php - Preg_match symbols using? -


in code 

<div class="count">#3</div><div class="count">#4</div><div class="count">#5</div>

the numbers different every time how can see them , sum tested with

$b = explode('</div><div class="count">', $cnt); for($i=1;$i<sizeof($b);$i++)     preg_match("/([0-9]+)/", $b[$i], $m);

but see numbers not sum :(

you don't need regular expressions even:

echo array_sum(str_split(filter_var($string, filter_sanitize_number_int)));

outputs

12

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
