what is the meaning for <?php=$url?>

[william6789]

Hi,
There is one code syntax I could not run and I do not understand how it works yet? I copy it from one booke named "PHP and MySQL Web Development" edited by Luke Welling and Laura Thomson, Page 553. Is it a typo?

Function do_html_URL($url, $name)
{
// outpur url as a link
?>
<a href=&quot;<?=$url?>&quot;><?=$name?></a><br>
<?

}

This function could not give me a link , and I could not understand the syntax of <?=$url>.

Can someboyd give some ideas about it?

Thanks

William

Function do_html_URL($url, $name)
{
//this closes any open php so the quotes wont mess it up
?>

//this opens php <? then inserts a string $url then closes the php does more html and then opens the string again.
<a href=&quot;<?=$url?>&quot;><?=$name?></a><br>
//this opens up the php again
<?

}



probably would be clearer if they did it like this..

<a href=&quot; <? =$url ?> &quot;><? =$name ?></a><br>



oh i think i see what you mean... hmm no idea why the = is there.. wierd.. lemme look at my version right fast..

nope dont see it... i would say its a typo if that is whats in the book..drop the ='s and it should work fine as long as its fead the right info

in the begining man created code.
in the end code will create man.
clones are coming only matter of time.
examples?

I would do it like this:

function do_html_URL($url, $name) {
  // output url as a link
  ?>
  <a href=&quot;<? echo $url; ?>&quot;><? echo $name; ?></a><br>
  <?
}

This should work fine...

u can't put <?=, <? & ?> must be alone.. and u have to use either echo or print to output the content of a variable, like:

<a href=&quot;<? echo $url; ?>&quot;>
or
<a href=&quot;<? print $url; ?>&quot;>
but never
<a href=&quot;<? $url; ?>&quot;>

another problem u have in your function, when u close with ?>, put <a> and then re.open it <?, the <a> doesn't even belong to the function because it's out of <? ?>.

so, u should use:

<?
function do_html_URL($url, $name)
{
echo &quot;<a href=\&quot;$url\&quot;>$name</a><br>&quot;;
}
?>

Actually, jamesp0tter you can do all of that, it's just a collection of shortcuts... the possible problem is actually taken care of in the thread title... some installations of php won't recognize

<?

as an opening tag, you'll need <?php

However, I do agree with, it's a silly way to do it... I would've suggested

function doHtmlUrl($url, $name) 
{
  echo '<a href=&quot;'.$url.'&quot;>'.$name.'</a><br />';
}

but at that stage it's just whatever you're style is.

Actually, the &quot;<?= $foo ?>&quot; construct is a shorthand for <?php print $foo; ?>&quot;.
