PHP从数组中提取值并将它们还原到另一个数组中

问题描述：

I have an Array of values pulled from a mysql table of the form:

$name_ids = EMP-646
            EMP-545
            EMP-12
            CLIENT-36
            CLIENT-43
            CLIENT-5

I would like to identify EMP and CLIENT as separate data and then extract only the integer values and then store them into separate variables. For example:

$emp_id =    646
             545
             12

$client_id = 36
             43 
             5

Here is my attempt at it but I am unable to print the desired results (not sure if my logic is correct):

$name_ids = array($_SESSION['INVITED_NAMES']);

foreach($name_ids[0] as $name_id){
  if(stripos($name_id, 'EMP') !== false){ 
    $emp_id = preg_replace("/[^0-9]/","",$name_id);
  }
  elseif(stripos($name_id, 'CLIENT') !== false){ 
    $client_id = preg_replace("/[^0-9]/","",$name_id);
  }

  echo $emp_id.' '; //both results need to happen at this stage in the `foreach` loop.
  echo $client_id.' ';              
}

One thing to note is I need the results to appear where they are due to other code that is dependent on this location. With the present code this is the results I get:

646 545 12 36 12 43 12 5 12

The error appears at the first if statement($emp_id), when a value is false it returns the last int of a true value until the loop is through. Any help is greatly appreciated.

我从表单的mysql表中提取了一个值数组： p> $ name_ids = EMP-646 EMP-545 EMP-12 CLIENT-36 CLIENT-43 CLIENT-5 code> pre>

我想将EMP和CLIENT识别为单独的数据，然后仅提取整数值，然后将它们存储到单独的变量中。例如： p>


  $ emp_id = 646 
 545 
 12 
 
 $ client_id = 36 
 43 
 5 
  code>  pre  > 
 
 这是我的尝试，但我无法打印出所需的结果（不确定我的逻辑是否正确）： p> 
 
 
  $ name_ids =  array（$ _ SESSION ['INVITED_NAMES']）; 
 
foreach（$ name_ids [0] as $ name_id）{
 if（stripos（$ name_id，'EMP'）！== false）{
 $ emp_id =  preg_replace（“/ [^ 0-9] /”，“”，$ name_id）; 
} 
 elseif（stripos（$ name_id，'CLIENT'）！== false）{
 $ client_id = preg_replace（“  / [^ 0-9] /“，”“，$ name_id）; 
} 
 
 echo $ emp_id。'  “;  //两个结果都需要在`foreach`循环的这个阶段发生。
 echo $ client_id。'  “;  
} 
  code>  pre> 
 
 需要注意的一点是，我需要将结果显示在依赖于此位置的其他代码的位置。 使用当前代码，这是我得到的结果： p> 
 
 
  646 545 12 36 12 43 12 5 12 
  code>  pre> 
 
 错误出现在第一个if语句（ $ emp_id  code>），当值为false时，它返回true值的最后一个int，直到循环结束。 任何帮助是极大的赞赏。   p> 
  div>

Here it is working: https://eval.in/84445

Relevant code:

$emp_ids = array();
$client_ids = array();

$name_ids = array('EMP-646',
            'EMP-545',
            'EMP-12',
            'CLIENT-36',
            'CLIENT-43',
            'CLIENT-5');

var_dump($name_ids);            

foreach($name_ids as $name_id){
  if(stripos($name_id, 'EMP') !== false){ 
    $emp_id = preg_replace("/[^0-9]/","",$name_id);
    array_push($emp_ids, $emp_id);
  }
  elseif(stripos($name_id, 'CLIENT') !== false){ 
    $client_id = preg_replace("/[^0-9]/","",$name_id);
    array_push($client_ids, $client_id);
  }

}

echo "Emp_ids are: ";
var_dump($emp_ids);

echo "Client_ids are: ";
var_dump($client_ids);

I just created arrays to store the values, and pushed them in.
