今天是二阶段的第一天学习!

作业:PHP对字符串的处理规则

代码

$title1 = '单引号原样输出{$SMS}!';

$title2 = "双引号解析内容包含变量{$SMS}";

echo "用转义字符:反斜线,将原字符进行转义,使其失去原有的作用"

回车\r,换行符\n,制表符\t,美元符\$

heredoc结构相当于双引号

$heredoc = <<< HEREDOC

这是第一次的作业比较匆忙{$bianliang}

HEREDOC;

nl2br相当于单引号

$nowdoc = <<< 'NOWDOC'

www.php.io<h1>$bianliang<h1>

NOWDOC;
