What type is that variable?
Don't have to do a dump, I know its a tinyint(1), not null, default 0
PHP does not have a type of tinyint
knowing now that this comes from a database, if it is mysql, then it is of type
string
PHP converts all fields when pulled from the database into strings. It does not take into account
what type the field is actually set to in mysql.
Try puting a (int) in front of the condition like this
if ( (int)$userValues['afterDark'] == 0 ) {
...
}
Maybe this will help
That would be the type in the database, not the type of that variable at
that time.

Hi!
Phil:
Still I am curious what var_dump($userValues['afterDark']); at line 102.5
would return.
I managed to recreate that fault with
$var['test'] = "blah";
echo ($var['test']);
if( $var['test'] == 0)
{
echo "ok";
}
//this returns blahok -- not expected.
In my case Var_dump() returns string(4) "blah" as expected.
Using
if( $var['test'] === 0)
behaves as expected!!
Jim:
TypeCasting would only be effective if you used the type sensitive
comparison operator === , because with "==" 0 equals NULL equals false
equals "" and so on ... or do I miss something here??
Hope that solves it for you! I'm still investigating why my first examples
fails. I've got the strong feeling that I'm missing something there. I don't
believe in a php bug or a memory leak in this case! Must be something pretty
obvious! Anyone a clue??
Thanks,
Jan

Are you wanting to only test for a empty/non-empty string?
if so, use this.
if ( empty($var['test']) ) {
echo "var['test'] is empty";
}

Hi!
Thank you for your response!
The only intention of my code was to investigate the (back then) unexpected
behavior of the if statement.
With $var['test'] set to "blah" this expression should be false
($var['test'] == 0) for what I know ...
$var['test'] = "blah";
var_dump($var['test'] == 0);
//returns bool(true)
Now I know why this happens! According to Table 6.5 of the Operators page in
the PHP Manual in this comparison all of the values are converted to
integer. And atoi("blah") for sure will fail!;-) So you have to use === to
keep the types of the values!

Absolutely right. didn't think of that.
var_dump($userValues['afterDark']); ==> string(1) "1"
but then I'm comparing a string to an int and the result always seems
to pass. So does that mean any string compared to any int will be true?
By casting (int)$userValues['afterDark'] the test still passes and
var_dump shows the (int)$userValues['afterDark'] as an int(1) but
does give a value like the previous example.
ie. string(1)"1" but only int(1) Not sure if the expression has a
value of "1" now that its been cast.
Then finally if ( (int)$userValues['afterDark'] === 0 ) { //
passes
So:
if ( $userValues['afterDark'] == 0 ) { // passes
if ( (int)$userValues['afterDark'] == 0 ) { // passes
if ( (int)$userValues['afterDark'] === 0 ) { // passes
And the value of afterdark in the mysql table is tinyint(1) 1.
And echo( 1+(int)$userValues['afterDark']); // outputs 2
Now I'm confused!

Ummh, no!
(int) and (integer) perform a C style atoi() conversion.
(int)"blah" => integer 0
(int)"" => integer 0
(int)"1" => integer 1
(int)"12" => integer 12
("1" == 0) => false
("blah" == 0) => true
( (int)$userValues['afterDark'] === 0 ) only is true, if
$userValues['afterDark'] is a string not containing an integer. This is what
happens:
$userValues['afterDark'] gets converted to integer by atoi(), and after that
is compared by type and value to integer 0. So the type part of the test
will pass for sure.
But perhaps you should try to adapt the comparison to the DB value. So try
($userValues['afterDark'] == (string)0)
This expression is only true if $userValues['afterDark'] equals "0", not
when $userValues['afterDark'] equals "" or "blah" or "1"
Hope that helps!

Sounds like an architectural issue to me. Think about why you want to do
this. Can you not just include the other script rather than causing
another HTTP request?
I could do something complicated and store the $_POST vars in $_SESSION[],
but what I'd rather do is simply add a var to $_POST[] and resubmit this to
the same .php.
Let me get this straight... you want to add a variable to the $_POST
array and then re-run the current script? Put the functionality you need
into a function and then use standard control structures (while, if,
foreach, etc) to call it over and over again if necessary. There's
absolutely no need to cause another HTTP request.
Is their any way to do this, or do I need to rethink things?
Rethink things. There's almost certainly a better way but without
knowing why you think you need to do this it's not possible to help any
further.

