[SOLVED] What exactly does this mean?

[networkthis]

$name    = isset($_POST['name']) ? $_POST['name'] : "";

 

I have seen this in some sample forms online and I am just trying to make sure that I am understanding it properly.  I am trying to learn the language to build smarter php forms.  Any help would be great. 

 

 

isset -- checks to see if the variable has a value........Therefore, isset($_POST['name']) is checking to see that ($_POST['name']) has a value

 

? - What does the ? mean in this statement

 

$_POST['name'] :""  --- What does the :"" mean in this statement

 

Thank you in advance for your help

erm, ok i just heard this a few minutes ago,

? that sets what happens if it is true or not

for example this

 

$variable_name = (clause) ? true:false;

[networkthis]

Thanks for the quick response so

$name    = isset($_POST['name']) ? $_POST['name'] : "";

 

means:

if $name has a value then set the value to what was inputed in $_POST['name']

if $name has no value then set it equal to nothing (")

 

You rock...thank you!!!

<?php
$string = isset($isset) ? "Yes" : "No";
echo $string;
?>

Outputs No

 

<?php
$isset = 1;
$string = isset($isset) ? "Yes" : "No";
echo $string;
?>

Outputs Yes

If you ever need to look it up, it's called the ternary operator.
