The thing is, is_numeric() will not check if a string is a valid int,
but any valid number, including a float.
For something like this, wouldn't a regex be better?
if(preg_match('/^\-?\d+$/', $string))
echo int

Nope, because the OP wants to test if a variable, that is a string,
could be converted to an integer. Not if a variable is an integer.

That is so about is_numeric(), but once I know it's a numeric, coercing it
to just an int is easy. *Validating*, rather than just assuring, that a
string is an integer is another matter; if you need to give feedback to the
user, etc., in which case a Regex is better.
(One small nit, + is possible on integers, too.)

>(One small nit, + is possible on integers, too.)
The op wasn't about casting a string to an int but detecting if a string was
just a string representation of an int. Hence using a regex to determine that.
Regular expressions are not just about giving feedback to the user.

I suppose one could try something like this:
if (is_string($val) && $val === (string)(int)$val) ....
If $val is an integer masquerading as a string, it should be identical to
the original string when cast back to a string, shouldn't it? (I can't try
it right now.)

Guess regex are the only useful solution here. When you consider to use
built-in functions, just remember, that for example '0xAF' is an integer
too, but '42.00' isn't.

It is semantically equivalent to
$val == (int) $val
and as far as I remember (I didn't read everything completely) this were
mentioned. I didn't read, whether or not, it was accepted as solution ;)

Not quite. That method will massage both values to the same type for the
comparison. Whoever shot it down said they both go to int. If that's the
case,
if ($val == (int)$val)
is more like saying
if ((int)$val === (int)$val)
What I suggested converts the string to an int, the resulting int back to a
string, then does a type-specific comparison to the original string value.

Shoot...I hadn't considered how PHP might handle hex or octal strings when
casting to int. (Again, not in front of a computer where I can test it
right now. )
Regexes have problems with more than 9 digits for 32-bit ints. I guess to
some degree it depends on how likely you are to experience values that
large.

Sebastian,
This is not true. $val === (string)(int)$val will do a string compare,
where as $val == (int) $val will do an integer compare, which will convert
the left hand to integer too. Your equation will always evaluate as true.
Andrews' solution should work too, but it depends on what you accept as
integer, in this case you would be able to parse normal numbers, with
optionally a sign and extra 0's in front.
is_numeric will parse those integers, but also hexadecimal, octal and
binary notations, and parses floating point integers. If you don't want the
floating points, you could add an extra check that verifies it is not a
float.

For Linux I quite like KATE, it's part of the KDE stuff. Netbeans is
great as a full-blown IDE, or Geany is quite nice if you need something
in-between those two. The great thing is that they are all available on
Windows too.

Since we're doing this, lemme toss in my rec for Sublime Text 2.
But I'm still holding onto my dear old Emacs, cos it's my frenz.

I've been playing with bluefish as of late. The openoffice folks have taken

Not really.
You script is web accessible right? It just opens a file and delivers it
to the browser of your visitor. It's easy to make a script that pretends
to be a browser and make the same request of your script to grab the
file.

Hi,

right after connecting to the database.
In my whole code I have used the commit method only once.
Between beginTransaction and commit methods, as far as I know, I did not

only an exec method of PDO, and an execute of PDOStatement. Maybe one of
these activated auto-commit?
And what are the possible commands which are able to activate auto-commit?
I know that the commit method can do that, but - as I already wrote - I
have issued it only once, and it is in the destructor of a singleton class.
So what could be the problem?
You don't say which database you are trying to access. Not all actually support
transactions, and some need a connection correctly set.

Although maybe there's something ascetic about going through features
