math - PHP Round function - round up to 2 dp?

In PHP how would i round up the value 22.04496 so that it becomes 22.05? It seems that round(22.04496,2) = 22.04. Should it not be 22.05??

Thanks in advance

you can do it using ceil and multiplying and dividing by a power of 10.

echo ceil( 1.012345 * 1000)/1000;

1.013
