 hello,

 I have some problems with storing files in db and retriving them, so
 probably I'm doing something wrong :-)
 Here is the case:
 I have on one of the pages request to generate some PDF files and
 store them in database. So, I use FPDF to create files, and that's
 working perfect. Then my system is collecting generated file(s) and
 storing them in DB. On the other side (page)  I have to show stored
 files from database.

 So, when file (in this case PDF) is created and stored in some dir
 (ex. tmp/file.pdf), by using function: fopen(filename, 'r'); $file =
 fread(); I put file(s) in array $tmpArray = array('file' =>
 base64_encode($file) ) and send it to model (db). There I have
 table for files, (column type for file is BLOB). So, first I do the
 $fileThatWillBeStored = base64_decode($file); and than store it. After
 that I'm able to see that in DB there is one row with file, so that
 part is also ok.
 On the other side when I have to show that file, I just fetch it from
 DB and again pack it in array, but 

Re: [PHP] Signing (hand-written signature) pdf document

[Bastien Koert]

We use a signature pad and dll from m2sys for something similar to
this. It captures the signature, then creates a hash of the signature
to store in the db.

The only mobile app that I know that uses it is Square which is a
mobile payment system.

As for functions and class methods, there are lots of people who name

Maybe it's readable and great, but I have a little problem: I'm using
a screenreader, so the word "underscore" (and its Russian equivalent)
is too long for me. So I prefer

function TheGreatestFunctionInTheWorld () {

}

However, just discussed it with my wife. She prefers the same method
as me, though she doesn't use any screenreading software for
developing.

One of the best features of standards is that there are so many to
choose from. Likewise with coding styles, there are nearly as many as
there are coders. If you are working by yourself, pick something and
stick with it. If you are working in a group, or are employed to write
code, there may be requirements agreed upon or required in that
environment. You may not find out about them until your first code
review, but be assured, you will eventually be told about them.

Tedd-

Java has classes listed with an Uppercase. It could be JS you're thinking of 
but I'm not sure. Functions (except constructors) and variables have the 
lowerUpperCamelCase notation.

does anybody have negative thoughts on using the same naming format

i guess it's worth sharing! many thanks!

I like using $first_name.

I don't have any problems with using that convention for 
method/function/class names.


The only problem I have found (regardless of naming convention) is in 
using $_SESSION[]'s.


Sometimes:

$first_name = $_SESSION['first_name.'];

will cause problems. The solution is to use an index that's named 
different than the variable name, such as:


$first_name = $_SESSION['session_first_name.'];

Re: [PHP] storing files in database and retriving them

[Nilesh Govindarajan]

Dude! I found the bug probably, you're using fopen() in 'r' mode which
is meant to read ASCII text. Since PDF is a binary file (probably?),
you should use binary mode. Try with mode = 'rb' in fopen().

Re: [PHP] storing files in database and retriving them

[Dušan Novaković]

I don't think that it will help :-( I've tried to set different
headers but still I end up with some strange response, like:

%PDF-1.3
3 0 obj
<>
endobj
4 0 obj
<>
stream


So, if we try to look into this problem as basic. For example, I'm
trying to store file test.pdf from some location on server into my db
like this:

$fp = fopen(PATH_TO_PDF_FILE.'test.pdf', "r");
$size = filesize(PATH_TO_PDF_FILE.'test.pdf');
$type = mime_content_type(PATH_TO_PDF_FILE.'test.pdf');

$file = fread($fp, $size);

Here if I do : var_dump($file) how the content should look like?

$file = base64_encode($file);
close($fp);

$query = sprintf("INSERT INTO `table` SET `file`='%s', `name`='%s',
`size`='%s', `type`='%s'",
mysql_real_escape_string($file),
mysql_real_escape_string('test.pdf'),
mysql_real_escape_string($size),
mysql_real_escape_string($type)
);
mysql_query($query);



And lets try to retrive data now and show them on page:

$query  = sprintf("SELECT * FROM `table` WHERE `id`='something'");
$res= mysql_query($query);
$row = mysql_fetch_assoc($res);

 header("{$_SERVER['SERVER_PROTOCOL']} 200 OK", True, 200);
 header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
 header('Content-Length: ' . $row['size']);
 header('Content-Type: ' . $row['type']);
 header('Expires: 0');
 header('Pragma: public');

header('Content-Description: File Transfer');
header('Content-Disposition: attachment; filename=" . $row['name']);
header('Content-Transfer-Encoding: binary');

 readfile(base64_decode($row['file']));


And here I should get PDF file, but instead I get the same symbols on
the top of page :-(

Any suggestion? Some different header or ... ?

I've always found CKEditor (formerly known as FCKEditor after its
author) to be better than TinyMCE. It also has JQuery support should you
be using that Javascript framework. They also have plenty of example
documentation to integrate it with pretty much any server-side language
you need to, including PHP.