Session variables is a decent way.
Storing them in a DB session can be good too
It all depends on the data.
The dumbest (but still correct) way to do it is a for() loop that
creates a hidden input with the name/value pair for each variables you
want.
I would advise against resending the username/password over and over.

Put the processing in a function, run the post variables through the
function. Create another array to hold the post variables and add
another variable and send that array to the function.

There's nothing complicated about using sessions.

You can do either one, Tony --- rethink or go ahead with it.
Check out the cURL functions if you want to forward the variables
as a POST to a different script. Otherwise, if you're just trying to
add new values to the $_POST array to be processed further down the
script, simply add them.
<?
$_POST['new_name'] = "new value";

this data is supposedly clean, some would say that it is best to assume that the data is might be
tainted, but I have always assumed that nobody is actually going to modify the session data files
directly and inject harmful data into the session file itself.
But some would say, even re-clean the data that you pull from your sessions, because you never know
how someone might try and mess with you.

Subject: [PHP] ADODB Insert Question (Syntax)
Hi
What is the proper way to get the ADODB class to automatically add
quotes to the below sql ?
I'm guessing that the below fails because none of the variables get
quoted with the method, qstr.
$sql = "insert into email (to_name, to_email, from_name, from_email,
subject, message, timestamp, ip) ";
$sql .= "values ($to_name, $to_email, $from_name, $from_email,
$subject, $message, $time, $ip)";
I tried something like the below to no avail
$sql .= "values($conn->qstr($to_name), $conn->qstr
($to_email), .......)";
Is there an accepted way to place multiple $variables inside an ADODB
insert statement?
many thanks

Okay, I'm probably missing something, but why can't the values portion
just
say:
"values ('$to_name', '$to_email', '$from_name',... etc.
hold on now. you might want to make sure and escape data before you just throw it into the query
like that.
His method was just fine, but the problem is is that the $obj->method() thing wont work in a quoted
string.
If he had E_NOTICE turned on, he would see the error.
what needs to happen is that he needs to break out of the double quotes and concat the string(s) and
method calls together like this.
$sql .= "values(".$conn->qstr($to_name).", ".$conn->qstr($to_email).",
.......)";
... with the single quotes around the variable names?

I've written one myself. It allows for job seekers to put up a profile,
resumes, etc and for employers to post their jobs and search resumes.
Full search ability on both sides. They can even opt for "Hot Resumes"
or "Hot Jobs" for higher/preferred listings in the search.
I'm not sure what else is really out there. I guess it will all depend
on what you're looking to do.

Does php have a facility similar to python's stringIO?
What I'm wanting to do is similar to a mail merge. IOW, I know I can
create an include file like:
$out = <<<EOT
This is an example of $var1 and $var2.
EOT;
and then after assigning values to $var1 and $var2 include that file. I
can later use different values for $var1 and $var2 and get a different
$out with a second include.
Can I someout "include" a string instead of a file? Or maybe there is
some completely different way to do what I want.

template.php
<?php
ob_start();
echo "Hi, my name is {$first_name} {$last_name}.";
return ob_get_clean();
?>
This is two different ways you can do it, bases on your input data array
structure
test.php
<?php
$values = array();
$values[] = array('first_name' => 'Jim','last_name' => 'Lucas');
$values[] = array('first_name' => 'James','last_name' => 'Lucas');
$values[] = array('first_name' => 'Jimmy','last_name' => 'Lucas');
foreach ($values AS $row) {
extract($row);
echo include 'template.php';
}
$values = array();
$values[] = array('Jim','Lucas');
$values[] = array('James','Lucas');
$values[] = array('Jimmy','Lucas');
list($first_name, $last_name) = current($values);
do {
echo include 'template.php';
} while (list($first_name, $last_name) = next($values));
?>

I know this isn't exactly a php related question but due to the
quality of answers ive seen lately ill give this a shot. (yes yes im
smoothing up the crowd before the question)
I have a weblog system that i am creating, the trouble is that if a
user links to an external image larger than 500pixels in width, it
messes with the whole layout.
I had found some regex code im using atm but its not good at matching
the entire image tag. It seems to ignore properties after the src
declaration and not match tags that have properties before the src
declaration .
preg_match_all("/\< *[img][^\>]*[src] *= *[\"\']{0,1}([^\"\'\ >]*)/i",
$data, $matches);
print_r($matches);
This currently makes two arrays for me, the source location from all
img tags and a large part of the tag itself. But not the entire tag.
What i do is i match the img tag, find the src, get the image
properties, and if the width is more than 500, i shrink it down and
add width="X" and height="Y" properties to the image tag.
How can i match an image tag correctly so it does not cause any issues
with how the user adds the image.

