Re: [PHP] [PHP5RC3] echo $this-db-host not work
Try enclosing the variable in Curly Braces
echo {$this-db-host} ;
Otherwise, the string parser sees $this-db as the variable you're
referring to.

[PHP] Re: Running a PHP script on an automated regular schedule
You may also want to look at wget as a way of invoking your PHP script if command line support is not available. Henry I.A. Gray [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi.

Re: [PHP] Re: [Q] Why does my php file gets displayed instead of executed
Could it be that php files are not executed for POST method?
Michael T. Peterson wrote:
Per request, here are the two other source files that get executed prior to
the invocation of validate_member_login.php, index.php and init.php.
But first, here's a simple restatement of the problem:
(1) Direct the browser to open index.php
(2) init.php is included by index.php.
(3) index.php dispatches user to member_login.htm. User fills in username
and password fields and then presses the submit button.
(4) form action=validate_member_login.php .../ is invoked.
(5) The source code of validate_member_login.php is displayed in the browser
rather then being executed.
However, when the invocation sequence is:
(1) Direct the browser directly to member_login.htm and fill in the username
and password fields.
(2) Press submit.
(3) validate_member_login.php is executed properly.
Here's index.php. Its purpose is to check the session variables to
determine whether the user is logged in. If not, the user is dispatched to
member_login.php via redirct using header().
Now, here are the two php files of interest, index.php and init.php. First,
index.php,

$username = $HTTP_SESSION_VARS['username'];
$result = authenticate_session( $username, $session_id );

} else {

}
}
header( 'Location: '.MEMBER_HOME_PAGE );
}
header( 'Location: '.MEMBER_LOGIN_PAGE );

A note I forgot to addi in my previous posting:
You ought to think over what you consider empty since empty() would
for example return true if the checked variable contained the integer 0
or the string '0'.
My posted line of code recognizes only an empty string as empty.

[PHP] addslashes vs string unescape
I'm confronted with a somewhat weird problem and hopefully someone can make a
suggestion. I have to perform the following 3-step task:
Step 1. Someone provides a string (let's call it the formatting string) which
contains a PHP expression, which will apply a PHP function on another string,
let's call this one the random string. I don't control either the formatting
nor the random string.
Example of formatting string: trim('%val%')
Step 2. As you may have guessed, I have to insert the random string in the
formatting string before I can eval() the latter. So I need to replace %val%
with the random string. But I have to be careful, since the random string may
itself contain either double or single quotes, which will break the eval()
later. So I also need an addslashes().
Operations performed:
$for_eval=str_replace('%val%',addslashes($random),$format);
$for_eval='$final_result='.$for_eval.';';
eval($for_eval);
Step 3. After the above, I should have the formatted string in $final_result.
***
So now for the problem: addslashes() indiscriminately escapes with backslashes
both single and double quotes. Strings variables can be specified with either
single or double quotes; each of the cases, in turn, will not un-escape the
other type of quote. For example, a string enclosed in double quotes will not
un-escape \' and a string enclosed in single quotes will not un-escape \.
But my addslashes() escaped both types of quotes. And the formatting string
(see step 1) will necessarily have enclosed the string to be (%val%) in only
one of the two types of quotes. So, after all steps are performed, I may very
well be left with either single or double quotes still escaped, depending on
the type of quotes which were used in the formatting string.
I was under the impression that double quote strings will be interpreted as to
unescape single quotes too. However, the manual says they don't do that; they
unescape some common print sequences (such as tab or newline), double quotes
(of course), backslash itself, and octal or hexa expressions. NOT single quotes.
If only I could be sure of the type of quotes which were used in the
formatting string, I could only escape those by hand. But I can't be sure.
Also, I can't forcefully strip slashes from the final result, because I don't
know which sequences that look like escapes are really escapes or are just
legitimate pieces of string.
If only double quote strings would un-escape both types of quotes; they don't,
so their un-escape action is not a 100% reversion of the addslashes() effect.
Any ideas?

