單個foreach中的多個數組

Question

今天我有一個瘋狂的夜晚，因爲我無法解決它，我無法找到任何解決方案，所有我能找到的是一個解決方案，如果它只有2個陣列，但我有超過2個。我的問題是有可能的在一個foreach中循環多個數組？下面的代碼適用於branchname而不適用於其他陣列

<?php 

$branchNameList = array("branch_name1", "branch_name2", "branch_name3", "branch_name4"); 
$branchPhotoList = array("photo1", "photo2", "photo3", "photo4"); 
$branchAddList = array("address1", "address2", "address3", "address4"); 
$branchMapList = array("maplink1", "maplink2", "maplink3", "maplink4"); 
$branchTelList = array("branch_tel1", "branch_tel2", "branch_tel3", "branch_tel4"); 

foreach ($branchNameList as $branchName) { 
    echo '<div> 
       '.$params->get($branchPhoto).' 
      </div> 
        <h2> 
         '.$params->get($branchName).' 
        </h2> 
        <div> 
         <a href="'.$params->get($branchMap).'">'.$params->get($branchAdd).'</a> 
        </div> 
        <div> 
         <a href="#">'.$params->get($branchTel).'</a> 
       </div>'; 
       } 
?> 

請問有人可以幫我嗎？

謝謝

您是否期待這樣？確保爲循環中運行時，所有其他陣列count是一樣的，否則你將得到Notice error

Try this code snippet here

<?php 
ini_set('display_errors', 1); 
$branchNameList = array("branch_name1", "branch_name2", "branch_name3", "branch_name4"); 
$branchPhotoList = array("photo1", "photo2", "photo3", "photo4"); 
$branchAddList = array("address1", "address2", "address3", "address4"); 
$branchMapList = array("maplink1", "maplink2", "maplink3", "maplink4"); 
$branchTelList = array("branch_tel1", "branch_tel2", "branch_tel3", "branch_tel4"); 
for($x=0;$x<count($branchNameList);$x++) 
{ 
    if(!empty($branchNameList[$x])) 
    { 
     echo $branchNameList[$x]; 
     echo PHP_EOL; 
    } 
    if(!empty($branchPhotoList[$x])) 
    { 
     echo $branchPhotoList[$x]; 
     echo PHP_EOL; 
    } 
    if(!empty($branchAddList[$x])) 
    { 
     echo $branchAddList[$x]; 
     echo PHP_EOL; 
    } 
    if(!empty($branchMapList[$x])) 
    { 
     echo $branchMapList[$x]; 
     echo PHP_EOL; 
    } 
    if(!empty($branchTelList[$x])) 
    { 
     echo $branchTelList[$x]; 
     echo PHP_EOL; 
    } 
} 

解決方案2：

<?php 
ini_set('display_errors', 1); 
$branchNameList = array("branch_name1", "branch_name2", "branch_name3", "branch_name4"); 
$branchPhotoList = array("photo1", "photo2", "photo3", "photo4"); 
$branchAddList = array("address1", "address2", "address3", "address4"); 
$branchMapList = array("maplink1", "maplink2", "maplink3", "maplink4"); 
$branchTelList = array("branch_tel1", "branch_tel2", "branch_tel3", "branch_tel4"); 
$completeData= array_merge(
     array("branchNameList"=>$branchNameList), 
     array("branchPhotoList"=>$branchPhotoList), 
     array("branchAddList"=>$branchAddList), 
     array("branchMapList"=>$branchMapList), 
     array("branchTelList"=>$branchTelList) 
     ); 

for($x=0;$x<count($completeData["branchNameList"]);$x++) 
{ 
    if(empty($completeData["branchNameList"][$x])|| 
     empty($completeData["branchPhotoList"][$x])|| 
     empty($completeData["branchAddList"][$x])|| 
     empty($completeData["branchMapList"][$x])|| 
     empty($completeData["branchTelList"][$x])) 
    { 
     continue; 
    } 
    else 
    { 
     //do what you want to do. 
    } 
}

如果你可以肯定您的陣列總是具有相同的計數並且它們都是相關的：

<?php 

error_reporting(E_ALL); 
ini_set("display_errors", 1); 

$branchNameList = array("branch_name1", "branch_name2", "branch_name3", "branch_name4"); 
$branchPhotoList = array("photo1", "photo2", "photo3", "photo4"); 
$branchAddList = array("address1", "address2", "address3", "address4"); 
$branchMapList = array("maplink1", "maplink2", "maplink3", "maplink4"); 
$branchTelList = array("branch_tel1", "branch_tel2", "branch_tel3", "branch_tel4"); 

foreach($branchNameList as $key => $value){ /* we access 1st level */ 
echo '** key: '.$key.'/value: '.$value.' **<br/>'; 
echo $branchPhotoList[$key].'<br/>'; /* then we use 1st level key */ 
echo $branchAddList[$key].'<br/>'; 
echo $branchMapList[$key].'<br/>'; 
echo $branchTelList[$key].'<br/>'; 
} 

?>

在這種情況下，您應該使用常規for循環代替foreach。

$branchNameList = array("branch_name1", "branch_name2", "branch_name3", "branch_name4"); 
$branchPhotoList = array("photo1", "photo2", "photo3", "photo4"); 
$branchAddList = array("address1", "address2", "address3", "address4"); 

for ($i = 0; $i < count($branchNameList); ++$i) { 
    echo $branchNameList[$i] . "<br>"; 
    echo $branchPhotoList[$i] . "<br>"; 
    echo $branchAddList[$i] . "<br>"; 
} 

但是，你會遇到的問題，如果某些數組的比你的條件使用循環（這裏：$branchNameList）中少了一個元素。至少有兩種方法，你可以解決這個問題：

1. 找出最小這些陣列，並使用其長度條件。
2. 使用最大數組的長度作爲條件並在循環中添加安全措施。

讓我們來看看第一個選項的例子：

/* ... */ 

$minLength = min(
    count($branchNameList), 
    count($branchPhotoList), 
    count($branchAddList) 
); 

for ($i = 0; $i < $minLength; ++$i) { 
    /* ... */ 
} 

而一個用於第二個選項：

/* ... */ 

$maxLength = max(
    count($branchNameList), 
    count($branchPhotoList), 
    count($branchAddList) 
); 

for ($i = 0; $i < $maxLength; ++$i) { 
    if (isset($branchPhotoList[$i]) { 
     echo $branchNameList[$i] . "<br>"; 
    } 
    if (isset($branchPhotoList[$i]) { 
     echo $branchPhotoList[$i] . "<br>"; 
    } 
    if (isset($branchPhotoList[$i]) { 
     echo $branchAddList[$i] . "<br>"; 
    } 
}
