从这些条目中，我想从PHP中的“尝试ArayaFug”开始考虑数组。该函数检查数组值是否以

[1901] => <444209603509>MY FINANCE 
[1931] => <444990698490>good FINANCE 

 foreach($arr as $key=>$val){
            if(substr($val,0,1)=='<')
                $new_arr[$key]=$val;
        }
        print_r($new_arr);

function myFilter($val){
            $val = trim($val);
            return ($val[0]==='<');
}


array_filter($array,'myFilter');
