[SOLVED] rand() and AJAX php 4 prob 5 ok

[nadeemshafi9]

hello guys

 

here is the code that i call with an XMLHttpRequest object in javascript every 3 seconds

 

rando();

 

function rando(){

$d = rand(1, 10);

 

print $d;

 

$d = rand(1, 10);

return;

}

 

IN PHP 5

everything works fine the number is different every call

 

IN PHP 4

the number stays the same every call

 

i tried destroy session delete unlink and all that no luck

your function doesn't make sense and it might be erroring without your knolwedge

 

this is what it does ask yourself if this is what you need

 

Makes a random number 1-10

Echoes it

and then makes another one

and the function is over

the second making has no purpose because the local function variables is unset on the end of the function so make your page say this insated

<?php
echo rand(1,10);
?>

that is it no need to do all the extra cause its pointless

this function is just somthing i done in one second so u guys cant see my work, the thing is in php4 when ajax calls the script it generates a random number reguardless of the script iv shown u , the random number is added to page the ajax is in, this works fine in php 5 but in php 4 for some reason it dosent run the script properly and get the random number new one until i close the browser and open it again.

did u try what I gave you that function you built was broken and if it errors there is your problem

[nadeemshafi9]

i tried what u gave me it works fine in php 5 on iis, but in php4 on apache on the server i use it dosent seem to return a different number when called using XMLHttpRequest object from another page,

 

the ajax calls getrand.php whcih outputs teh rand and then the javascript inserts it into teh current page

i have a 3 second timout on the javascript function which calls the php script over and over

 

u see this is what shoudl happen like in php 5 on my machine

 

1 then the ajax happens then 1233213, then teh ajax happens then 2345535 or somthing

 

but on my live server this is whats happening

 

1 then wait 1 then i wait 1 etc

 

if i close teh browser then it gens a new number this is what happens

 

 

3444 and then 3444  and then 3444

 

its like its not even runing the script more than once

could this be ebcause its cachig teh output of teh php script ?

 

 

[cooldude832]

if u just run that page does it return correctly? if so then its not a php problem its your ajax
