| 3 | !!! Introduction | ||
| 4 | [PHP] was created for serverside scripting of [WebPage]s. From humble beginnings, it has become one of the most powerful languages for web application development. | ||
| 5 | |||
| 5 | CraigBox | 6 | !Advantages of PHP (over other languages): |
| 7 | |||
| 8 | * Rapid Development: PHP is simple, fast and effective. | ||
| 1 | AristotlePagaltzis | 9 | * PHP can be as simple or as complex as you like. |
| 10 | * One of the best Manuals of ANY language I've used (or even tried to learn) http://www.php.net/manual/en/ | ||
| 11 | * C/++ based, if you can program in C/++ or even PERL or JAVA, you should be able to take to it like a fish to water. | ||
| 12 | * Built in mySQL API (built in SQL DB in PHP5beta) | ||
| 13 | * so many many more .... | ||
| 14 | |||
| 5 | CraigBox | 15 | !Cons of PHP: |
| 16 | |||
| 17 | Yes, there are some downsides to PHP | ||
| 18 | |||
| 19 | * Not as modular (OOP) as [JSP] (JavaServerPages) / Servlets. | ||
| 1 | AristotlePagaltzis | 20 | * Easy to code without thinking. |
| 21 | |||
| 22 | !!Getting Help! | ||
| 5 | CraigBox | 23 | |
| 24 | Always check the [online manual|http://www.php.net/manual/en/]. It has a wealth of user submited notes and is categorised by [Function]. | ||
| 25 | |||
| 26 | You can generally find the author in either [#wlug] or #phphelp on the UnderNet [IRC] network. There is also #php on the same network but #phphelp is so much better! (shameless plug) ;) | ||

| 28 | If there is enough interest I will continue to expand this section as I have time / people bug me. | ||

| 30 | !!Installation | ||
| 5 | CraigBox | 31 | |
| 1 | AristotlePagaltzis | 32 | See the docs below (outdated) or the Manual ... This is one program where it pays to read the manual when things down work. |
| 33 | Else come and me ask nicely. | ||
| 34 | |||
| 35 | !!Tips | ||
| 36 | |||
| 37 | __DONT__ put $_POST, $_GET or $_REQUEST varible straght into an SQL statment! Rather put the varible through the [mysql_escape_string()|http://www.php.net/manual/en/function.mysql-escape-string.php] function. | ||
| 38 | Ignoring this leaves you database exposed to attacks from [ScriptKiddie]s. %%% ie. | ||
| 39 | $myVarFromForm = mysql_escape_string($_REQUEST[['myVarFromForm']); | ||
| 40 | $SQL = "SELECT * FROM mytable WHERE mycol = '$myVarFromForm'"; | ||
| 41 | |||
| 42 | "" != '' - you can insert varibles directly into double quoted strings! Arrays (and objects) can also be inserted this way by puting the varible in a set of {} squiglyBrakets ! %%% ie. | ||
| 43 | $var = 'Hello ' . $name . ', ' . $myArray[[3] . ' is the 3rd array element'; | ||
| 44 | can be writen as | ||
| 45 | $var = "Hello $name, {$myArray[[3]} is the 3rd array element"; | ||
| 46 | |||
| 47 | I would tend to use {$name} for clarity. | ||
