Re: [PHP] Re: Function variables in classes
OK guys, thanks for all your inputs.
Based on your guidance, I have tested the following code with a
series of variations:
class foobar {
function bar2 () {
echo Yep, in bar2() right now\n;
}
public function foo2 () {
$a = bar2;// Experiment 0
$a(); // Fatal error
}
}
And the variations:
$a = bar2;// Experiment 0
$a(); // Fatal error: Call to undefined function bar2()
$a = foobar::bar2;// Experiment 1
$a(); // Fatal error: Call to undefined function bar2()
$a = bar2;// Experiment 2
eval($a.();); // Fatal error: Call to undefined function bar2()
$a = foobar::bar2;// Experiment 3
eval($a.();); // Works but far from elegant
$a = bar2;// Experiment 4
$this-$a();// Works fine
$a = bar2;// Experiment 5
self::$a(); // Works fine
So, I have a working solution right now. But I still don't understand the
essence of the differences between experiment #1 and #4. Also, I don't
understand the need to specify the class name in experiment #3, coming
from #2. Functions bar2() and foo2() are part of the same class foobar,
and I would assume that the name 'bar2' would be in scope of the function
foo2.
BTW: I'm running PHP v5.2.0-8 build and distributed by Debian (etch1).
Thanks again and regards, Paul.

Is there any function where I would get

You could try something like:

$result[] .= $arrayDB2;

[PHP] Very Large text file parsing
I have a very large text file that gets dumped into a directoory every now and then. It is typically around 750MB long, at least, and my question is: What is the best method to parse this thing and insert the data into a postgres db? I have tried using file(), fget*() and some others, all with limited success. It goes through OK (I am sending it to a background process on the server and using a callback function to email me when done) but it is really knocking the machine hard, besides taking a real long time to finish. Is there a better way of approaching this?

Re: [PHP] Hide the real URL
At 7/26/2007 08:08 AM, M. Sokolewicz wrote:

why are you suppressing error messages??
@readfile($Filename);
http://php.net/readfile
Reads a file and writes it to the output buffer.
Returns the number of bytes read from the file. If an error occurs,
FALSE is returned and unless the function was called as @readfile(),
an error message is printed.
I figured that in the case of an image it would make more sense to
download a FALSE value to the browser than a text error
message. During development debugging phases error messages are
invaluable, but after publication some circumstances dictate no
display rather than display of a message. Since the OP was looking
for a solution that obfuscated the image URL, I thought the less
techy information communicated to the user the better.
Richard Heyes' suggestion of using passthru() might work better if it
can be used with a mixture of content types on the same page.
And, yes, heredoc is definitely a matter of taste. In my own work,
its disadvantage (hugging left margin) is outweighed by its
advantages (separation of logic from data/template/output, omission
of escape codes except the occasional {}, fewer typographical errors,
faster proofreading, etc.). I don't feel the need to convince anyone
else to use heredoc, but I'm totally sold on it myself.

Paul

Re: [PHP] Hide the real URL
At 7/26/2007 06:18 AM, elk dolk wrote:
I want to hide the real URL to my images by masking it with PHP
the code looks like this:
$query = SELECT * FROM table;
$result=mysql_query($query);
while ($row = mysql_fetch_array($result))
{
echo img src='http://www.mysite.com/img/{$FileName}'/;
}
if you look at the source in browser you will see:
img src='http://www.mysite.com/img/111.jpg' /
how can I show it like this:
img src='show.php?FileName=111.jpg' /
Your primary script would echo:
while ($row = mysql_fetch_array($result))
{
// get the file name from the data table
$FileName = $row['filename'];
// encode the filename to be legal in an URL
$FileName = urlencode($FileName);
// download to browser
echo _
img src=show.php?FileName=$FileName /
_;
}
and the secondary script show.php could use logic such as this:
// if the querystring contains the expected parameter
if (isset($_GET['Filename']))
{
// get requested filename
$Filename = 'img/' . $_GET['Filename'];
// if that file exists
if (file_exists($Filename))
{
// output to browser, suppressing
error message
@readfile($Filename);
}
}
Notes:
Your sample script included:
echo img src='http://www.mysite.com/img/{$FileName}'/;
Marking up your images as img ... / indicates that you want to use
XHTML. XHTML requires that attributes be quoted with double quotes,
not single quotes (apostrophes). Use http://validator.w3.org/ to
validate your markup.
However, simply reversing the quotes in your statement would result in:
echo 'img src=http://www.mysite.com/img/{$FileName}/';
This would not work because PHP would fail to expand the variable
name inside single quotes. Therefore you'd need to escape the inner
quotes like so:
echo img src=\http://www.mysite.com/img/{$FileName}\/;
or use heredoc (...) which I prefer to use because it means not
having to escape the quotes. In a case like this it also means not
having to enclose the variable in curly braces:
echo _
img src=show.php?FileName=$FileName /
_;
urlencode: http://php.net/urlencode
heredoc syntax: http://php.net/heredoc#language.types.string.syntax.heredoc
isset: http://php.net/isset
file_exists: http://php.net/file_exists

