单引号或双引号的PHP Echo语法错误？

Question

这是一个非常简单的回声,但我无法解决它？

echo '"What is your name?'";

Answer 1

单引号不匹配,请使用:

echo '"What is your name?"';

你的第一个封闭字符是单引号,但结尾一个是引用问题的双引号

Answer 2

不正确:

echo '"What is your name?'";
                          ^ Unexpected character

正确:

echo '"What is your name?';

正确:

echo "What is your name?";

正确:

echo 'What is your name?';

正确:

echo '"What is your name?"';

正确:

echo "'What is your name?'";

Answer 3

您的引号嵌套不正确.

Answer 4

echo "What is your name?";

这简直就是最好的。没有混乱没有问题..:)
