[PHP] preg_replace and eval
Hey there,
We have a class that sets up a tree structure that represents an e-learning
object made up of nested "components". We have a function
getPropertyValue($name) which returns the property $name for the current
component.
Now, we want to allow the user to use something like {parent.property} in a
property value, so that it can inherit parts of properties from the parent
component. For example: caption = "the name of this component's parent is
{parent.name}!"
The following line sort of works:
$retVal =
preg_replace("/(.*){parent.(.*)}(.*)/e","'\\1'.\$this->parentNode->getProper
tyValue('\\2').'\\3'",$retVal);
However, if there are more than one string to replace it only works on the
last one. So:
caption = "the parent's coordinates are ({parent.left}, {parent.top})" would
only return something like: "the parent's coordinates are ({parent.left},
100)"
Hope someone can help.
Thanks
Dan

[PHP] Stripping illegal characters out of an XML document
Hi there. I'm working with RDF/XML that is strict on what characters are allowed within the elements and attributes. I was wondering if anyone had a script that processed a string and replaced all illegal-characters with their HTML code, for example "&" is converted to & and " to ". It should also work for characters like "é". It would be possible to process the strings before they are inserted into the XML document - if that is easier. If there isn't a script that'll do this I'll have to write my own - which could be quite time consuming ;( Thanks Dan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Stripping illegal characters out of an XML document
Thanks, I've created a delimited file of all the HTML Character references.
I then loop through and do a replace as previously suggested. However,
IE's XML Parser still doesn't like the é which represents é
For all intents and purposes it's ok and works with the RDF processor.
However, I'd like IE to be able to view the XML file just for completeness.

Re: [PHP] How can i resize images after upload?
Why not use PHP's built in image library: http://www.php.net/manual/en/ref.image.php -- it's pretty cool. The resample function doesn't exist in some old install but it's quite easy to write your own -- just doesn't run as fast as a compiled version.

[PHP] What do you say to someone who says...
What do you say to someone who says: "PHP is just a kiddie language"? (Source: http://www.dhtmlcentral.com/forums/topic.asp?TOPIC_ID=19373) PHP is currently my strongest development language and it annoys me that it is a much less bankable skillset than .NET and Java.

[PHP] Re: Starting OOP
It would be a good idea to create a database abstaction class. This means
that should you move your application to a different database you only have
to replace your database class, instead of recoding everything with the new
set of functions. It can also be neater than using the mysql functions
directly.
You could use it as in a composite or an aggregated relationship. Check out
http://www.phppatterns.com/index.php/article/articleview/15/1/1/ for some
useful information.
Also is it necessary to have $ponum sent to each function, how about
creating an attrbute of the class and setting it in the constructor
function.

[PHP] Re: RewriteRule REGEX ?
I don't think you need to escape the full-stop (period) that could cause problems.

[PHP] Re: send a POST to a URL from within PHP code
You need to open a socket:
http://uk.php.net/manual/en/function.fsockopen.php
Think there's a demo in the comments lower down the page.
Yup, here it is:
function httpPost($host, $path, $referer, $data) {
$fp = fsockopen($host, 80);
fputs($fp, "POST ".$path." HTTP/1.0\r\n");
fputs($fp, "Host: ".$host."\r\n");
fputs($fh, "Referer: ".$referer."\r\n");
fputs($fp, "Content-type: application/x-www-url-encoded\r\n");
fputs($fp, "Content-length: ".strlen($data)."\r\n");
fputs($fp, "\r\n");
fputs($fp, $data."\r\n");
fputs($fp, "\r\n");
$tmp_headers = "";
while ($str = trim(fgets($fp, 4096)))
$tmp_headers .= $str."\n";
$tmp_body = "";
while (!feof($fp))
$tmp_body .= fgets($fp, 4096);
fclose($fp);
return $tmp_body;
}

Hi all,
I would like to simulate sending a form in POST to a specified URL through
PHP. I knwo how to do this from a HTML form :
http://url.com/query";>
blablabla
I would just like to simulate this because I have some processes that will
change the values of the form before sending it to the 'action' URL
With a GET, the fields would be included into the query strinbg, so this is
quite easy. What happens in a POST?
Any idea is welcome
Vincent

[PHP] Re: Create a zip archive from a folder
I have achieved this using the shell_exec() function: $cmd = "cd ".escapeshellarg($curdir).";zip -r9b . ".escapeshellarg($name)." *"; $result = shell_exec($cmd); This moved the shell into the current directory ($curdir), then creates a new zip file ($name) for the entire directory. I have noticed that shell_exec() has unexpected results with certain commands, i.e. if it fails you won't always get the same message that you'd get at the command prompt.