I'm not sure about MySQL, but I know for PostgreSQL when I prefix a

Try changing:
fputs($ap, $row['users.name']);
fputs($ap, $row['users.company']);
To:
fputs($ap, $row['name']);
fputs($ap, $row['company']);
That should do the trick.

suggestion. I have to perform the following 3-step task:
Step 1. Someone provides a string (let's call it the formatting string) which
contains a PHP expression, which will apply a PHP function on another string,
let's call this one the random string. I don't control either the formatting
nor the random string.
Example of formatting string: trim('%val%')
Step 2. As you may have guessed, I have to insert the random string in the
formatting string before I can eval() the latter. So I need to replace %val%
with the random string. But I have to be careful, since the random string may
itself contain either double or single quotes, which will break the eval()
later. So I also need an addslashes().
Operations performed:
$for_eval=str_replace('%val%',addslashes($random),$format);
$for_eval='$final_result='.$for_eval.';';
eval($for_eval);
Step 3. After the above, I should have the formatted string in $final_result.
***
So now for the problem: addslashes() indiscriminately escapes with backslashes
both single and double quotes. Strings variables can be specified with either
single or double quotes; each of the cases, in turn, will not un-escape the
other type of quote. For example, a string enclosed in double quotes will not
un-escape \' and a string enclosed in single quotes will not un-escape \.
But my addslashes() escaped both types of quotes. And the formatting string
(see step 1) will necessarily have enclosed the string to be (%val%) in only
one of the two types of quotes. So, after all steps are performed, I may very
well be left with either single or double quotes still escaped, depending on
the type of quotes which were used in the formatting string.
I was under the impression that double quote strings will be interpreted as to
unescape single quotes too. However, the manual says they don't do that; they
unescape some common print sequences (such as tab or newline), double quotes
(of course), backslash itself, and octal or hexa expressions. NOT single quotes.
If only I could be sure of the type of quotes which were used in the
formatting string, I could only escape those by hand. But I can't be sure.
Also, I can't forcefully strip slashes from the final result, because I don't
know which sequences that look like escapes are really escapes or are just
legitimate pieces of string.
If only double quote strings would un-escape both types of quotes; they don't,
so their un-escape action is not a 100% reversion of the addslashes() effect.
Any ideas?
Can you use this?
[code]
?php
// Formatting string from outside - apply a function on a random value
$format_string = 'trim();';
// Random value from outside - may contain quotes /-:
// Leading and trailing spaces for trim() included
$rand_string = eod
My name is Bla, I want to do some 'foo'.
eod;
// Before and after - remember string's original length
$strlen_start = strlen($rand_string);
// Replacing all single-quotes with double-quotes
$rand_string = str_replace(', '', $rand_string);
// Combine format string with random string
$for_eval = sprintf(
'%s%s);',
substr($format_string, 0, -2),
addslashes($rand_string)
);
// Save return value of format-random-combo in $final
$for_eval = sprintf('$final = %s', $for_eval);
// Dump and eval
printf('tt%s/tt', $for_eval);
eval($for_eval);
// Before and after - remember string's new length
$strlen_end = strlen($final);
// Results:
printf(
'brttbefore: %d, after: %d/tt',
$strlen_start, $strlen_end
);
?

[PHP] Trouble with arrays from within MySQL results where clause

I doubt the array is empty. It may not contain what you think it should,
though. Try using print_r() on $data as you run through the code so you
can see what it contains.
if ($sig1 -150) { $aval = $sig1; }
Don't put quotes around -150. As you have it right now, you're comparing
strings. If $sig1 is a number, PHP plays nice and assumes you mean
-150 instead of -150, though. Also, you don't need quotes around $sig1
at the end of the line.
if ($sig2 -150) { $bval = $sig2; } if ($bval $aval)
{$aval = bval;}
Missing a dollar sign for bval on this line, unless bval is really a
constant. Same deal with the quotes, too.
if ($sig3 -150) { $bval = $sig3; } if ($bval $aval)
{$aval = $bval;}
Same deal here with the quotes, also.
$data[] = array('$time' = '$time','$aval' = 'aval');
Variables in single quotes are not evaluated. '$val' is not the same as
$val. Either way, you don't need any quotes here (assuming you mean
$aval for the last entry.
$data[] = array($time=$time, $aval=$aval);
$aval = -999;
$aval = -999;
Again, $data has something in it so long as your query is running. It is
probably just not what you think it is.