You can add the field data to a session:
$field1 = $_GET['field1'];
$_SESSION['field1'] = $field1;
// then to get them back again
if(isset($_SESSION['field1']))
{
$field1 = $_SESSION['field1'];

I need to figure out a way to populate/update the second drop down list based on a selection of the first one (the data for both drop down lists is in a MySQL database). Is this something I need to do in JavaScript? Or can I somehow trick PHP to do this? I don't think you need to trick PHP -- it will be friendly and cooperative as long as you feed it some nice juicy strings from time to time. The main difference between implementing this in javascript and implementing it in PHP is that PHP will require a round-trip to the server between menu changes, while javascript will act more immediately. Because javascript is so commonly disabled, I write the logic first in PHP so that everyone can use the page, then again in javascript to enhance the experience for folks with scripting enabled. This is not a doubling of work: both scripts can utilize the same datasets (since PHP is downloading the page it can feed javascript a version of the same data it uses), and both scripts have very similar syntax (they're really cousins) so it's possible in many cases to write nearly identical logic in key functions, reducing programming, debugging, and maintenance time. This technique is known variously as 'unobtrusive javascript' and 'progressive enhancement.'

I recall also running into \n\r although I can't recall which system uses it.
As an alternative to PCRE, we can pass arrays to PHP's replace functions, e.g.:

If that was wrapped in a function, sticking 'return false' within the
connect_error check is useful why exactly? Equally the fact the
function didn't 'exit' implies it 'returned true' anyway, so why check
it again in whatever called the function in the first place? it has
performed its task, it didn't raise an error.
(I know most of us would never use 'exit' in production code like the
above, so replace it with whatever error handling mechanism you have,
the question above remains the same.)
I demur at your final point: If we don't use exit() and the function
performs non-aborting error handling, it's going to return to the
calling function which in most cases will need to know whether its
child function succeeded or failed.
In most of the applications I write, an SQL error (not merely an
empty result set) indicates more often than not that the parent code
should gracefully withdraw from the process it was attempting to
perform. SQL errors are going to indicate a syntactical error in the
query, a missing table or field, a connection failure, or another
problem serious enough that the developer's attention should be drawn
to it. It's certainly possible in a thoughtfully-written application
for a parent function not to care whether a child SQL query was
successful on this fundamental level, but in most apps we'll want to know.
function parent()
{
lookUpData();
displayData();
}
function lookUpData()
{
set up query;
execute query;
handle errors;
}
where handle errors might range from returning a failure flag to
displaying an error message.
In order that displayData() doesn't fall on its face, I would write
the parent function in one of these ways:
if (lookUpData()) displayData();
in which lookUpData() returns true or false, the record set being
passed in a global variable (ugh);
or, if displayData() is smart enough to deal intelligently with a
null or empty result set:
$aResultSet = lookUpData();
displayData($aResultSet);
or:
displayData(lookUpData());
in which lookUpData() returns a dataset array that's empty if no
records were found or an error was encountered.
In my programming style, I can't imagine wanting to write this code
in such a way that lookUpData() didn't return some form of success or
error indicator.

