PHP三元运算符不工作但不显示任何错误

问题描述：

<?php
    /*if(isset($_COOKIE["telcoProvider"])) {
        $telcoProvider = $_COOKIE["telcoProvider"];

    } else {
        $telcoProvider = "NOT FOUND";
    }*/

    $telcoProvider = isset($_COOKIE["telcoProvider"]) ? $_COOKIE["telcoProvider"] : "NOT FOUND".

    print "<p>Your telecommunication company is <b>$telcoProvider.</b></p>";
?>

I have checked the browser and the Cookie is there.

It works with the normal if-else, but not with the ternary operator. It does not proceed to the print, yet, it does not display any error either.

What am I missing?

 ＆lt;？php 
 / * if（isset（$ _ COOKIE [“telcoProvider”]））  {
 $ telcoProvider = $ _COOKIE [“telcoProvider”]; 
 
} else {
 $ telcoProvider =“NOT FOUND”; 
} * / 
 
 $ telcoProvider = isset（$ _ COOKIE [“telcoProvider”  “]）？  $ _COOKIE [“telcoProvider”]：“未找到”。
 
打印“＆lt; p＆gt;您的电信公司是＆lt; b＆gt; $ telcoProvider。＆lt; / b＆gt;＆lt; / p＆gt;”; 
？＆gt;  ; 
  code>  pre> 
 
 我已经检查了浏览器并且Cookie已经存在。 p> 
 
 
它适用于正常的if-else，但是 不是三元运算符。 它没有进入 print  code>，但它也没有显示任何错误。 p> 
 
 
我缺少什么？ p> 
  div  >

答

$telcoProvider = isset($_COOKIE["telcoProvider"]) ?
 $_COOKIE["telcoProvider"] : "NOT FOUND".
                                        ^

What's that dot (.) doing there instead of a ; ?

I wonder why Eclipse did not say anything?

Try this and you will get to an answer to that question :) Note the dot before print

$test= 1==1? "Oh nice no print :P " : "Oh" . print("Really?");
var_dump($test);
