncating my data, apparantly at the first null character it hits.

So: what's a solution for safely getting binary data into mysql via php?

Sending Binary Data Via UDP
I'm trying to send a packet of binary data to a UDP server. If I send
a text string, it works fine. If I attempt to send binary data, it
sends a UDP packet with 0 bytes of data (just the headers). I can see
this because I'm running Ethereal and watching the packets.

I'm defining the packets as shown below:

$text_msg = "Hello, world
";
$binary_msg = chr(0x01).chr(0x02).chr(0x03).chr(0x00).chr(0xA0);
$binary_msg_size = 5;

Initially, I tried using
$fp = fsockopen("udp://" . $server,$port,$errno,$errstr)
and
fwrite($fp,$binary_msg,$binary_msg_size)

Since this didn't work, I then tried
$sock = socket_create(AF_INET,SOCK_DGRAM,SOL_UDP);
and
socket_sendto($sock,$binary_msg,$binary_msg_size,0 ,$server,$port);

For both methods, sending $text_msg worked, but sending $binary_msg
resulted in a UDP packet with 0 data bytes being sent.

I've found examples of sending binary data, but they used TCP, and
I've found examples of sending UDP, but they send text strings.

Anyone have experience with sending binary data to a UDP server?

Size Of Binary String On Multi-byte System?
if you are given binary data in a string (such as from a call to
fread), you can call the strlen function on this string to get its size:

$buffer = fread($file, 100000);
if (strlen($buffer) < 100000)
{
echo "read less than 100000 bytes";
}
etc

now, the problem is, on systems where you have the mbstring extension
turned on, and are using function substitution to replace strlen with
mb_strlen, you are pretty much guaranteed to get a WRONG value back from
strlen, since it will find some multi-byte lead characters in that binary
file eventually.

so the question is:

are there any other methods to find the length of a string besides strlen?
the only way i can see to not screw myself right now is to not use function
substitution.

Receiving Binary Data Using Sockets
I'm using sockets to communicate with an external device. This device sends out 5 bytes that I wish to receive and analyze. The problem I have is that the response I get seem to be converted into unicode(?)

Sending Binary Data With PHP Sockets
Is there any mean to send binary data with PHP using sockets? What I find so far is only sending and receiving Strings. I would be grateful if you could help me. Thanks.

Emailing Binary Data Question
I'm trying to create an 'email this picture' form using a php email class ("phpmailer"), & wish to embed the image in the body of the email, as opposed to attaching the image file.

The images are binary files referenced by fields in a mysql table, and are displayed using a function call that produces code without a .jpg extension - e.g. "<img src=img.php?f(3e7b67c7dd510)+w(45%)+h(45%)>" (I've used this script).

For the life of me I can't work out how to embed such an image into an email, & am thinking that maybe a workaround would be to rename the image with a simple .jpg title, save it to a temp directory, & delete after sending each email. What I'd like to know is:is this the best way to go forward?if so, how can it be done?

Send Binary Data To Socket
Quick & simple question:
I have to send the next data to a socket in order to make a popup visible on
a windows machine..

TITLE Title of popup [enter]
TEXT Text in popup [enter]
POPUP [enter]

<?
$s=socket_raw_connect($host,$port,15,'TITLE Test
TEXT Text in
popup
POPUP
');

function socket_raw_connect ($server, $port, $timeout,$request) {
if (!is_numeric($port) or !is_numeric($timeout)) {return false;}
$socket = fsockopen($server, $port, $errno, $errstr, $timeout);
if(!$socket) { echo "Opening socket error"; exit(); }

sleep(10); #Wait for program... bug :-)
$put=fputs($socket, $request);
sleep(10);
fclose($socket);
}
?>

Now, I have tried the whole scala of

x0a etc.. for
but it
doesn't seem to work..

Getting And Using Binary Image Data From ImageMagick
I am trying to use ImageMagick to create thumbnails on the fly - without
having to save the image to a file.

I have gotten it to work by using passthru($cmd, $retval), but I want to
use something else that will give me the complete output returned as a
string that I can convert to a GD lib image resource so I can verify the
operation worked before sending the Content-type header for the image.

This works:
---------------------------------------------------------
// $photo = path to image file
$cmd = "convert.exe -size 250x250 "$photo"" .
' -resize 125x125' .
' -strip' .
' -unsharp 0.2x0.6+1.0' .
' -quality 87 JPG:-'

header("Content-type: image/jpeg");
passthru($cmd, $retval);
---------------------------------------------------------

Using this, the resized image is displayed in my browser.