If lookUpData falls flat on its face, my error handler will take over completely, finally resulting in an 'abortive' event, and never pass back to the parent. If an error is of a critical enough nature the system needs to stop. If it's not critical then the error handling within displayData() would detect it has nothing to display and error in its own accord. Hi Richard, If you write your applications like this then they'll fall over when something goes wrong -- and here I mean 'fall over' to mean aborting suddenly with a technical error message. That can be useful to us during development debugging but isn't really useful or friendly to the website visitor. It also gives every subroutine that handles errors the responsibility of deciding how to deal with the error -- whether to display it or not, how to display it, etc. It makes code less portable from one application to the next. Consider another model in which subroutines report errors back to the calling code but don't themselves 'act' on the errors. An error on a low level can bubble back up to some higher parent level in the application that knows what to do: whether to display and if so how and in what human language, whether to email the developer, whether to close down the application or continue, etc. An English SQL error message is of little use to a web page in Japanese. It's usually a mistake to display an SQL query in a public application because it exposes sensitive details of the database architecture. For example, we might want to generate the web page even if some part of its content is unavailable due to the SQL error. This leaves the visitor with a functional page from which they can navigate normally even if part of the content is missing. On this high level, the application might choose to behave nonchalantly as though SQL had returned an empty recordset and report the hard error to the webmaster behind the scenes. This kind of error-handling architecture can be handled in a variety of ways. One is to maintain a global error structure or class with a variety of fields that relate to the last error: true/false, error type, context, query code if applicable, etc. Because a low-level error may in turn trigger higher-level errors as it bubbles back up, it may make sense to turn this into an error stack to which each calling function adds its understanding of the problem as the error bubbles back up: 0: SQL error ZZZ in SELECT * FROM `users` ... 1: Can't query user list YYY 2: No users to display When a high-level function receives an error state from a called function, it can (if desired) walk down the stack to learn the technical origin of the error as well as its implications during the bubble-up. In my programming style, I can't imagine wanting to write this code in such a way that lookUpData() didn't return some form of success or error indicator. That's a *very* specific example though. My question was do people place a 'return' statement at the end of **ALL** of their functions, regardless of what that function actually did. In the code you gave there is a fair argument both ways, but that isn't always the case. Absolutely. I agree with most of the respondents to this thread: return a value only if the caller needs to receive a value back. Some languages (such as BASIC) distinguish between functions that return values and subroutines that don't. Because PHP gives only one type of function to call, with an option whether or not to return anything, it's clearly up to us to design and impose that architecture based on our knowledge and preferences.

At 5/30/2007 03:26 PM, Jared Farrish wrote:
You mean the delimiters (a la Richard's suggestion about using '|')?
Hi Jared,
If the pattern delimiter character appears in the pattern it must be
escaped so that the regexp processor will correctly interpret it as a
pattern character and not as the end of the pattern.
This would produce a regexp error:
/ldap://*/
but this is OK:
/ldap:\/\/*/
Therefore if you choose another delimiter altogether you don't have
to escape the slashes:
#ldap://*#
Cleaner and more clear.
preg_match('|^ldap(s)?://[a-zA-Z0-9-]+\.[a-zA-Z.]{2,5}$|', $this-server )
I also recommend using single quotes instead of double quotes here.
Single Quotes: Noted. Any reason why? I guess you might be a little out of
luck putting $vars into a regex without . concatenating.
Both PHP and regexp use the backslash as an escape. Inside double
quotes, PHP interprets \ as escape, while inside single quotes PHP
interprets \ as a simple backslash character.
When working with regexp in PHP you're dealing with two interpreters,
first PHP and then regexp. To support PHP's interpretation with
double quotes, you have to escape the escapes:
Single quotes: '/ldap:\/\/*/'
Double quotes: /ldap:\\/\\/*/
PHP interprets \\/ as \/
RegExp interprets \/ as /
There's also the additional minor argument that single-quoted strings
take less processing because PHP isn't scanning them for escaped
characters and variables to expand. On a practical level, though,
the difference is going to be measured in microseconds and is
unlikely to affect the perceptible speed of a typical PHP application.
So, for a pattern like this that contains slashes, it's best to use a
non-slash delimiter AND single quotes (unless, as you say, you need
to include PHP variables in the pattern):
$pattern = '#ldap://*#';
Personally I favor heredoc syntax for such situations because I don't
have to worry about the quotes:
$regexp = _
#ldap://*$var#
_;
why is there a period in the second pattern?
The period comes from the original article on SitePoint (linked earlier). Is
it unnecessary? I can't say I'm real sure what this means for the '.' in
regex's:
Matches any single character except line break characters \r and \n. Most
regex flavors have an option to make the dot match line break characters
too.
- http://www.regular-expressions.info/reference.html
Inside of a bracketed character class, the dot means a literal period
character and not a wildcard.
All non-alphanumeric characters other than \, -, ^ (at the start)
and the terminating ] are non-special in character classes
PHP PREG
Pattern Syntax
http://www.php.net/manual/en/reference.pcre.pattern.syntax.php
scroll down to 'Square brackets'
Also, why are you allowing for uppercase letters
when the RFC's don't allow them?
I hadn't gotten far enough to strtolower(), but that's a good point, I
hadn't actually considered it yet.
Perhaps it has to do with the source of the string: can you guarantee
that the URIs passed to this routine conform to spec?
Another way to handle this would be to simply accept case-insensitive strings:
|^ldap(s)?://[a-z0-9-]+\.[a-z.]{2,5}$|i
Pattern Modifiers

