添加到循環結尾的數組

Question

我在這段代碼的末尾想要的是一個數組，它不斷添加給一個數組中的所有$ id。

當前代碼在數組中執行15，然後被接下來的15個項目覆蓋。我想能夠在數組中有30個項目的代碼末尾有一個數組。

我下面的代碼：

$idArray = array(); 

do { 
$html = file_get_html($url); 
parseItems($html, $dbh); 
sleep_flush($chunks=1); // ADJUST LATER 
} 

while (!empty($html->find('span[class=load-more-message]', 0))); 

$html->clear(); 
unset($html); 

// ------------------------------------------------- 

function parseItems($html, $dbh) { 

foreach($html->find('div.product-stamp-inner') as $content) { 

$detail['itemid'] = filter_var($content->find('a.product-title-link', 0)->href, FILTER_SANITIZE_NUMBER_FLOAT); 
$id = $detail['itemid']; 
$idArray[] = $id; //Counting and adding items to an array 

$detail['title'] = $content->find('span.title', 0)->plaintext; 
$description = $detail['title']; 

if (!tableExists($dbh, $id, $detail)) { 
    echo $id . " > " . $description . "> Table does not exist >"; 
    createTable($dbh, $id, $description); 
    insertData($dbh, $id, $detail); 
    echo "<br>"; 
} else { 
    echo $id . " > " . $description . "> Table already exists >"; 
    checkData($dbh, $id, $detail); 
    echo "<br>"; 
     } 
    } 
    print_r($idArray); 
} 

Answer 1

這是因爲你重新定義你的$ idArray這裏：

$idArray = array(); 

你可將該類的您$ idArray全球/成員變量..或您可以通過參考傳遞參數：

$idArray = array(); 

do { 
$html = file_get_html($url); 
parseItems($html, $dbh, $idArray); 
sleep_flush($chunks=1); // ADJUST LATER 
} 

while (!empty($html->find('span[class=load-more-message]', 0))); 

$html->clear(); 
unset($html); 

// ------------------------------------------------- 

function parseItems($html, $dbh, &$idArray) { 

foreach($html->find('div.product-stamp-inner') as $content) { 

$detail['itemid'] = filter_var($content->find('a.product-title-link', 0)->href, FILTER_SANITIZE_NUMBER_FLOAT); 
$id = $detail['itemid']; 
$idArray[] = $id; //Counting and adding items to an array 

$detail['title'] = $content->find('span.title', 0)->plaintext; 
$description = $detail['title']; 

if (!tableExists($dbh, $id, $detail)) { 
    echo $id . " > " . $description . "> Table does not exist >"; 
    createTable($dbh, $id, $description); 
    insertData($dbh, $id, $detail); 
    echo "<br>"; 
} else { 
    echo $id . " > " . $description . "> Table already exists >"; 
    checkData($dbh, $id, $detail); 
    echo "<br>"; 
     } 
    } 
    print_r($idArray); 
}
