rating system

mike08

i have found this code for building a rating system without the use of mysql

could someone explain to me what 'ficdest means please as a few words are in a different language. cheers.


$ficdest=explode(".",basename($PHP_SELF)); 
$ficdest=$ficdest[0].".dat"; 

if(file_exists($ficdest)) { 
     $compteur=fopen($ficdest, "r"); 
     $old_stats=file($ficdest); 
     $stats=explode("|", $old_stats[0]); 
     fclose($compteur); 
     $new_count=$stats[0]; 
     if ($stats[3] != $REMOTE_ADDR) { 
         $new_count +=1; 
     } 
     $ip_hit=$REMOTE_ADDR; 
     $compteur=fopen($ficdest, "w"); 
     fputs($compteur, "$new_count|$stats[1]|$stats[2]|$ip_hit|$stats[4]"); 
     fclose($compteur); 

[code=php]

You dont really need to know what it means.

It basically holds a filename.

School assignment?

Do you understand all these functions?

[man]extract/man
[man]explode/man
[man]asename/man
[man]file_exists/man
[man]fopen/man
[man]file/man
[man]fclose/man
[man]fputs/man

btw, I notice:
get(REMOTE_ADDR);
I believe get() would be user defined.
Or it would be a typo for [man]getenv/man

mike08

yes apart from the 'expload' one?

ucbones

wow, I don't have a clue what asename() does, glad that Mike does 😉,

I'm guessing she meant [man]basename[/man]

😉

explode takes a string and splits it into an array, using a delimeter

so if i have a string

$string = "1st array entry.Second array entry.THIRD array entry";

and i use explode to split $string by period (.)

$parts = explode(".", $string);

then it's the same as saying

$parts[0] = "1st array entry";
$parts[0] = "Second array entry";
$parts[0] = "THIRD array entry";

[man]basename[/man] takes a valid url and returns the filename component - so in this context, it's getting the filename of the current script.

hope that helps

slight correction:

$parts[0] = "1st array entry"; 
$parts[1] = "Second array entry"; 
$parts[2] = "THIRD array entry";

sorry... late night + copy & paste = stupid typo's

ucbones

no worries!
