[SOLVED] Random letter?

[ERuiz]

Hello guys and gals,

 

Look at the following code:

 

if ($carrier == "Chautauqua Airlines") {
$reg_number = rand (100, 999);
$reg_number = "N".$reg_number."SK";
}

 

As you can see, if $carrier equals Chautauqua Airlines, then it will make a random number from 100-999 and build the following result: N###SK

 

What I want to know is how can I also make this code so that instead of always using SK, it would randomly select between using SK or JQ or RP?

 

Thanks for any help, as always.

 

Regards,

 

ERuiz

Well it depends what you want, do you want a random string with alphanum, with a certain ammt of digits, or do you just want to choose from SK,JQ,RP

<?php

$random_letter_ucase = chr(rand(ord("A"), ord("Z"))); 


if ($carrier == "Chautauqua Airlines") {
$reg_number = rand (100, 999);
$reg_number =  ($random_letter_ucase+1),$reg_number,($random_letter_ucase+1);

///should output something like  FG###SD
}?>

do you just want to choose from SK,JQ,RP

 

Exactly, I simply want it to randomly choose between these 3 options: SK, JQ, RP

[darkfreaks]

how about

<?php
$array= array("SK","JQ","RP");

$randarray= shuffle($array);


echo $randarray; echo $regnumber; echo $randarray; ?>

[ERuiz]

how about

<?php
$array= array("SK","JQ","RP");

$randarray= shuffle($array);


echo $randarray; sprintf($regnumber); echo $randarray; ?>

 

The result of $randarray is coming back as 1

[darkfreaks]

link me? it should be outputting something like

 

<?php

/// SK###JQ ?>

 

 

<?php
$array= array("SK","JQ","RP");

$randarray= shuffle($array);


echo $randarray; echo $regnumber; echo $randarray; ?>

<?php
$array= array("SK","JQ","RP");
$randarray= array_rand($array);
$randarray2= array_rand($array);
echo $array[$randarray]; sprintf($regnumber); echo $array[$randarray2]; ?>

 

 

[darkfreaks]

oh my bad thanks tech

[MadTechie]

darkfreaks remember shuffle will shuffle an array BUT whats does it return!!!

 

shuffle($array);

not

$randarray=shuffle($array); as it returns a boolean

 

EDIT: oh if you must have different random items then shuffle works well

ie

<?php
$array= array("SK","JQ","RP");
shuffle($array);
echo $array[0]; echo $regnumber; echo $array[1]; ?>

which i think darkfreaks  was aiming for

[darkfreaks]

LOL i just scrolled down on the function on php.net i should read more thouroughly

[ERuiz]

<?php
$array= array("SK","JQ","RP");
$randarray= array_rand($array);
$randarray2= array_rand($array);
echo $array[$randarray]; sprintf($regnumber); echo $array[$randarray2]; ?>

 

 

 

Thanks! That did the trick! Also MANY thanks to darkfreaks, who also helped out. Thanks to both you guys.

your welcome sorry i couldnt be of more help ruiz but im just learning how to randomize arrays and didnt know what function to quite use as there is many functions in PHP that will randomize an array

 

also hit topic solved

[MadTechie]

in darkfreaks defence i have seen LOTS of people attempt shuffle like that..

 

also please be aware.. that the code you use will allow results like SK###SK and JQ###JQ where as the following code will not..

 

EDIT: oh if you must have different random items then shuffle works well

ie

<?php
$array= array("SK","JQ","RP");
shuffle($array);
echo $array[0]; echo $regnumber; echo $array[1]; ?>

which i think darkfreaks  was aiming for

[darkfreaks]

oh sorry i forgot to number array i guess its like using any variable to row *slaps head*

 

that and i shouldnt put a variable before shuffle haha
