[SOLVED] convert decimal to hex

[otuatail]

hi. Can anyone tell me if it is possible to convert a number to its hex equivelent. I want to generate a random number 0 - 65535 and to convert this to 0000 to ffff

 

Any ideas on this please.

 

Desmond.

dechex() should do the trick

for more control over the output (width, leading zeros, case) you can use sprintf() or printf()

 

printf ('%04X', rand(1,65535));

Thanks guys that worked. Remeber printf from old days. I wanted it in a string and

remembered sprintf.

 

Works a treat

 

Thanks.
