我應該如何將數組的值分爲偶數，奇數？

Question

問題

目前我的輸出來了這樣PNL測試1,10，PNL測試2.55，我想操縱它，它在兩個不同的變量存儲爲喜歡的字符串：

$車隊 =「PNL測試1，PNL測試2」;

$ amount =「10，55」;

請讓我知道我應該如何拆分上述格式。

代碼

while ($row1 = mysql_fetch_assoc($result)){ 
    $profit = 0; 
    $total = 0; 
    $loss = 0; 
    $final_array = ''; 
    $final_array .= $teams = $row1['t_name'].","; 
    $teams = explode(",", $teams); 

    $transact_money = $row1['pnl_amount']; 
    $pnl_results = $row1['pnl']; 

    $transact_money = explode("|", $transact_money); 
    $pnl_results = explode("|", $pnl_results); 
    for($i=0; $i<count($transact_money); $i++){ 
     if($pnl_results[$i]=='Profit'){ 
      $profit = $profit + $transact_money[$i]; 
     }else{ 
      $loss = $loss + $transact_money[$i]; 
     }//end if 
    }//end for.. 
    $team_profits = $profit - $loss.","; 
    $final_array .= $team_profits; 

    echo $final_array; 
} 

Answer 1

$s = "PNL testing 1,10,PNL testing 2,55"; 
$res = array(); 
$result = preg_match_all("{([\w\s\d]+),(\d+)}", $s, $res); 
$teams = join(', ', $res[1]); //will be "PNL testing 1, PNL testing 2" 
$amount = join(', ', $res[2]); //will be "10, 55" 

Answer 2

$string = "PNL testing 1,10,PNL testing 2,55,"; 
preg_match_all("/(PNL testing \d+),(\d+),/", $string, $result); 
$teams = implode(",", $result[1]); 
$amount = implode(",", $result[2]); 

Answer 3

少花哨比正則表達式，但更明顯：

$final_array = "PNL testing 1,10,PNL testing 2,55"; 

$final_array_array = explode(',', $final_array); 

$teams = array(); 
$amount = array(); 
$index = 0; 

foreach ($final_array_array as $item) { 
    switch ($index) { 
     case 0: 
      $teams[] = $item; 
      break; 
     case 1: 
      $amount[] = $item; 
    } 
    $index = 1-$index; 
}
