我必须找到在每个组SP1的最接近的值SP10的阵列[0] - >使用STATIC_PRESSURE = 0.34， 阿雷[2] - > 1个 阵列[3] - > 23.等等.. 请帮我在这里im结构。

Answer 1

这将搜索名称为“SPx”的每个数组键中的最高值，其中x表示数字，也许您可​​以在此基础上构建，因为我不明白您的意思“STATIC_PRESSURE = 0.34，aray [2] - > 1阵列[3] - > 23.等等。“

$count = 0; 
$max = array(); 
foreach ($array as $values) { 
     $max[$count] = 0; 
    foreach ($values as $key => $val) { 
     if(preg_match('/SP\d/', $key)===1){ 
      if($val>$max[$count]){ 
       $max[$count] = $val; 
      } 
     } 
    } 
    $count++;  
} 
var_dump($max);
