[PHP] Cannot Redeclare Function
Hello,
My function to read a comma separated text file and return a sorted multi-dimensional
array will not work if used more than once per page.
I know why I'm having this problem. But, I don't know how to solve it. :-(
Calling it Twice:
$services = tbl2array ("../locations/service.txt", "default", $divdetail['id'], "0");
$collections = tbl2array ("../download/collection.txt", "name", $divdetail['id'], "4");
The Error:
Fatal error: Cannot redeclare compname() in ../tbl2array.inc on line 35
Function Table 2 Array:

[PHP] usort will not take variable
Hello,
Do you know the answer to this got'tcha? I want to call usort with a variable function
name. Basically, I want usort to sort any field I specify. Currently, I'm stuck
declaring a pile of functions and calling usort from if/elseif statements. :-(
Current:
function compname ($a, $b) {
return strcmp ($a["name"], $b["name"]);
}
function comptitle ($a, $b) {
return strcmp ($a["title"], $b["title"]);
}
function compcity ($a, $b) {
return strcmp ($a["city"], $b["city"]);
}
function compdesc ($a, $b) {
return strcmp ($a["description"], $b["description"]);
}
function compfile ($a, $b) {
return strcmp ($a["filename"], $b["filename"]);
}
if ($sortby == "name") {
usort ($result, "compname");
}
elseif ($sortby == "title") {
usort ($result, "comptitle");
}
elseif ($sortby == "city") {
usort ($result, "compcity");
}
elseif ($sortby == "description") {
usort ($result, "compdesc");
}
elseif ($sortby == "filename") {
usort ($result, "compfile");
}
What Works in Theory:
function mysort ($a, $b, $c) {
return strcmp ($a["$c"], $b["$c"]);
}
usort ($result, "$mysort, $sortby");
...but, that chokes.
Your help appreciated. :-)

[PHP] Validating E-mail Accounts
Is it possible, or (even better) do you have a sample script that can take a user-submitted e-mail address, contact the host, and verify that the account exists? Thanks, Rob
[PHP] Browser Sniff (Code Review Encouraged)
Hello,
Below is code I hacked up to read a user agent string (i.e. Mozilla/5.0 (Windows; U;
Windows NT 5.0; en-US; rv:0.9.8) Gecko/20020204
) and return several items including:
- the browser name,
- the browser version,
- the browser's major version number, and
- user definable compatibility listings.
This post is attached so that others may benefit. DISCLAIMER: I've been working with
PHP for a few months... about as long as I've ever been programming - feel free to
trust my brain at your own risk. Your thoughts and suggestions are welcome. :-)
ASSUMING CORRECTIONS ARE MADE DUE TO MAILING-LIST COMMENTS, I WILL REPOST THIS CODE.
Cheers, Rob
P.S. Is this the correct forum for tossing code around?
Now for the code...
WEB PAGE: (*.php ) <-- I removed all the HTML for readability.
REQUIRED FILE: (sniff.inc )
$name , 'version' => $version, 'major' => $major,
'raw' => $ua );
}
?>
REQUIRED FILE: (ua.inc )

4 => "true",
5 => "true",
6 => "true"
),
"Netscape" => array (
4 => "true",
6 => "true"
),
"Opera" => array (
5 => "true",
6 => "true"
),
"Mozilla" => array (

);
if ($uaarray[$name][$major]) {
return "1";
}
}

[PHP] Adding Dates (To Obtain Future Dates)
This problem took a while to figure out. I'm posting the solution so that =
other's may find this example. If you know of a better way, please reply. =
:-)
Cheers,
Rob
Problem: Generate Future Dates:
Sub-Problem: Future Dates are Dictated by Record Type (Permanent or =
Temporary)
The Script:
$cyear =3D date("Y");
$cmonth =3D date("m");
$cday =3D date("d");
if ($sType =3D=3D p)
{
$fyear =3D $cyear + 6
$sExpiry =3D $fyear.$cmonth.$cday;
}
else
{
$adv =3D $cmonth + 6;
$newunix =3D mktime(0,0,0,$adv,$cmonth,$cyear);
$sExpiry =3D date("Ymd", $newunix);
}
$sCreated =3D date("Ymd");
$sUpdated =3D date("Ymd");
It seems weird to have use months possibly greater than 12 ($adv =3D =
$cmonth + 6;), but hey... it works.

[PHP] PDF Library Not Working (Call to undefined function)
I RTFM but did not find a solution. My head hurts from banging it against = the wall. :-P Apache, OpenSSL, MySQL and PHP work fine... but the PDF libraries will not = work. I used the following configure commands: PHP: './configure' '--with-mysql=3D/usr/local/mysql/' '--with-xml' = '--with-apache=3D../apache_1.3.22/' '--with-curl=3D/usr/local/curl' = '--enable-shared-pdflib' '--enable-track-vars' PDFLib: Almost defaults... just turned off Python and C/C++. I can provide a complete list of configure options and the order they were = executed if you need them... The error message when attempting to use the PDFLib functions is: Fatal error: Call to undefined function: pdf_new() in /usr/local/apache/htd= ocs/program/dmipps/pdfdemo.php on line 2 Thanks for any help, it's really appreciated.

[PHP] Stripping Unwanted Characters
I'm posting this (see below) for two reasons: 1. so that others may benefit, and 2. to invite feedback on my code (PHP is the first language I have learned... and I've only been doing this for a week or so). Cheers, Rob P.S. Has anyone found a good way to parse variables to validate specific formats? For example: Canadian postal codes (ZIP codes) are like A1A-1A1. Driver's Licences are A123456789. Problem: Unwanted characters are often added by users of web based forms. This causes problems when storing the data, especially given the constraints of a database such as MySQL. Solution: Evaluate each variable, character by character, and (if true) add it to a new variable which may be used. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
