php: php simple dom parser question

Question

i'm using the php simple dom parser and found a little issue:

when the selector returns only one element, i also need to run a foreach loop for it. is there a simpler way to do it?

thanks

like in jQuery - when u get only one element you can directly access it by default. — Fuxi

You need to post your use case with code if we are to be any help to you — JohnP

all jQuery functions work on a multiset, meaning they don't care if it's one element or every single dom element. Give us a test case of what it is you are trying to achieve. — Khez

very simple: <div class=widget><input type=text value=bla></div> my code is: $txt = $ctl->find("input"); it's only one element but i can't access it like in jQuery with: echo $txt->value .. so i need to run a foreach loop everytime? — Fuxi

The manual says find() has a second parameter for exactly that:

mixed find ( string $selector [, int $index] )

Find elements by the CSS selector. Returns the Nth element object if index is set, otherwise return an array of object.

So in your case,

$txt = $ctl->find("input", 0);

should do the job.
