数组运用技巧分享002

1.数组累计金额技巧

//判断新数组的key是否存在和原数组一样的key
$jobArray = 
Array
(
    [0] => Array
        (
            [0] => 641
            [1] => 唯道智行
            [2] => 朝阳区
            [3] => 7.00
            [job_id] => 13
        )

    [1] => Array
        (
            [0] => 641
            [1] => 唯道智行
            [2] => 朝阳区
            [3] => 8.00
     [job_id] => 14
        )

    [2] => Array
        (
            [0] => 641
            [1] => 唯道智行
            [2] => 朝阳区
            [3] => 10.00
     [job_id] => 15
        )

)

$postArry = array();
foreach($jobArray as $job) {

    if(isset($postArry[ $job['user_id'].','. $job['company'].','. $job['address']])) {

 $postArry[ $job['user_id'].','. $job['company'].','. $job['address']]['amount'] += $job['amount'];
 $postArry[ $job['user_id'].','. $job['company'].','. $job['address']]['job_id'] .= ',' . $job['job_id'];

    }else {

        $postArry[ $job['user_id'].','. $job['company'].','. $job['address']]['amount'] = $job['amount'];
        $postArry[ $job['user_id'].','. $job['company'].','. $job['address']]['job_id'] = $job['job_id'];

    }
}

Array(
    '641,唯道智行,朝阳区' => array( 'amount' => 25, 'job_id' => '13,14,15'  ),
     
);

2.数组金额值的  拼接

    $num = 0;$i = 0;
       $numArray = array();
       if (count($jobArray)>0) {
           foreach($jobArray as $v){
              if ($v['receipt_amount'] < 500){
                    $num++;
              }else {
                  $i++;
              }
           }
        }
        $numArray = array('pay'=>$num,'normal'=>$i);

//数组金额的值拼接
//金额
$array1 = array(
    '4' => '20.00',
 '5' => '20.00',
 '9,10,12' => '500.00',
 '15,20,32' => '1500.00',
);

$paidanIdFrom1 = '20001';
$paidanIdTo1 = '20010';

$paidanIdFrom2 = '30001';
$paidanIdTo2 = '30010';

$i = 0;
$j = 0;
for($array1 as $key => $value) {
    if($value >= 500) {
  $array2[$key] = $paidanIdFrom1 + $i;
  $i++;

 }else {
  $array2[$key] = $paidanIdFrom2 + $j;
  $j++;
 }
}

//快递单号
$array2 = array(
    '4' => '20001',
 '5' => '20002',
 '9,10,12' => '30001',
 '15,20,32' => '30002',
);