Thanks to all,

Thanks to all for suggestions, but of course i must to choose only one, 
and choose TiniMCE after suggestions of Dusan. Fala Dusan :)

Hello,

so when I'm sending the array to model it's like this:

$fp = fopen(INVOICE_PATH.date('Y-m-d').DS.$pdfName, "r");
$pdfContent = array(
'file'  =>
base64_encode(fread($fp,
filesize(INVOICE_PATH.date('Y-m-d').DS.$pdfName))),
'name'  =>$pdfName,
'size'  =>
filesize(INVOICE_PATH.date('Y-m-d').DS.$pdfName),
'type'  =>
mime_content_type(INVOICE_PATH.date('Y-m-d').DS.$pdfName)
);
fclose($fp);

so the data in db are ok, and this type is application/pdf.

And when I'm getting data, I get the array like this:

$file = Array
(
[id] =>  2
[file] =>VBERi0xLjM...<= here file is base64_encode()
[file_size] =>  2204
[file_type] =>  application/pdf
[file_name] =>  2_file.pdf
)

Headers:

header("Content-length: ".$file['file_size']);
header("Content-type: ".$file['file_type']);
header("Content-Disposition: attachment; filename= ".$file['file_name']);
echo base64_decode($file['file']);


So, mime looks ok, but still... not working :-(

Are you sure that you need Content-Disposition? Try removing that. I
think that's used only in emails (Correct me if I'm wrong).


You're wrong. Content-Disposition tells the browser how to handle the
content - in this case, the browser will download the file instead of
displaying it.

Regards
Peter



I think you need to be careful about quoting the file name in the 
Content-Disposition header: something like


header('Content-Disposition: attachment; filename="'.$filename.'.xml"');

seems to be the right quoting - the filename needs to be in double-quotes

As soon as you've got the data, create a hash of the file (sha1(),
md5(), etc.) and store that in the database.

When you restore the file, generate a new hash and compare it with the
stored one to make sure you've got the right data.

Assuming that the hashes match, then the next thing is to use a tool
like FireBug to see EXACTLY what is being received by the client. This
seems to be different to what you are sending.

The headers I use for a PDF file download (as compared to a PDF online
view) are ...

header("{$_SERVER['SERVER_PROTOCOL']} 200 OK", True, 200);
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Content-Length: ' . filesize($a_FPN['PDF']));
header('Content-Type: application/pdf');
header('Expires: 0');
header('Pragma: public');

// Force a Save Dialogue if that is required.
if ('True' === $b_Save)
{
header('Content-Description: File Transfer');
header('Content-Disposition: attachment; filename="Jobsheet ' .
$s_OrderNumber . '.pdf"');
header('Content-Transfer-Encoding: binary');
}

readfile($a_FPN['PDF']);

That normally doesn't stop people (mounting filesystems across the

Why are you storing files in the db in the first place? If they're
files why not use the filesystem?

That's all in the eye of the viewer: underscores are much prettier to
me in variables. That's all just a roundabout way of saying "it's
prettier" has no meaning on an objective level.

That confuses classes and functions - I prefer a naming convention
where classes and functions are named using different styles.
Personally I go for mixed-case for classes and camelcase for
functions, e.g. MyClass and myFunction(). Still, that's really just
personal taste and whatever makes you happy is the thing to go with.

Re: [PHP] storing files in database and retriving them

[Dušan Novaković]

Hello,

so when I'm sending the array to model it's like this:

$fp = fopen(INVOICE_PATH.date('Y-m-d').DS.$pdfName, "r");
$pdfContent = array(
'file'  =>  base64_encode(fread($fp,
filesize(INVOICE_PATH.date('Y-m-d').DS.$pdfName))),
'name'  =>  $pdfName,
'size'  =>  
filesize(INVOICE_PATH.date('Y-m-d').DS.$pdfName),
'type'  =>  
mime_content_type(INVOICE_PATH.date('Y-m-d').DS.$pdfName)
);
fclose($fp);

so the data in db are ok, and this type is application/pdf.

And when I'm getting data, I get the array like this:

$file = Array
(
[id] => 2
[file] =>VBERi0xLjM... <= here file is base64_encode()
[file_size] => 2204
[file_type] => application/pdf
[file_name] => 2_file.pdf
)

Headers:

header("Content-length: ".$file['file_size']);
header("Content-type: ".$file['file_type']);
header("Content-Disposition: attachment; filename= ".$file['file_name']);
echo base64_decode($file['file']);


So, mime looks ok, but still... not working :-(

Re: Re[2]: [PHP] Do you have some standard for defined the variable in program language?

