Re: [PHP] echo SESSION var doesn't work if unset after echo
I have two vars doing the same thing. One is echo'd/unset in the
head/head section and the other echo'd/unset in the footer of the page.
No re-direct request is being made.
Ok now check this. If I use this code:
if(isset($_SESSION[Ecomm])) {
echo $_SESSION[Ecomm];
unset($_SESSION[Ecomm]);
}
I can *NOT* see the Ecomm contents in the right-click - View Page Source.
I do see the complete in the View Generated Source.
Now, If I comment out the unset:
if(isset($_SESSION[Ecomm])) {
echo $_SESSION[Ecomm];
// unset($_SESSION[Ecomm]);
}
Then I *CAN* see the Ecomm code in the in the right-click - View Page
Source as well as the View Generated Source.
I am very humbled right now.

I don't think anyone mentioned a redirect request. Rather, to speed up
loading of pages, browsers make simultaneous GET requests for the page.
This is why forms should always use GET to retrieve data that will not
change, and POST to change data or state.

That's pretty cool. I wasn't sure if it would work with numerically
indexed arrays, so I tried:
// sillyFunc returns array(0=1, 1=2);
ArrayClass::create(sillyFunc())-{0}
I just tested it, and that works. If you leave off the curly braces and
quotes, then you obviously get a parse error. The curly braces are
necessary.

the idea is that you get something that can be used repeatedly. in your
example you are creating the array that is supplied to the
ArrayClass::create() method, whereas in mine it is supplied by something
else. of course you could create a global function that wraps the
ArrayClass::create() method, and in that case it might make sense to leave
the constructor public and just wrap the instantiation of the ArrayClass
class. but thats why i created the static method in the first place, that
and the issue we observed a while back about not being able to invoke a
method on an object in the same statement that instantiates it.

I'm sure you meant consider. Concider sounds like fake cider ;)

Doesn't work that way, he needs the reference in that last one. The last
one is a pseudo solution since it requires the helper reference which
gets littered in the calling scope.

That's not cool, that's a mess. Why doe sit happen the way it does?
First off, print() is a function so nesting functions means the
innermost functions get processed first, this is why the output has
mangled order. The 1's show up in the output because you're
concatenating the return value of the print() function which is true for
success.

RE: [PHP] echo VS print : that's a cool behavior !
Hello everyone.
We all know the difference between print and echo, but has someone ever
tried to combine them together ??
Right, try this :
?php
echo coucou . print('v ' . print('u ' . print('toctoc ') . 'hihi ') ) .
'tata ' . print('zozo ' . print('pupu '));
And guess the result ...
Can someone explain it ?
( the result is : toctoc hihi u 1pupu zozo 1v 1tata 1coucou 1 )

My bad, print is not a function, and so:
print( 'toctoc ' ).'hihi ';
is equivalent to:
print( 'tocktoc '.'hihi ' );
Parenthesis are option and only server to control precedence. But unlike
echo print does return a value.

Ah. I see. I knew they were optional, but I didn't know that when you
include them PHP evaluates ('toctoc') before it passes the value off
to print(). I just figured that with or without the parentheses it
would pass 'toctoc' to print() and return a result that would be
concatenated inline with the other values. I guess that's the part I
didn't understand about the difference between a function and a
language construct in PHP.
As for the OP, I still don't know why anyone would even dream of
creating code that does this other than to see what would happen if
we :-)

Re: [PHP] echo date('Y-m-d', $mydata-timestamp);
Use the MySQL function that converts timestamp into Unixtime.
Or, better yet, use the MySQL function that outputs exactly the date
format you want, without dinking around with Unix timestamp in the
middle.
http://dev.mysql.com/
Search for date_format() I do believe.
It's gonna be a whole lot like PHP 'date' function, only with % signs,
as I recall.

date() takes a Unix timestamp as its input.
Unix timestamps are measured as number of seconds from Jan 1, 1970,
midnight, GMT, the birth of Disco.

