Php：从函数返回一个字符串[关闭]

The simple program is not returning the string,Please help.

<?php 
function returnStr() {
return "fooBar";
}
$str=returnStr();
echo $str;
}
?> 

There's a fatal error tokenizing the code due the trailing/unmatched '}' remove that and the code will work. Then spend some time thinking about why you didn't know this already

It's a parse error:

$str=returnStr();
echo $str;
}                   // WHAT IS THIS BRACKET DOING HERE?

There's an error in your code. The last } is useless.
