为什么在函数中返回字符串时，PHP为什么要删除第一个单词之后的空格 [英] Why does PHP remove the space after the first word when returning a string in a function

问题描述

由于某种原因，在php函数中返回字符串时，第一个单词之后的空格将被删除.我不知道为什么.

For some reason, the space after the first word is removed when returning a string in a php function. I can't figure out why.

function something() {
   $string = "My sentence looks like this";
   return $string;
}

function something_else() {
   $output = something();
   echo $output;
}

输出"Mysentence看起来像这样"

Outputs "Mysentence looks like this"

如果我在第2行之后添加 echo $ string; ，它将正确打印 $ string .但是，第二个函数不会以这种方式输出它.

If I add echo $string; after line 2 it prints $string correctly. However, the second function does not output it that way.

此外，我可以通过将第2行更改为

Also, I am able to get it working by changing line 2 to

$string = "<strong>My sentence</strong looks like this";
