php 使用phpize 安装扩展readline , 安装后可以进入命令行交互模式：
#php -a Interactive shell php > $name="jackxiang"; php > $address="home"; php > echo $namegoto$address; PHP Parse error:  syntax error, unexpected '$address' (T_VARIABLE), expecting ',' or ';' in php shell code on line 1 php > echo "${name}goto${address}"; jackxianggotohome php > echo "{$name}goto{$address}";   jackxianggotohome

Shell也一样：
#set names="jackxiang" #set address="home" #echo ${names}goto${address} jackxianggotohome #echo {$names}goto{$address}   jackxianggotohome ]]> https://jackxiang.com/post//#blogcomment <user@domain.com> Thu, 01 Jan 1970 00:00:00 +0000 https://jackxiang.com/post//#blogcomment
