min Find lowest value numbermin numberarg1 numberarg2 ... numbermin arraynumbers min returns the numerically lowest of the parameter values. In the first variant, you need at least two parameters and min returns the lowest of these values. You can compare an unlimited number of values. If one of the variables is undefined, min will fail. In the second variant, min returns the lowest value in numbers. If one or more of the values is a float, all the values will be treated as floats, and a float is returned. If none of the values is a float, all of them will be treated as integers, and an integer is returned. Upon failure, min returns NULL and an error of level E_WARNING is generated. ]]> See also max.