If this modifier is set, letters in the pattern match both upper

Sorry, I didn't mean to be disrespectful, I thought your question was more elementary than it was. There are, though, a ton of regular expression resources on the net. Google Is Your Friend. I just got a million hits on 'regular expression tutorial.' Maybe it's more practical to ask, When is it practical to use it? It matches anything, so I assume that means you can use it to match, say, a paragraph that you can't predict or match against? One that you're looking for a pattern match on one or either end? Well, sure. It often appears as .* meaning none or any number of any characters. Use it when you honestly don't care what it matches. Say you want to find out if the word frog occus in a text followed by the word dog. You could match on: /\bfrog\b(.*\b)?dog\b/i / pattern delimiter \b word boundary frog1st word \b word boundary ( begin subpattern .* zero or any characters \b word boundary ) end subpattern ? zero or one instance of the preceding subpattern dog 2nd word \b word boundary / pattern delimiter i case-insensitive This guarantees that both words are bounded by word boundaries and allows any number of any characters to occur between them. (There's sort of an implicit .* before and after the pattern. Because I haven't used ^ and $ to define the beginning and end of the text, regex looks for my pattern anywhere in the text.) And why is it called full stop? That's what the 'period' is called in British English. http://google.ca/search?q=define%3Afull+stop In English syntax period and full stop are synonymous, and the RegEx manual is throwing dot into the same bag.

You just shit on your professional reputation in public, in a very large room packed with your peers.

Nobody who's read this thread is going to believe you did anything but shit your pants on stage. I think you just have to relax and admit you screwed up.

Re: [PHP] Removing commas from number

Thanks to the suggestions, I use number_format($my_number, 2) to
format the number in an edit field. Now I need to reenter it into
MySQL. How should I use preg_replace to remove the commas?
This removes the commas *and* the decimal point:
preg_replace('/\D/', '', $str)
This strikes me as such an odd thing to do. If the MySQL table field
is defined as float, I don't see the need to remove the decimal point.
If you do need to store the digits without the punctuation, you could
also multiply by 100 and store it as an integer: intval($my_number *
100) which seems more efficient than to format as a string and then
reformat without the punctuation.
If I have two uses for a number -- say, formatted with commas and
other dressing for display and formatted more severely for SQL -- I'd
retain the number in a variable as its pure value and convert it for
each use, rather than converting it for one use and then converting
that for the next use. The software's more robust because a glitch
in a formatting operation isn't going to affect the final
result. Also, in many arithmetic circumstances where division is
involved, the true value of the results are accurate to more than two
decimal places. While these might be rounded to the nearest cent for
display purposes, you'll want to add the true values to get the true
total. One common example is a column of percentages that should add to 100%.

$number = $row-AMOUNT; // Get the double from MySQL
To display the number in the HTML edit field, I do

The user may enter a character that will not be accepted by MySQL, so I do
$mysql_number = preg_replace('/[^0-9^\.]/', '', $display_number);
Ah. I had earlier assumed that you were supplying the same numeric
value to two output destinations -- display and SQL. Instead, you're
taking a single value from SQL to input and another single value from
input to SQL. Even if you understand that these are the same number
in the context of the application, they could as easily be totally
separate because the two operations are disconnected from one another:
1) [SQL] -- [transform 1] -- [input]
2) submit form
3) [input] -- [transform 2] -- [SQL]
Transform 1 converts from the pure float value to a formatted string,
for which number_format() works fine. (You mentioned that these are
dollar amounts, but I wouldn't bother including the currency symbol
in with the input text, rather more like:
Enter price: $[__0.00]
where [___] is the input field.)
Transform 2 converts whatever the user has entered into a valid
numeric to pass to SQL. For many applications, I don't think a good
input validation routine would simply delete any non-numeric
character from the input. A user could erroneously type oh for zero,
el for one, or hit the shift key while typing a digit. Better, I
think, to preserve the input if it isn't valid and ask the user to
reconsider. Their own correction of their input might be
significantly different from a simple reduction.
A regular expression pattern to check for valid currency input might be:
[+-($]*\d{1,3}(,\d{3})*(\.\d*){0,1}\){0,1}
[+-($]* zero or more: plus, minus, open-paren, or currency symbol
\d{1,3} one to three: numeric digits
(,\d{3})* zero or more: comma-digit-digit-digit groups
(\.\d*){0,1}zero or one: decimal point followed by any number of digits
\){0,1} zero or one: close-paren
Any string failing to match this pattern could warrant an error message.
This example is of course dollar-oriented; you may wish to make your
logic apply equally to foreign currencies. Note that different
cultures have very different ways of expressing numbers -- comma for
the decimal point and period for the thousands separator, different
numbers of digits between separators, and different characters mixed
with the digits to indicate scale.
Once you accept the input, then you could delete all the characters
that aren't digits or period. Keep that decimal point, it's too
significant to lose.

Paul
