If anyone is out there trying to make a website using PHP & MySQL and is stuck or confused about anything, we can post ITT and help each other through it.
An example would be even if you have an idea for a website that would make you $ but don't want to start because you are confused about site security, you would post that question here.
I'll start I guess by saying that i was recently hired at a web portal company so my PHP isn't very strong (which is why i'm making this thread) but then again if you know Java/C you know PHP...
Without revealing too much about the website, I have users who can save things about them so next time they log on they can see what they changed. My first try through this I used .txt (lol) with a format like this:
Code:
user:pref1,pref2,pref3
Used PHP's explode function to get the left side of the colon (group) and the right side was re-exploded by commas to get each pref in an array.
however obv. that wasn't going to last long and wasn't a longterm solution...so i've changed it to xml:
Code:
<group>
<username>test</username>
<prefs>pref1</prefs>
<prefs>pref2</prefs>
<prefs>pref3</prefs>
</group>
and i used PHP's SimpleXMLElement to retrieve the information, and that worked for displaying it.
However now i want to remove a node, and SimpleXMLElement doesn't remove nodes. After some google searching PHP's DOMDocument (used in php 5+, DOM XML was deprecated) was the thing i should use.
Not a lot of good documentation is on this however, and after a couple days i was able to display my information using the following code:
[PHP]
//load prefs.xml
$fileN = getUD($uID);
$fileN .= "prefs.xml";
//openDomXML is my function i wrote, just calls
//DOMDocument->load();
$prefList = openDomXML($fileN);
$prefList->getElementsByTagName("group");
echo "<pre>";
print_r($prefList->saveXML());
echo "</pre>";
[/PHP]
I guess "saveXML()" shows the text of the xml, but not the tags.
Has anyone used DOMDocument before? Any references/GOOD run throughs you want to point me to? I want to use the best O(n) code possible to make this work efficiently. The FIRST time i write it.
Thanks!
For those interested in website development (i am still struggling with CSS)
http://www.w3schools.com/ is a great place to start. you can also use your home computer as a PHP server for testing before you drop $ on a domain name, download wamp5:
http://www.wampserver.com/en/
installs php5, apache, mysql...
and for reference,
http://www.php.net has oodles of information.
Good luck