How about array_filter()? From the docs: If the callback function is
not supplied, array_filter() will remove all the entries of input
that are equal to FALSE.
$a = array ('a' = 'foo', 'b' = '', 'c' = null, 'd' = 99, 'e' = 0);
print_r (array_filter ($a));
// Output:
Array
(
[a] = foo
[d] = 99
)
As a previous poster noted, though, this will only work for you if 0
and the empty string et al. are not significant in your application.

It seems to work, at first test, but it's somewhat convoluted. I've found
another fairly reasonable solution: using $val instead of %val%. This way I
don't need to ever show the actual contents of the random string in the
eval() and the problem becomes void.
I said fairly reasonable because it will still require a painful porting
period and letting people know they should move to $val, but in the long run
it will work. Here's a lesson about not testing well enough before deploying.
Thank you for the help just the same.
Assuming the formatting string is in $formatString and the random
string is in $randomString:
$evalStr = str_replace('%val%', '$randomString', $formatString);
$result = eval('return '.$evalStr);
No need to change the way that users format their format string.

[PHP] stripslashes() when reading from the DB
Hi,
I usually stripslashes() when I read the info from the database (MySQL).
Because the information was inserted after adding slashes, or the
system has magic_quotes_gpc set to ON.
I'd like to know, if I can do stripslashes() directly, as it is suposed
that all data was inserted into DB after slashing the vars. I mean,
should I check or not before if magic_quotes_gpc are on ?
As I know, magic_quotes_gpc has nothing to do with info readed from the
DB, as it only affects Get/Post/Cookie values.
I think to make a check like this:
$result = mysql_query(SELECT );
$row = mysql_fetch_assoc($result);
foreach ($row as $key = $value) {
$row[$key] = stripslashes($value);
}
But not sure if it really necessary, as i'm getting some confusing results.
Any help will be welcome
Regards,
Jordi.

do I use a cookie to record multiple values? Help would be appreciative.a
As the standard says, 1 cookie = 1 value, no way to have more than one
value in a cookie.
But you can think about some workarounds, a quick example just to give
you an idea:
$cookie = implode(':', $array)
Here you will have all values from the array in the cookie, and using :
as a separator.
To reverse the values: $values = explode(':', $cookie) and here you will
have all values in the array $values, starting with index 0.
Of course, in this way you can only set values, not the array keys. Look
in the manual for implode() and explode() and see if is usefull for you.

Jordi.

[PHP] OO woes
PHP version 5.0.0RC3 (cgi) (built: Jul 9 2004 13:18:24)
I'm just getting my feet wet with OO and have run into a problem that I'm
not familiar with...yet.
I have a class that does a database connection and query all together. It
all works nicely untiluntil my query has a word with quotes around it.
I've tried addslashes and mysql_escape_string but when I do I get a Fatal
Error. It occurs in the execute($query) function down below.
I'm also using the recommended php.ini file...magic quotes off and all.

protected $user; // Database username
protected $pass; // Database password
protected $dbhost;// Database host
protected $dbname;// Database name
protected $dbh; // Database handle

$this-user = $user;
$this-pass = $pass;
$this-dbhost = $dbhost;
$this-dbname = $dbname;
}

$this-dbh = mysql_connect($this-dbhost, $this-user, $this-pass);
if (!is_resource($this-dbh)) {
throw new Exception;
}

throw new Exception;
} elseif (!is_resource($ret)) {
return TRUE;
} else {

My query statement is:
$query = 'INSERT into aeMail set test=\''.$_POST[test].'\'';
I call the class as follows:
$dbh = new DB_Mysql(user,passwd,localhost,test);
$query = 'INSERT into aeMail set test=\''.$_POST[test].'\'';

If the $_POST variable does not contain any quotes, the class works
perfectly. But whenever quotes are passed through, I get the following

So how do I use a cookie to record multiple values? Help would be

A few options: use multiple cookies, e.g. setcookie('cookie_a'),
setcookie('cookie_b'), etc. Jordi's suggestion is also good, though I
would suggest using serialize() to make a single string out of your
values, like this: serialize(array('name1' = 'value', 'name2' =
'value'). Or, use PHP's built-in session support. The cookie stores a
unique ID, whie the actual values are stored on the server.