<style>
#your_content_div img { max-width: 500px !important; }
</style>
OK, so it won't work with IE6. Screw them.
But if the height is set in the img tag it'll keep that, so the image
could become distorted. So, you could also do something like:
#your_content_div img { visibility: none; }
Then run some Javascript routine onload to properly figure the
dimensions of each image. Adjust the width down to 500px, if necessary,
then the height by whatever percent difference between original width
over new width:
var new_height = (original_width / 500) * original_height;
Then, whether you change the dimensions of the image or not, change the
visibility of each to 'visible'.
So, um ... no PHP involved.

Maybe this is what you are searching for:
$images = array();
$data = "blah <img src=img.png width=\"400\" height='600'> src=blah.png <img
src=gg.tiff>";
preg_match_all("/\< *[img][^\>]*[.]*\>/i", $data, $matches);
foreach($matches[0] as $match)
{
preg_match_all("/(src|height|width)*= *[\"\']{0,1}([^\"\'\ \>]*)/i",
$match, $m);
$images[] = array_combine($m[1],$m[2]);
}
print_r($image);
It will produce:
Array
(
[0] => Array
(
[src] => img.png
[width] => 400
[height] => 600
)
[1] => Array
(
[src] => gg.tiff
)
)
I wrote it just as an example. So you may modify it for your needs!
Does anyone know if there is a way to put this into ONE regex??

I've done that on occasion, but do be careful what you are sending via
the GET.
It has a size limit for one (maybe 1k chars?) and it is trivial for
someone to modify.
I generally use GET when I think it's a page "setup" the user may wish
to bookmark (ie: page.php?orderby=name&descending=1&report=69 )
And POST for submitting data that I want to save. (ie: add a new user
and all their glory).
I have done a mixture, such as page.php?action=delete&id=5
But you have to be careful. I guess I always have some kind of user
class and verify they have permissions to use the page and or delete
said record anyways (logging failed attempts of course).

I have a question about including php files that are outside of

Here is the situation:
I want to store sensitive data such as login/pw data for

rwx for user nobody (FreeBSD) only. So no ftp access,
no mortal user access, etc. Is it possible to do this in
this situation? Would the Parent Apache process use
its privileges to include a file of this type?
I have texts and other data about storing data out side
the document root, but none go into it in this detail?
Apache runs as the "User" setting in httpd.conf
If that "User" can rwx the files, then PHP can rwx the files.
If not, not.
It's that simple.
Thanks, so if I make the directory and file outside of the document
root owner noboby with rwx for owner only, that will work?

Re-indent your code properly. If you do it will look like:
<?php
$pattern = ".html*|.php*";
if (is_dir("files/")) {
if ($dh = opendir("files/")) {
echo "<select name=\"file\" size=\"8\">";
while (($file = readdir($dh)) !== false) {
if (ereg($pattern, $file))
if(strpos($file,'.')>0) {
$file_array = array($file);
sort ($file_array);
foreach($file_array as $key => $value) {
echo "<option value=\"$value\">".$value."</option>";
}
}
}
echo "</select>";
closedir($dh);
}
}
?>
You have a number of things you need to look at here. First, you don't have a final
closing brace for your opening if() statement. Second, you're outputting the
<option> tags INSIDE the while loop that reads the directory, so for every file
you read your options list will get bigger. Well, it would, but you're also not using
the right array append method; it should be:
$file_array[] = $file;
Next, you don't want to sort the array every time you add a file to it - just
do it once when you're done.
Try this:
<?php
$pattern = ".html*|.php*";
if (is_dir("files/") && $dh = opendir("files/")) {
echo '<select name="file" size="8">';
while (($file = readdir($dh)) !== false) {
if (!ereg($pattern, $file)) continue;
if(strpos($file,'.')<1) continue;
$file_array[] = $file;
}
sort ($file_array);
foreach($file_array as $value) {
echo '<option value="' . $value . '">' . $value . '</option>';
}
echo "</select>";
closedir($dh);
}
?>
Syntax check is left as an exe3rcise for the student. =)