You are handing it a pre-formatted date-stamp in MMDDHHIISS
format...
You could do something like:
$t = '20070419162123';
$year = substr($t, 0, 4);
$month = substr($t, 4, 2);
$day = substr($t, 6, 2);
$hour = substr($t, 8, 2);
$minutes = substr($t, 10, 2);
$seconds = substr($t, 12, 2);
echo date(mktime($month, $day, $year, $hour, $minutes, $seconds));
I suspect strtotime() *might* handle your input and give you a Unix
timestamp...
I also suspect whatever you needed a Unix timestamp for in the first
place could have been achieved easier before you got painted into
this
corner...

Well, then just use the query to decide how it should look like.
Mysql timestamp is amazingly easy to work with.
whatevertable,date_format(timestamp_table, 'what should it look like') as
timestamp or use another name if you need both like I do.
Now what? I was hoping to avoid:
|echo substr(|$mydata-timestamp|, 0, 8);

date() takes a Unix timestamp as its input.
Unix timestamps are measured as number of seconds from Jan 1, 1970,
midnight, GMT, the birth of Disco.

You are handing it a pre-formatted date-stamp in MMDDHHIISS format...
You could do something like:

the simplest answer is actually yto make mySQL give you
the data in unix timestamp format in the first place:
SELECT UNIX_TIMESTAMP(my_field) AS my_timestamp FROM foo WHERE id=1;

RE: [PHP] echo date('Y-m-d', $mydata-timestamp);
You are misunderstanding what timestamp means. The value of a timestamp
is from UNIX epoch http://en.wikipedia.org/wiki/Unix_time. It is
calculated by the number of seconds after January 1st, 1970. Also note,
that you are overflowing the integer, which is giving you a
http://en.wikipedia.org/wiki/Year_2038_problem Y2K38 problem.
If you want the UNIX timestamp of 4/19/2007 16:21:23, you can do
mktime(16,21,23,4,19,2007);
(http://us.php.net/manual/en/function.mktime.php).

There is a difference, echo is slightly faster.

it displays 10 times ABC, first with the print command, and second
with the echo command. Result:
ABCABCABCsnip
print (10): 0.085
ABCABCABCsnip
echo (10): 0.076
It's not a lot, but since we are displaying data a lot, (most used

This has been covered before. The difference actually depends on how
you're using it, rather than whether you use print or echo. For example,
your benchmark shows echo to be slightly faster, but the the following
script that I wrote last time this came up shows the opposite. The only
difference is that you're outputting a literal whereas I'm printing a
variable.
http://dev.stut.net/phpspeed/
At the end of the day there are more important things to worry about,
especially when you're talking in the region of 0.009 seconds per
100,000 calls it's not going to make anywhere near a significant
difference to any script you write, even really really big ones scripts.
To put it another way, you would need to make 10,000,000 calls for it to
extend the runtime of your script by 1 second. Granted you might have a
script that calls it 1000 times, meaning 10,000 requests to that script
would waste 1 second. But unless you're getting twitter-like levels of
traffic (they spike at over 11k hits a second) it's not worth worrying
about, and I'm guessing (hoping) their devs probably wouldn't care either.
Get over it and concentrate on the functionality and usability of your
code rather than insignificant details like this.

I've learned (not only from this) that whatever you do in PHP is fast,
and that you don't need to optimize your code for speed. Unless you're
hitting 100k+ hits per hour. But even then it would only save you
maybe one hour per year.

I wouldn't go that far. It is definitely possible to write horribly

But what else would you use a lot in your code?
all commonly used things (like while, if, echo, etc) are just (nearly)
as fast as their alternatives (for, print, etc).
Other functions (like file/stream) might be some performance
difference, but you probably use this only a few times in your script.
So there's not a bigger performance difference then when optimizing

Optimising is not useless, and I've never said it is. However, you have to do so where it's going to have the biggest impact. What I'm basically saying is you should be optimising logic before even thinking about whether you're using the most optimised functions. Are you sure that your code doesn't do anything it doesn't need to? Do you do a whole load of initialisation for each request that could be cached in some way? Is every part of that initialisation needed for every page request, or should it be doing different things on different pages.

