数组取值

Array<br />(<br />    [iso.3.6.1.4.1.2021.4.1.0] => INTEGER: 0<br />    [iso.3.6.1.4.1.2021.4.2.0] => STRING: "swap"<br />    [iso.3.6.1.4.1.2021.4.3.0] => INTEGER: 16777208<br />    [iso.3.6.1.4.1.2021.4.4.0] => INTEGER: 16777208<br />    [iso.3.6.1.4.1.2021.4.5.0] => INTEGER: 16324040<br />    [iso.3.6.1.4.1.2021.4.6.0] => INTEGER: 4484096<br /> <br />    [iso.3.6.1.4.1.2021.9.1.6.1] => INTEGER: 1032088<br />    [iso.3.6.1.4.1.2021.9.1.6.2] => INTEGER: 458942624<br />    [iso.3.6.1.4.1.2021.9.1.6.3] => INTEGER: 8162020<br />    [iso.3.6.1.4.1.2021.9.1.6.4] => INTEGER: 99150<br />    [iso.3.6.1.4.1.2021.9.1.6.5] => INTEGER: 3096336<br />    [iso.3.6.1.4.1.2021.9.1.6.6] => INTEGER: 1032088<br />  <br />)

怎么取键值是iso.3.6.1.4.1.2021.9.1.6.* 的值 就是把前面 键值是iso.3.6.1.4.1.2021.9.1.6的所有值 加起来

$ar = 你的数组<br />$res = array();<br />foreach($ar as $k=>$v){<br />    if(strpos($k, 'iso.3.6.1.4.1.2021.9.1.6') !== false){<br />	     $t  = explode(': ', $v);<br />	    $res[] = $t[1];<br />	}<br />}<br />echo array_sum($res);
