How to obtain constellation and Zodiac signs using ID card numbers in PHP

Copy codeThe Code is as follows:
<? Php
// PHP automatically obtains the corresponding constellation function based on the ID card number
Function get_xingzuo ($ cid) {// automatically returns the corresponding Constellation Based on the ID card number
If (! IsIdCard ($ cid) return '';
$ Bir = substr ($ cid, 10, 4 );
$ Month = (int) substr ($ bir, 0, 2 );
$ Day = (int) substr ($ bir, 2 );
$ StrValue = '';
If ($ month = 1 & $ day> = 20) | ($ month = 2 & $ day <= 18 )){
$ StrValue = "Aquarius ";
} Else if ($ month = 2 & $ day> = 19) | ($ month = 3 & $ day <= 20 )){
$ StrValue = "Pisces ";
} Else if ($ month = 3 & $ day> 20) | ($ month = 4 & $ day <= 19 )){