However, I would rather get the binary output from ImageMagick into a
variable and then test retval (or use some other method) to determine if
the operation was successful.

I've tried shell_exec ...
$output = shell_exec($cmd);
.... but the data in $output appears truncated (Ã¿Ã˜Ã¿Ã*ï¿½JFIFï¿½,,ï¿½ï¿½Ã¿Ã›ï¿½Cï¿½
- is all there is). ?

Updating Images (Binary Data)
I have a page that I use for users on my site to upload an image (displayed on their personal page).

Data Type Change Without Loosing Data

Reading Data From A Simple Binary File
I've read some discussions, searched Google, tried pack, unpack,
bin2hex, explode, implode, and I just can't figure out how to convert
this data. I am trying to read a file with the following format (two
examples).

41 6D 74 72 61 6B 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 75 05 1A 00

41 6D 74 72 61 6B 20 4F 6E 6C 69 6E 65 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 8F 05 2B 00

The first 28 bytes are a 00 terminated character string (in this case
"Amtrak" and "Amtrak online")
Next are the location (offset) of an entry in another file (2 bytes),
followed by that entry's size in the file (the next 2 bytes). The above
examples are key entries in an index file pointing to variable sized
entries in a data file.

I am using fread to put each field into a string variable (28 bytes, 2
bytes, and 2 bytes). The binary values are "Little Endian" (right?). In
other words 75 05 is really x0575 and 1A 00 is really x001A. I am having
the most trouble with these (I've already used bin2hex, but I don't know
how to convert the little endian to decimal.)

1. I want to strip the 00's from the string.

2. I want to convert the location (offset) into an integer variable.

3. I want to convert the size into an integer variable.

I am going to use location and size to fseek and fread the entries in
the data file into another string.

My actual goal is to transfer this data (the string and it's associated,
variable sized text field) into a MySQL database.

My guess is (was) that this is easy, but I just can't figure it out.

Update Mysql Blob With Another Blob Using Php
I have a blob field in a mysql database table. I want to copy a blob
from one record to another. I am having trouble transferring the data
via a php variable. Maybe I need to addslashes or convert to Hex or
something. I've tried a few things but can't quite get it. Here is
simplified code.

mysql_select_db($dbname, $connection);

$query = "SELECT blobthing
FROM mytable
WHERE id = 1;";

$results = mysql_query ($query, $connection);
$row = (mysql_fetch_assoc($result));
$varblobthing = $row['blobthing']; //put the blob in a variable

$query = "UPDATE mytable
SET blobthing = ".$varblobthing.",
WHERE id = 2;";

mysql_query ($query, $connection);

Convert STRING Charset
I have a MySQL database, which stores data in UTF-8 Unicode format. I have a webpage which has a form where I enter data to store the information and the CHARSET for that page is ISO-8859-1 (latin1).

When I fetch data from my database on a page that has the CHARSET ISO-8859-1 the output is great!
But when I now from another page has UTF-8 Unicode CHARSET set and fetch data from the database, some of the characters are messed up (like the Swedish Å Ä Ö characters).

My question follows:
Can I with PHP, fetch text from my database into a STRING and then "convert" from ISO-8859-1 to UTF-8 Unicode before outputting it to the page which has CHARSET UTF-8 Unicode? OR Do I have to "loop" through and replace "bad/wrong" characters into UTF-8 Unicode, and if so, HOW?

How Do You Convert A TCL List Into A String That PHP Can Read?
I have a TCL proc that needs to convert what might be a list into a
string to read

consider this:

[set string [PROPER_CASE {hello world}]]; # OUTPUTS Hello World which
is fine for PHP

[set string [PROPER_CASE {-hello world}]]; # OUTPUT {{-Hello}}
World, which PHP will print literally as {{-Hello}} World, instead of
-Hello World

Is there an easy way for TCL to brute-force a list into a
strictly-string-only format to prevent this potentially ugly display
from being displayed by PHP/etc.?

Convert String To Integer - Not Starting With A Number
I can't get PHP to convert a string to an integer (or pull the numbers OUT of a string) if it doesn't start with a number, which is an issue.

Basically, i'm trying to pull the integers only out of various model numbers for pieces of equipment our store is selling - examples would be something like S820D or MS1798. I only need the 820 or the 1798 from these strings, but PHP doesn't want to play nice with either:

$product_model = "S820D";
$var = intval($product_model);
or
$var = (int) $product_model;
