将php调用作为href值返回

Question

I'm quite new to using php so im not sure if this is possible or not;

What I'm looking to do is call a php function from within a href tag, and use the returned value as the tag..

for example, i have the following code:

HTML

<a href= 'tele.php'> <img src="images/image1" alt="Preview1" /> </a>

then:

PHP

<?php
return header("Location: tel:[phone]");    
exit;       
?>

I want the href tag to be what the php code returns: "Location: tel:[phone]". Is it possible to do this? or am I going about this the wrong way?

Answer 1

header() returns void, so that PHP code doesn't return anything.

But you probably want something like this:

<?php
   function foo() {
       return "tel:[phone]"
   }
?>

<a href= '<?php echo foo(); ?>'> <img src="images/image1" alt="Preview1" /> </a>