!-- HERE ARE THE ENTITIES --

!--ENTITIES ABOVE!--
Of all the possible methods, entities are the easiest for bots to
handle. They just need to decode the entities.
in the past I found the following to be annoying enough for harvesters not to
bother:
function obsfucateString($str)
{
$ret = '';
for ($i=0;$istrlen($str);++$i)
$ret.= (mt_rand(0,1) ? '#x'.sprintf(%X,ord($str{$i})) :
'#'.ord($str{$i})).';';
return $ret;
}
no idea if it's still even remotely useful.
More reliable methods involve using javascript to write out the mailto:
tag. Do it in several statements. But even then, some of the smarter
spiders will execute simple javascript like that. You can make it better
by using onload to execute the javascript which means the spider will
need to implement that, which I don't believe they do at the moment.
Of course the best way is to use an image and don't link it. If it's
just a way for visitors to contact you, use a contact form. You don't
expose the email address and can control it a lot better.

Could I dynamically create a flash image, input the email and tell the flash image to mailto:[EMAIL PROTECTED] Do anyone have a solution?

But I see many problems, including: 1) How do I avoid echoing the email address in the a href= tag? 2) How would I write a png that would be long and high enough? 3) How would the same script display the png? You could obfuscate the address with html encoding, such as: @ - #64; in the HTML @ - %40 in the URL I believe the scrapers/spammers are still not bothering to defeat this trivial exercise because they still get a million hits looking for plain old emails. In short, I can't see far enough how to do this and avoid spider-raking in the HTML or header the content of the image. I would suspect that every email is tied to some database record, like an ID. Provide a FORM which has only the ID in it, and lookup the email, and send the email out yourself from your own server. Yes, you could end up sending a LOT of email. Or not, since you now control the sending with PHP and can refuse to send in whatever scenario you find unacceptable. For example, one of my sites does this but won't send more than 4 emails from any given IP address in one 24-hour period. So a scraper/spammer would need to alter their IP every 4 POST operations, which is really more work than they'll put into it. On a super busy server with millions of users or millions of potential recipients, this would probably be a big deal... On MOST websites, you'll essentially be playing postman for a couple legit emails a day, at most, and not having any problem with scrapers/spammers. -- Some people have a gift link here.

Hopefully that works?

But even then, some of the smarter spiders will execute simple javascript like that. You can make it better by using onload to execute the javascript which means the spider will need to implement that, which I don't believe they do at the moment. Of course the best way is to use an image and don't link it. If it's just a way for visitors to contact you, use a contact form.

One thing that might help you guys... now and in in the future are the
functions var_dump() and print_r(). You can wrap these with pre/pre
tags to make it all pretty and formatted for reading too.
If you're unsure of what exactly is happening with your data try this:
$colors = array('white'='#ff','black'='#00','blue'='#ff');
print_r($colors);
... and you will see:
Array ( [white] = #ff [black] = #00 [blue] = #ff )
So you would call $colors['black'] to access #00.

I get nothing
do you get something different?

What happens when you echo $colors[1]?

Re: [PHP] Echo a value from an arrays position
Nope... dead air. Of course getting an indexed value into an associative array seems a bit odd to me... maybe Jonas could shed some light on why he would go this route...

Re: [PHP] Echo a value from an arrays position
This may clarify - in php, integer and associate arrays are created
arbitrarily, ie keys can be numbers or strings. So, either create an array
like this:
array('1' = 'first element',
'2' = 'second element');
and call by the key!

Is there any way to call for an element value in an array by the position?
Like position 2 in the array and not the key name.

I think you're correct. This is because PHP arrays are a mash-up
(as Jochem put it) of numerical indexes/hashtables/assoc.
arrays/etc
Example:
[php]
$jonas = array('color' = 'blue', 'number' = 'three');
echo $jonas[1]; // prints nothing
$jonas = array('color' = 'blue', 'number' = 'three', 1 = 'readme');
echo $jonas[1]; // prints 'readme', even though it's technically
the third element
[/php]
So, your solution might be to first pull all of the array values out
into a new array, like this:
[php]
$jonas = array('color' = 'blue', 'number' = 'three', 1 = 'readme');
$jonas_new = array_values($jonas);
echo $jonas_new[1]; // prints 'three', as you'd hoped
[/php]
p.s. Bonus: If you wanted to get the keys out, use array_keys()
And yes, as Jay said, RTFM. It's very very helpful.
HTH,
