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.<test>.text
In fact it ends up being:
t<his.>is.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.
Cheers

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.
Bye

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

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.

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

OK. So what would be a good way to validate a date?

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;
}
}

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,

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.

It'd be great if you provided the output you are getting.

After cleaning up the code (I think the mail system might have stuck
in some weird characters, this is what I got:
<?php
error_reporting(-1);
ini_set('display_errors',true);
ini_set('display_startup_errors',true);
class TestClass {
public $a=20;
public $b=10;
public function TestClass($a= null, $b=null) {
if (!is_null($a))
{
$this->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:
<?php
error_reporting(-1);
ini_set('display_errors',true);
ini_set('display_startup_errors',true);
class TestClass {
var $a=20;
var $b=10;
function TestClass($a= null, $b=null) {
if (!is_null($a))
{
$this->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();
?>

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
<?php
$pid = pcntl_fork();
if ($pid == -1) {
die('Fork failed!');
} else if($pid > 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.

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.

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.

Err, what has this got to do with PHP?!?

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. :-) :-)

"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. I think I've been staring at ColdFusion code for too long;
I've gone all peculiar!
