Call a function in class and then use if statement.

[bbmak]

I want to use a class function to validate url. Here is the code.
I want to have something like

if (!validateURL($URL) == FALSE) {
echo "Please enter a valid URL";
}

How do I have the if statement for a function in a class?

$validate = new validate();
$validate->validateURL($URL);

<?php
class validate {


//Validating URL
function validateURL($URL) {
    $v = "/^(http|https|ftp):\/\/([A-Z0-9][A-Z0-9_-]*(?:\.[A-Z0-9][A-Z0-9_-]*)+):?(\d+)?\/?/i";
    return (bool)preg_match($v, $URL);
}
//Validating URL
}

?>

Declare the method as [man]static[/man] and use

Classname::methodname()

Any reference link?

Do you also have a link to talk about the usage of private, public, static, and etc in a function? I am kind of confuse on those as well. or what do you guys call them? I can google it myself.

Note that you don't necessarily have to define it as static, but if you don't, then you'll need to instantiate an object, first.

$validate = new validate();
if($validate->validateURL($URL) == false) {
  echo "Please enter a valid URL";
}

However, if the intent is for the Validate class to simply provide stand-alone validation functions, then the static approach is probably a good idea.

Generally, I assume the most restrictive access level that makes sense, then loosen it later if I find out it needs to be less restrictive.

As for a link to the description of visibility levels (private, public, and so on), there happens to be one on the page I linked to.

...if no visibility declaration is used, then the property or method will be treated as if it was declared as public.

More details (actually, everything about object orientation as it is done in PHP) can be reached by the links on the left of that page.

Actually can you show me how static approach do in the same if statement situation? I am new to oop.

[Weedpacket]

if(validate::validateURL($URL) == false)
{
    echo "Please enter a valid URL";
}

[bbmak]

So they are pretty similar.
what about in the class? just put in a

public static

????

public static function validateURL($URL)

[Weedpacket]

Yes, as in example #2 on the [man]static[/man] manual page.

Isn't this situation an ideal candidate for the filter_var() function with the FILTER_VALIDATE_URL flag?
