Witango doesn't port easily, untll you build the framework to build
php code like witango does, using resultsets and array manipulation.
If you don't do that first, its very tough, and I can see the
frustration. Here is an example of a class function in php that takes
a mysqli connector and a string query, and returns an associative
array resultset, just like witango results set from a query, with
column names and all.
/**
* Query the database and return result set in an assoc. array
* @author Robert Garcia
* @param mysqli $myconn
* @param string $query
* @return array
*/
public function getResultSetFromConn($myconn,$query) {
$resultSet = array();
if ($myconn)
{
//now result is multidimensional assoc array.
if ($result = $myconn->query($query)) {
$fields = $result->fetch_fields();
while ($row = $result->fetch_array()) {
$thisRow = array();
foreach ($fields as $field){
$thisRow[$field->name] =
$row[$field->name];
}
$resultSet[] = $thisRow;
};
$result->close();
}
}
$temp = $myconn->errno;
$temp = $myconn->error;
return $resultSet;
}
Think of how many times you dump an array in witango to a table. How
do you do that in php, well, we build a function that takes IN a
resultset type array, and a boolean for header.
public function arrayToTable($inarray,$bool_header=true){
if (!count($inarray)){return "";}
$res = "";
$res = "<table border=1><tr>";
if ($bool_header){
foreach($inarray[0] as $key => $val){
$res .= "<td align=center><b>" . $key .
"</b></td>";
}
$res .= "</tr>";
}
$res .= "<tr>";
foreach($inarray as $rows){
foreach ($rows as $cols){
$res .= "<td>" . $cols . "</td>";
}
$res .= "</tr>";
}
$res .= "</table>";
return $res;
}
Here are the functions that we use that mimics the witango <@filter> tag
/**
* callback function for filter function
*
* @author Robert Garcia
* @param array $array
* @return array
*/
private function filter_thisarray($array){
$eval = "return ".$this->arrayeval.";";
$res = eval($eval);
return ($res);
}
/**
* Filter an array ($array = your passed in array, use it for the
callback expression)
* sample: $status = $global_app->filter($pcustArray,"\
$array['UserID'] == '".$inarray[0]['userId']."'");
*
* @author Robert Garcia
* @param array $array
* @param array $arrayeval
* @return array
*/
public function filter($array,$arrayeval){
$this->arrayeval = $arrayeval;
return
array_values(array_filter($array,array($this,"filter_thisarray")));
}
And the @distinct tag
/**
* Output a distinct array from input array based on fieldname entered
*
* @author Robert Garcia
* @param array $array
* @param string $fieldname
* @return array
*/
public function array_distinct($array, $fieldname)
{
foreach ($array as $sub)
$cmp[] = $sub[$fieldname];
$unique = array_unique($cmp);
foreach ($unique as $k => $rien)
$new[] = $array[$k];
return ($new);
}
So basically, I rolled up my sleeves and built all this, then we used
it to port. Porting goes much quicker this way, and allows you to
still code like you used to in witango. Then as you start new
projects, you still use some of these methods, and sometimes you do
whatever the heck you want, because PHP is so flexible.

I have started developing in PHP but find it very slow to develop
compared to witango. The old witango builder wizard worked for 80%
of our stuff and I really miss it in PHP.
Has anyone given much (any) thought to the concept of building your
app/site proof of concept in Tango for the ease and speed of
building the logical building blocks etc. And then once your FC is
working as you want then porting it to PHP. From way back when CF
was the big kid on the block I remember that the CF crowd came up
with an app paradigm called FUSE (or something) and that when we
looked at it it was basically a logic framework which mimic'd the
Tango app architecture. You would only have 1 page but in that page
was all the logical decisions on what to show the user based on the
URL and their user vars.
Anyway, it seems that if this was embraced by the developers then
someone on the list could make a nice biz of just porting apps to
PHP. The Tango developers could build the porting fee into their
original bid etc.
And finally for the sake of reality don't forget that the main
(perhaps only) reason that PHP is the defacto standard now was that
it was given away from the start and there is no way to effectively
compete with free. That's how IE pushed Netscape aside and now
NetNewsWire will push all the newsreader apps aside.
I laughed the other day when I saw the new decode for the acronym
PHP, I don't remember what it was but they are trying to make you
forget that PHP actually stands for "Personal Home Page".
