Full Version: Knowledge of PHP
Oh well, all this Object Oriented stuff dosent click for me, but my scripts are killer fast!
I know how to make sessions, mysql interface, regular expressions,etc, and 1/2 OOP. I have yet to use it much, but I can use it, but not all advanced stuff. And I can't do fancy schamey stuff. 
I know that echo prints stuff to the HTML and i know while loops
I know how to use arrays, advanced conditionals
But what do you mean by "advanced conditionals?"
I know how to make mysql interface
I can do OOp
OOP is easy
Probably because the first programming language I learned was completely OOP

I know just about enough.
I know what echo does, and what print does. I know about variables and using php with mysql (add, edit, and delete rows, create table, call up mysql info from mysql with php).
I don't know how to use loops (those confuse me).
And sessions, haven't gotten around to learning that yet.

While loops are pretty easy.
while (conditional) {
body;
}
What that does is that when it gets to there, it checks to see if conditional is true. If it is, it runs the body, then repeats from the start, checking the conditional again. If the conditional is false, then the loop ends and it goes on to the next line.
-----Edit-----
And I might as well get to for loops too.
for (initialization; conditional; increment) {
body;
}
This is pretty much the same as
initialization;
while (conditional) {
body;
increment;
}
Initialization usually sets up a variable. Then the conditional will check the variable's value. Then the increment will change the variable's value.
while (conditional) {
body;
}

added a PHP tag. You can see it right after the code button
Took out the return statement, since it contained the php tag, and messed things up.
PHP
<?php
function unparse_php_tag($txt="")
{
global $ibforums;
$txt = str_replace("<!--SDS-->$<!--EDS-->", "$", $txt);
$txt = str_replace("<code>" , "" , $txt);
$txt = str_replace("</code>", "" , $txt);
$txt = str_replace("</font>", "" , $txt);
$txt = str_replace("</span>", "" , $txt);
$txt = preg_replace("#\<font(.+?)>#", "", $txt);
$txt = preg_replace("#\<span(.+?)>#", "", $txt);
$txt = preg_replace("#^<span(.+?)><br />(.+?)#", "\\2", $txt);
$txt = preg_replace("#(.+?)(?:<br />){1,}$#", "\\1", $txt);
$txt = str_replace("<br />" , "\n", $txt);
}
?>

$txt = preg_replace("#(.+?)(?:<br />){1,}$#", "\\1", $txt);
$txt = str_replace("<br />" , "\n", $txt);

Thanks, been wondering about those for a bit.
The only stuff I use is really just echo, print, variables, and anything that has to do with mysql control in php.

I know the OOP stuff. Although I'm a little worse with it on PHP5 then on PHP4.

What's that "alipanel" you are coding?
Woah, just went to your website...changed for the first time in 1000 years
By advanced conditionals I mean switch statements and, um well... If, elseif, else i guess? I dont really know
foreach is a useful loop...

Those are advanced...?
What about the ? : thing?
I think Java has a special foreach thing too. But it only works with Iterators. And it's still called a for loop. Just has a different format.
I made a temperature converter...granted I was using a guidebook...but I have little use for PHP.

That could more easily be done with Javascript.
Or TI Basic

lmao, with World of Warcraft and IRC and all the other junk I do, I don't have much time for my site. I'm tempted just to use phpnuke instead of coding my own site, but what holds me back is the memory of how weird the phpnuke system is. I'll get to coding it again in the summer. I'll be going to a tech came for about a week (maybe more), so that will cut a bit of time out of my site.Woah, just went to your website...changed for the first time in 1000 years
aliPanel will be the cms I'll use for my site. I first intended it to be something I'd sell to little 7th graders (all of them are midgets! D=) who want to make a website. They'd have their website and I'd have money. Now I decided just to make it for my site only. I'd make money by teaching students web design stuff and fixing websites for them and related stuff. I charge S$10-S$20 for 1 lunch break of tutorial, and $10 for a web site fixing.
Yeah, making the upgrader and installer and the User-Friendly parts are the hardest (from my experience in PHPKImageHost)
This is an example from the mailscript admin page
http://www.dubemail.com/mail/admin.php
Note the while loop to go trhough each row from the SELECT query. Thats one of the mysteries of php, using a while loop for that.
Also, a foreaach wouldnt work in for each cell in the row, becuse what if a cell was empty? there would be a misalignment.

Wouldn't a for loop work better for that?
PHP
for ($i = $num_rows - 1; $i != 0; $i--)
{
$blah-->doSomething();
}
{
$blah-->doSomething();
}
The reason why I made it start out high and then decrease is because comparing to 0 is very fast.
I suppose a for loop is faster, but how many microseconds differnece does it make when the server is comparing 100 to zero as apposed to 0 to 0?
Even better:
mysql_fetch_array returns false if there are no more db records to get.
PHP
<?php
//assume mysql is already connected, database is already selected, etc...
$queryresult = mysql_query('SELECT * FROM EmailSent ORDER BY 'id' ASC')
while($row = mysql_fetch_array($queryresult))
{
echo "Name: $row['name'] IP: $row['ip']"; //etc etc.
}
?>
