php：php简单的dom解析器问题

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

Answer 1

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.