[viraj]

yes andre, and in addition.. i have found the 'underscore' becomes a
handy delimiter character in certain cases. it's really helpful in
auto-loading and in calling user functions and in magic calls.

so, this is another reason to avoid 'underscore' in variable names.
code looks prettier and clean.

variables - $firstName
classes - MyBestClass
functions - TheGreatestFunctionInTheWorld
classes (auto-loadable) - Service_Maps (eg: maps class in service module)

hope this makes a neat coding style.

Re[2]: [PHP] Do you have some standard for defined the variable in program language?

[Andre Polykanine]

Hello viraj,

As for classes, it's suggested to start a class name with a capital:
class MyBestClass {
...
}

As for functions and class methods, there are lots of people who name
them like this:

function the_greatest_function_in_the_world () {
...
}

Maybe it's readable and great, but I have a little problem: I'm using
a screenreader, so the word "underscore" (and its Russian equivalent)
is too long for me. So I prefer

function TheGreatestFunctionInTheWorld () {
...
}

However, just discussed it with my wife. She prefers the same method
as me, though she doesn't use any screenreading software for
developing.

While on the topic of lack of coffee: I should know better than to
reply without checking the docs. strstr() returns a string, not a bool
- which would make it slower, though again, not noticeably so (unless,
like Ashley points out, you're doing a HUGE number of strstr() calls).

Peter

I like to use $firstName, and function firstName(), but I would use class 
FirstName.

Somehow in my mind, classes are important enough to earn the initial capital 
letter.

I tell a lie! Just checked the manual and strpos() is indeed the faster
than strstr(). I vaguely remembered it was one of the two, but had not
had quite enough coffee at this point of the morning obviously!

Having said that, I agree with Peter. There's unlikely to be a
noticeable difference unless working with thousands of iterations in a
loop using this function call.

[PHP] storing files in database and retriving them

[Dušan Novaković]

hello,

I have some problems with storing files in db and retriving them, so
probably I'm doing something wrong :-)
Here is the case:
I have on one of the pages request to generate some PDF files and
store them in database. So, I use FPDF to create files, and that's
working perfect. Then my system is collecting generated file(s) and
storing them in DB. On the other side (page)  I have to show stored
files from database.

So, when file (in this case PDF) is created and stored in some dir
(ex. tmp/file.pdf), by using function: fopen(filename, 'r'); $file =
fread(); I put file(s) in array $tmpArray = array('file' =>
base64_encode($file) ) and send it to model (db). There I have
table for files, (column type for file is BLOB). So, first I do the
$fileThatWillBeStored = base64_decode($file); and than store it. After
that I'm able to see that in DB there is one row with file, so that
part is also ok.
On the other side when I have to show that file, I just fetch it from
DB and again pack it in array, but first do the
base64_encode($fileFromDB) and send it to controller, where after
doing $file = base64_decode($fileFromDB); I just show it like this:
header("Content-length: ".$file['file_size']);
header("Content-type: ".$file['file_type']);
header("Content-Disposition: attachment; filename= ".$file['file_name']);
echo $file['file'];

And final result is something like:

%PDF-1.3
3 0 obj
<>
endobj
4 0 obj
<>
stream
x��W�v�F �� �L ��[�� N ��`'
�,{�� $�H�g� �/x�R?$� �Y� ��n=�U0t9"X ��h �O�)�  ��5���  � � �Q:��2B!U��( I)0

.


So, I hope you get the picture :-) Of course, I've skiped lot of
steps, because the code is huge.

Any suggestions? additional questions?

P.S.
I can't read on the other side file from directory, so it has to be in
the way I just described ( Generate PDF with FPDF => pack in array,
but first base64_encode => send it to model => get from array and
unpack it with base64_decode on DB side => store in DB, and then
reverse: get from DB => pack in array, but first base64_encode => send
it to controller => get it from array and unpack with base 64_decode
=> show in view with headers)

Thnx,
Dusan

I doubt there will be a noticeable difference between strstr and
strpos - returning a bool is not faster than returning an integer.
Would have to check the actual php source to see how the two are
implemented to see if there's any real difference that might make a
difference in speed.

There is no enforced standard on how you define your variable names in
PHP. However, you should try and remain consistent with whichever way
you decide to use. Personally, I find the $firstName style the best of
the four examples you gave. It's easily readable when I look over code
at a later date, and slightly faster to type than $first_name (although
even if only by a mere fraction of a second!)

Some existing codebases might use a particular method though, and if
you're working on a project with a team, then it really helps to all be
using the same convention of naming variables.

At the end of the day, this is all down to preference, along with code
indentation and layout.

If you only need to find if a string contains the character and not its
position, then strstr() (or strchr(), but according to the manual they
are both the same) is the fastest route to go down. Using strpos() is
slower because it has to return the actual position of what you were
looking for, and a regex will be the slowest of all (and one would have
to question the sanity of someone using a regex to find a single
character in a string!)
