Php Data structure algorithm (PHP description) simple selection and sorting simpleselectionsort_PHP tutorial

Php Data structure algorithm (PHP description) simply selects and sorts simpleselectionsort. Copy the code as follows :? Php *** simple selection and sorting simpleselectionsort ** principle: select each number in the array at a time, write down the current position, and assume that it starts from the current position. The code is as follows:

/**
* Simple selection and sorting simple selection sort
*
* Principle: select each number in the array at a time, write down the current position, and assume that it is the minimum number min = I in the number following the current position, scanning from the next number of this number until the last number, and recording the min position of the minimum number. If min is not equal to I after scanning, it is assumed that it is incorrect, the number of min and I positions is switched.