Your quotes look screwy to me. You seem to be missing both trailing single
quotes.
try this:

Re: [PHP] OO woes
Your problem has nothing to do with the Objects (or really even PHP for
that matter). You're not supposed to run mysql_escape_string on an
entire query. Here's an example of its usage:
$sString = This string contains a single-quote (');
$sQuery = INSERT INTO mytable SET
mystrcolumn='{$sString}',mynumbercolumn=24;
INSERT INTO mytable SET mystrcolumn='This string contains a
single-quote (')',mynumbercolumn=24 == $sQuery; // This just shows
what's in $sQuery
If you were to run $sQuery as it is, it would not parse because the
single-quote in $sString would indicate the end of that string, and the
characters following it aren't valid SQL.
But, if you were to use mysql_escape_string on $sString, before putting
it in the query, everything would work out fine.
$sString = This string contains a single-quote (');
$sString = mysql_escape_string($sString);
$sQuery = INSERT INTO mytable SET
mystrcolumn='{$sString}',mynumbercolumn=24;
INSERT INTO mytable SET mystrcolumn='This string contains a
single-quote (\')',mynumbercolumn=24 == $sQuery; // This just shows
what's in $sQuery
Now the single-quote in $sString has been escaped, and MySQL doesn't see
it as the string delimiter.
On a side note, mysql_real_escape_string would probably be prefferable,
as it takes into accoutnt he character set of the current connection.

Uncaught exceptions happen whenever you THROW an exception that isn't
caught. This allows you to do certain things when exceptions happen and
try to recover from the error. So, it should work when you try this:
try {
$dbh = new DB_Mysql(user,passwd,localhost,test);
$query = 'INSERT into aeMail set test=\''.$_POST[test].'\'';
$dbh-execute($query);
}
catch (Exception $e) {
// This just prints, but you could do other things like ignoring
// the error or trying to reconnect, etc.
echo $e-getMessage();
print_r( $e-getTrace() );
}
Nice, that makes it easier on the eyes to read.

Re: [PHP] stripslashes() when reading from the DB
I usually stripslashes() when I read the info from the database (MySQL).
Because the information was inserted after adding slashes, or the
system has magic_quotes_gpc set to ON.
I'd like to know, if I can do stripslashes() directly, as it is suposed
that all data was inserted into DB after slashing the vars. I mean,
should I check or not before if magic_quotes_gpc are on ?
As I know, magic_quotes_gpc has nothing to do with info readed from the
DB, as it only affects Get/Post/Cookie values.
I think to make a check like this:
$result = mysql_query(SELECT );
$row = mysql_fetch_assoc($result);
foreach ($row as $key = $value) {
$row[$key] = stripslashes($value);
}
But not sure if it really necessary, as i'm getting some confusing results.
What you *should* be doing is check for magic quotes when inserting into the DB.
if(!get_magic_quotes_gpc()) {
$value = mysql_real_escape_string($value);
}
$query = 'INSERT INTO table (field) VALUES ('.$value.')';
mysql_query($query);
To add further comment. If you're required to run stripslashes() on
data coming out of your database then you did something wrong. Your
code would have essentially looked like the following before insertion:
$var = addslashes(addslashes($var));
Where 'magic_quotes_gpc = on' essentially executed one of those
addslashes(). The above use of get_magic_quotes_gpc() shows you
how to add slashes just once thus not having a bunch of \' type
badness inside your database. Remember backslashes are only
added to make proper strings for db insertion so the backslashes
should never actually make it into the database.

Philip

I remember being taught this lesson long ago. :) You do not need to strip slashes from the data being read from the database. If you find yourself having to do that, then you're escaping the data twice before it's inserted. You more than likely have magic_quotes_gpc enabled which escapes all incoming GET, POST and COOKIE data and then you are running addslashes() yourself. You should check the magic_quotes setting with get_magic_quotes_gpc() and then determine if you need to use addslashes or mysql_real_escape_string(). -- ---John Holmes...

$a = array ('a' = 'foo', 'b' = '', 'c' = null, 'd' = 99, 'e' =
0);
print_r (array_filter ($a));
// Output:
Array
(
[a] = foo
[d] = 99
)
As a previous poster noted, though, this will only work for you if 0
and the empty string et al. are not significant in your application.
Nice idea Paul, will try it out :)
