The installation is successful until "Syntax OK" appears in the terminal. This time, with the phpinfo() function, you can seePHP Version 7.1.0alpha2

2, solve the problem of MySQL link, because PHP7 abandoned the MySQL extension function (mysql_*), all link MySQL to use PDO, and PHP7 pdo_mysql.default_socket default path is/tmp/ Mysql.sock, and Mysql.sock path in/private/var/mysql/mysql.sock, so need to do a soft connect to TMP folder, execute under Terminal

?

12	cd /tmpsudo ln -s /private/var/mysql/mysql.sock mysql.sock

If you resolve the above error, the PHP link database will prompt you:SQLSTATE[HY000] [2002] No such file or directory

3, restart Apache and MySQL, so you can!
