[PHP] DateTime wierdness
Can someone explain to me this weierdness I see when using the
DateTime module of PHP.
Here I send 14/14/2012 which is not a valid date, and I would expect
to recieve false, but instead, it looks like it wrapping to the next
year, as if 14 monthas are 1 year and 2 months. That isn't what's
supposed to happen, or is it?
$ echo " "|php
object(DateTime)#1 (3) {
["date"]=>
string(19) "2013-02-14 13:20:22"
["timezone_type"]=>
int(3)
["timezone"]=>
string(20) "America/Buenos_Aires"
}

[PHP] Watch out for automatic type casting
I found automatic typecasting can be a bit of a gotcha.
$sText = "this.is.a.test.text";
if ( $pos = strpos($sText, "test") !== FALSE) {
echo substr($sText, 0, $pos)."<".substr($sText, $pos,
strlen("test")).">".substr($sText, $pos+strlen("test"));
}
The code seems logical enough, and the expected result would be:
this.is.a..text
In fact it ends up being:
tis.a.test.text
The reason is $pos is typecast as TRUE, not int 10, presumably because it's
in the same scope as the boolean test.
Then when $pos is later used as an int it's converted from TRUE to 1.
You have to bracket the $pos setting to move it into its own scope to
prevent it being typecast:
if ( ($pos = strpos($sText, "test")) !== FALSE) {
No doubt it's mentioned somewhere in the php manual, I just never came
across it.
Just thought I'd highlight one of the gotchas of auto typecasting for any
other simpletons like me.

Re: [PHP] DateTime wierdness
echo date("m-d-y",mktime(0, 0, 0, 14, 14, 2012));
this outputs "02-14-13" also so my guess is that it is being interpreted
the same as "12/14/2012 +2 months"
echo date("m-d-y",mktime(0, 0, 0, 1, 45, 2012)); outputs
"02-14-12"
which is 1/1/12 +45 days

Re: [PHP] DateTime wierdness
OK. So what would be a good way to validate a date?

Re: [PHP] Watch out for automatic type casting
Hi, Arno
I don't know if this is written somewhere in the php-manual, but I
really like this table:
http://en.wikipedia.org/wiki/Order_of_operations#Programming_languages
I do not really understand why this has some special stuff to do with
typecasting ... This is just an order like the operators + and * in
math.
If you'd ask me, this is exactly what I would expect to happen.

Re: [PHP] DateTime wierdness
actually this would work well ... compare what they send with the output of
the formatdate
function checkDateTime($data) {
if (date('Y-m-d H:i:s', strtotime($data)) == $data) {
return true;
} else {
return false;
}

Re: [PHP] Watch out for automatic type casting
Hi, Arno
FYI: I found a page in the php-manual that's exactly for that:
http://www.php.net/manual/en/language.operators.precedence.php
p.s. some of them were also new to me Thanks for getting me to read it.

This is not due to typecasting, it's due to operator precedence.
In PHP (and many other languages) the !== comparison operator will get done
first, so the result of that comparison will be assigned to $pos. By
introducing the brackets you're explicitly specifying the order.
Details here: http://php.net/operators.precedence

Well, I did somethin similar...
$arDate = explode("/", $nacimiento);
if(!checkdate($arDate[1], $arDate[0], $arDate[2]))
$nacimiento = '';
Just need to set the variable $nacimiento to the empty string if it's
not a valid date.
Thanks anyway,

After cleaning up the code (I think the mail system might have stuck
in some weird characters, this is what I got:
a = $a;
}
if(!is_null($b))
{
$this->b=$b;
}
}
public function printAB() {
echo $this->a." ".$this->b."\n";
}
}
$inst1 = new TestClass(3,50);
$inst2 = new TestClass();
$inst1->printAB();
$inst2->printAB();
?>
Outputs:
3 50 20 10
as you expect. What is the question?

Crap, I didn't mean to send that. This is the actual code:
a = $a;
}
if(!is_null($b))
{
$this->b=$b;
}
}
function printAB() {
echo $this->a." ".$this->b."\n";
}
}
$inst1 = new TestClass(3,50);
$inst2 = new TestClass();
$inst1->printAB();
$inst2->printAB();

I don't know how it came to be, but a lot of people rely on this
behaviour. It does make sense if you squint at it a bit -- trust that
the programmer meant what they said and deliver something useful,
leave error checking up to the programmer. I'm a bit ambivalent about
it, personally, but the way it's implemented does seem more flexible.

Interestingly enough (again due to precedence + LR processing) if you
reverse the order of the test:
if (false !== $pos = strpos($sText, "test"))
it works! But I'm not sure it's a good idea to rely on that, as the
extra bracketing is probably more obvious to the reader.

[PHP] pcntl_fork behavior with php version 5.1.2
Hi,
i got some trouble with a PHP script using pcntl_fork do run some work in
background.
Runnig my script on my development system (PHP version 5.3.3-7) it behaves
like
intended. But running it on my production test system (PHP version PHP
5.1.2), i got
some strange results. The problem is, that when i logout from my SSH
session the
console closes not properly, like somethings is kept open. Sadly, updating
this old PHP
version is not a option... :/
Does anyone have an idea whats going on?
Thanks in advance
Ralf
The script is this:
#!/usr/bin/env php
0) {
exit(0); // close parent process
} else { // child process:
while(true) {
sleep(10);
// do your work -- stripped
}
}
?>

This sounds more like an OS issue then a PHP issue.
What are the two OSs involved?

You need to detach the child from the terminal using posix_setsid(). I don't
know why it's "working" on your development machine, but it's probably simply
that you're not seeing this issue due to how you access that development
machine.

Re: [PHP] pcntl_fork behavior with php version 5.1.2
I will try posix_setsid(). Both machines were accessed via a ssh client
(e.g. putty or ssh from a other linux box).
Thanks for your advice.

[PHP] Updating Google Plus
Anyone know a way to update Google Plus via the 33669 SMS number? Yes, I have seen the popular how-to instructions to get the secret email address by using Google Voice and forcing the error message, but I'd prefer a legit non-hack way to do it. I'd even be happy to pay for an SMS gateway rather than depend on the email address, which they might decide to terminate. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Updating Google Plus
Sorry, I did not mention the implied "using PHP". Since everything I do & eat & breathe is PHP, it didn't even occur to me to state the obvious. :-) :-) On Mar 29, 2012, at 2:46 PM, Stuart Dallas wrote: > Err, what has this got to do with PHP?!? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

"With PHP" is not a magic phrase that will make anything relevant for discussion on this list, but it's 2:10am and I'm feeling generous. So, to send an SMS message with PHP... * Use PHP to access the API for a commercial SMS gateway. There's loads of these, Google can find them for you. Each will likely have sample PHP code (the one I use, Clickatell does). * Install something like Kannel and use PHP to access its API. I dabbled with this a bit, but in terms of the cost of my time it was far cheaper to use a commercial gateway. * Use PHP to talk directly to a mobile phone through a serial interface. Ditto as far as the reason why I didn't go down this route. I tried it back in the late 90s and it was fun, but commercially speaking it was a waste of time. There's very little PHP involved here, and frankly Google could have given you these answers with very little effort on your part. Yeah, the generosity wore off :)* -Stuart * Smileys aren't magic either. Well, actually some are. Like the SMS you can send to an iPhone and it comes out looking like a whale - that's pretty magical and totally awesome.

Bye Simon Thanks Simon and others, thought it was typecasting, but precedence makes more sense. I remember seeing that table when I first started using php, which is why I always use AND and OR rather than && and || because it's lower precedence than the assignment and the ternary operators, but I couldn't remember where I'd seen it.
