Hey I have a problem with Simple DOM parser which is driving me nuts.
This works OK:
foreach($html->find('input[name=sex]') as $e)
echo $e->value;
Even if its only 1 result.
However this doesn't work:
echo $html->find('input[name=sex]')->value;
I don't want really use foreach because I expect only 1 result. So someone could help me with second block of code?
Cheers
According to the docs, the second parameter is the index you wish to find. Set that to 0 to return the first (0th) element rather than an array of objects:
Find elements by the CSS selector. Returns the Nth element object if index is set, otherwise return an array of object.
$html->find('input[name=sex]', 0)->value;
$html->find('input[name=sex]')[0]->value;
It seems find returns an array so using index would help you.
Use the code above.
If you can use for-each on something, it is an array/collection, even if there is one element. You are asking to echo an entire array, for which which may need print_r. As another poster suggested, use a subscript.
->find()returns a results object, which can be boiled to an array of matching elements. You're doing->valueon the whole array, instead of one of the actual elements.
