Hello,

I'm running PHP 4.0.6 and Apache 1.3.19 localhost on Windows 98,
with the latest Zend Optimizer 1.1.0 (PHP 4.0.6 compatible).

PHPBuilder has an article on: Storing Binary Data with PHP/MySQL
(http://phpbuilder.com/columns/florian19991014.php3)

The scripts:

1) Create a new database on your SQL Server:

CREATE TABLE binary_data (
id INT(4) NOT NULL AUTO_INCREMENT PRIMARY KEY,
description CHAR(50),
bin_data LONGBLOB,
filename CHAR(50),
filesize CHAR(50),
filetype CHAR(50)
); 

2) A sample php script you can use to store data in your database:

   store.php

<?php

// store.php - by Florian Dittmer <dittmer@gmx.net>
// Example php script to demonstrate the storing of binary files into
// an sql database. More information can be found at http://www.phpbuilder.com/
?>

<HTML>
<HEAD><TITLE>Store binary data into SQL Database</TITLE></HEAD>
<BODY>

<?php
// code that will be executed if the form has been submitted:

if ($submit) {

    // connect to the database
    // (you may have to adjust the hostname,username or password)

    MYSQL_CONNECT("localhost","root","password");
    mysql_select_db("binary_data");

    $data = addslashes(fread(fopen($form_data, "rb"), filesize($form_data)));

    $result=MYSQL_QUERY("INSERT INTO binary_data (description,bin_data,filename,filesize,filetype) ".
        "VALUES ('$form_description','$data','$form_data_name','$form_data_size','$form_data_type')");

    $id= mysql_insert_id();
    print "<p>This file has the following Database ID: <b>$id</b>";

    MYSQL_CLOSE();

} else {

    // else show the form to submit new data:
?>

    <form method="post" action="<?php echo $PHP_SELF; ?>" enctype="multipart/form-data">
    File Description:<br>
    <input type="text" name="form_description"  size="40">
    <INPUT TYPE="hidden" name="MAX_FILE_SIZE" value="1000000">
    <br>File to upload/store in database:<br>
    <input type="file" name="form_data"  size="40">
    <p><input type="submit" name="submit" value="submit">
    </form>

<?php

}

?>

</BODY>
</HTML>


3) A sample php script with which you can access the stored data  

   getdata.php

<?php

// getdata.php - by Florian Dittmer <dittmer@gmx.net>
// Example php script to demonstrate the direct passing of binary data
// to the user. More infos at http://www.phpbuilder.com
// Syntax: getdata.php?id=<id>

if($id) {

    // you may have to modify login information for your database server:
    @MYSQL_CONNECT("localhost","root","password");

    @mysql_select_db("binary_data");

    $query = "select bin_data,filetype from binary_data where id=$id";
    $result = @MYSQL_QUERY($query);

    $data = @MYSQL_RESULT($result,0,"bin_data");
    $type = @MYSQL_RESULT($result,0,"filetype");

    Header( "Content-type: $type");
    echo $data;

};
?> 

As the script needs to "know" which file is requested, you have to add the ID as a parameter. 
Example: A file has been stored with ID 2 in the database. To get this file, you have to call: 

   getdata.php?id=2 

-------------------------------------------------------------------------

OK, the scripts work GREAT, but here is where I have a problem:

1) I go into phpMyAdmin (Version 2.2.0)
2) Select my database
3) BROWSE the table - binary_data
4) Select EDIT on one of the items within the table...

Oddly enough, even though I get these 2 warning (or errors),
Apache does NOT crash... I can continue to browse other
databases in phpMyAdmin, and Apache continues to serve web pages?

Any idea what might be causing this?
