hi every one a problem in project i have admission page in that i need auto generating number,every time i refresh the page i need to get autogenerating number can any one help me

If you're on about generating a random number then you probably want rand()



     print rand() . "<br>"; 
     //generates and prints a random number

     print rand(10, 30); 
     //generates and prints a random number between 10 and 30 (10 and 30 ARE included)

     print rand(1, 1000000); 
     //generates and prints a random number between on and one million


Check out this link:

$numchars = rand(4,15); 
            $chars = explode(',','a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,0,1,2,3,4,5,6,7,8,9'); 
            for($i=0; $i<$numchars;$i++)  


it will generate alphnumeric random number every time when page is refreshed.
