将 php 数组内爆为格式化文本

Question

我有这个数组：

array(122) { 
    ["1AB168820010"]=> array(3) { 
       ["MACHINE_NAME"]=> "L1XP2A"
       ["FEEDER_SLOT"]=> "114"
       ["REJECT_RATE"]=> float(0.0394) 
       ["DEFECT_QTY"]=> int(2) 
       ["SOLDER BALL"]=> int(2) 
    }  
    ["1AB037870031"]=> array(5) { 
       ["MACHINE_NAME"]=> "L2CP7A"
       ["FEEDER_SLOT"]=> "155"
       ["REJECT_RATE"]=> float(2.3022) 
       ["DEFECT_QTY"]=> int(39) 
       ["COMPONENT TOMBSTONED"]=> int(31) 
       ["SOLDER BALL"]=> int(2) 
       ["COMPONENT BILLBOARD"]=> int(6)
    } 
    ["1AB144890021"]=> array(7) { 
       ["MACHINE_NAME"]=> "L21P3A"
       ["FEEDER_SLOT"]=> "214"
       ["REJECT_RATE"]=> float(0.0225) 
       ["DEFECT_QTY"]=> int(8) 
       ["SOLDER INSUFFICIENT "]=> int(2) 
       ["SOLDER BAD"]=> int(2) 
       ["SOLDER BALL"]=> int(2) 
       ["COMPONENT MISSING"]=> int(1) 
       ["COMPONENT BILLBOARD"]=> int(1) 
    } 
    ["1AB144890033"]=> array(7) {
       ["MACHINE_NAME"]=> "L1CP7A"
       ["FEEDER_SLOT"]=> "234" 
       ["REJECT_RATE"]=> float(0.0142) 
       ["DEFECT_QTY"]=> int(7) 
       ["SOLDER INSUFFICIENT "]=> int(1) 
       ["SOLDER BAD"]=> int(1) 
       ["COMPONENT MISSING"]=> int(3) 
       ["COMPONENT SKEW"]=> int(1) 
       ["COMPONENT TOMBSTONED"]=> int(1) 
    }
    #...more
}

我需要循环遍历该数组并从数组输出创建一个看起来像这样的字符串，但不知道最好的方法...请帮助

 1AB168820010 ( 0.0394% ) #<-this is the 'REJECT_RATE'
  -Machine: L1XP2A
  -Feeder: 114
     SOLDER BALL ( 100% ) #<-'SOLDER BALL' value (2) divided by 'DEFECT_QTY' (2) * 100
 ------------------------
 1AB037870031 ( 2.3022% ) 
  -Machine: L2CP7A
  -Feeder: 155
     COMPONENT TOMBSTONED ( 79.48% ) #<- ( 31 / 39 ) * 100
     COMPONENT BILLBOARD ( 15.38% )  #<- ( 6 / 39 ) * 100
     SOLDER BALL ( 5.12% ) #<- ( 2 / 39 ) * 100
 ------------------------
 1AB144890021 ( 0.0225% )
  -Machine: L2IP3A
  -Feeder: 214
     SOLDER INSUFFICIENT ( 25% )
     SOLDER BAD ( 25% )
     SOLDER BALL ( 25% )
     COMPONENT MISSING ( 12.5% )
     COMPONENT BILLBOARD ( 12.5% )
 ------------------------
 1AB144890033 ( 0.0142% )
  -Machine: L1CP7A
  -Feeder: 234
     SOLDER INSUFFICIENT ( 14.3% )
     SOLDER BAD ( 14.3% )
     COMPONENT MISSING ( 42.8% )
     COMPONENT SKEWED ( 14.3% )
     COMPONENT TOMBSTONED ( 14.3% )

我的主要问题是我不确定如何处理我不知道每个零件号的缺陷数量（即组件缺失、组件倾斜、焊接不良）、有多少缺陷（以及它有哪些缺陷）会有所不同，因此我不能只硬编码“组件缺失：” [一些计算]'进入我的foreach循环......

Answer 1

有两种方法：简单和“正确”:)

简单方法：

foreach ($array as $machine_key=>$machine){
    $solder_ball = $machine['SOLDER_BALL']/ $machine['DEFECT_QTY']*100;
    echo "$machine_key ({$machine['REJECT_RATE']})";
    echo " -Machine {$machine['MACHINE_NAME']};
    echo " -Feeder {$machine['FEEDER_SLOT']}";
    echo "  SOLDER INSUFFICIENT ( $solder_ball%)";
    //...and so on...//
}

“正确”方法

有类 Machine：

class Machine{
    $protected $name, $feeder, $solder_insufficient; //..all youneed to output here..//
    function__constructor(Array $params){
        $this->name = $params['MACHINE_NAME'];
        $this->solder_insufficient = $machine['SOLDER_BALL']/ $machine['DEFECT_QTY']*100;
        //..all other params here...//
    }

    function output(){
        echo "{$this->key} ({$this->reject_rate)";
        echo " -Machine {$this->key}";
        echo " -Feeder {$this->feeder}";
        echo "  SOLDER INSUFFICIENT ( {$this->solder_insufficient}%)";
        //....and so on ..//
    }
}

使用“正确”方法的好处是您可以多次重用您的类，并调整输出所有需要它的地方只需修改单个位置的代码即可。

Answer 2

（您可以选择按键对数组进行排序：ksort($array);。）

接下来，迭代每个元素并构建字符串：

$output = '';
foreach ($array as $key => $data) {
  $output .= $key . ' ( ' . number_format($data['REJECT_RATE'], 3) . '% )' . "\n";
  $output .= ' -Machine: ' . $data['MACHINE_NAME'] . "\n";
  $output .= ' -Feeder: ' . $data['FEEDER_SLOT'] . "\n";
  $output .= '  SOLDER BALL ( ' . number_format(2 / $data['DEFECT_QTY'] * 100, 0) . '% )'. "\n";

  // Add more calculation here…

  $output .= "------------------------\n";
}

最后，输出字符串：回显$输出；。

Answer 3

这可行

foreach($arr as $id => $item) {
  printf('%s ( %s )
  -Machine: %s
  -Feeder: %s
',
  $id,
  $item['REJECT_RATE'],
  $item['MACHINE_NAME'],
  $item['FEEDER_NAME']);
  foreach($item as $key => $val) {
    if(!in_array($key, array('REJECT_RATE', 'MACHINE_NAME', 'FEEDER_NAME', 'REJECT_QTY'))) {
      printf("    %s ( %s )\n", $key, 100*$val/$item['REJECT_QTY']);
    }
  }
}

Answer 4

利用 foreach 循环遍历数组中的每个对象并相应地输出它们。应修改下面的示例以适合您的样式，但它应该为您提供入门基础：

<table>
<thead>
    <tr><th>Item</th><th>Value</th></tr>
</thead>
<tbody>
<?php
foreach ($myArray as $k => $v){
    echo "<tr><td>$k</td><td>$v</td></tr>";
}
?>
</tbody>
</table>

Answer 5

使用 foreach 迭代这些值并根据需要格式化输出字符串。

foreach( $your_array as $id => $details ) {
    foreach( $details as $key => $value ) {
        //format your desired output
    }
}
