문제가 foreach을 함께하다 . 안에있는 tr을 어떻게 건너 뛸 수 있습니까? ID가 "specialTbl"인 테이블에 7 개의 행이 있습니다. 하지만 for each은 runsOn이라는 테이블을 반복하면서 json에서 14 개의 행을 반환합니다.

어떻게 당신은 PHP's DOM parser을 사용할 수

Answer 1

다음과 같이 Xpath와 함께 DomDocument를 사용하는 것이 더 쉬울 것입니다. DomDocument는 이미 PHP5에 있습니다. 그것은 당신에게 원하는 출력을 줄 것이다.

$doc = new DOMDocument(); 
$doc->loadHTML($html); 
$xpath = new DOMXpath($doc); 
$response["response_code"] = 200; 
$response["rows"] = array(); 
$trs = $xpath->query("//table[@id='specialTbl']/tbody/tr"); // all child tr's in all child tbody's in any table that has id 'specialTbl' 
foreach ($trs as $tr) { 
    $post = array(); 
    $tds = $xpath->query("td", $tr); // all child td's in $tr 
    foreach ($tds as $key => $td) { 
     $post["td" . ++$key] = $td->textContent; 
    } 
    array_push($response["rows"], $post); 
} 
$json_content = json_encode($response); 
echo $json_content; 

그러나 당신은 또한 http://simplehtmldom.sourceforge.net/manual.htm을 계속 사용하고 CSS와 같은 선택기 사용할 수 있습니다 (테스트되지 않은 코드를, 나는 simplehtmldom이없는) :

기능을 무엇

$html= str_get_html($html); 
$response["response_code"] = 200; 
$response["rows"] = array(); 
$trs = $html->find("table#specialTbl>tbody>tr"); 
foreach ($trs as $tr) { 
    $post = array(); 
    $tds = $tr->children(); 
    foreach ($tds as $key => $td) { 
     $post["td" . ++$key] = $td->innertext; 
    } 
    array_push($response["rows"], $post); 
} 
$json_content = json_encode($response); 
echo $json_content; 

Answer 2

(4) TD 내부 테이블을 통해 반복하지 않도록하고, tr 항목을 검색하기 전에, 그것은 HTML 구조에서 모든 중첩 된 테이블 밖으로 치기 얻을 수 있습니다

을

// Parse the HTML into a DOM object & find the table by ID 
$doc = new DOMDocument(); 
$doc->loadHTML($html); 
$table = $doc->getElementById('specialTbl'); 

// Remove all nested TRs from the DOM table object 
$nested = $table->getElementsByTagName('table'); 
foreach ($nested as $element) 
{ 
    // Remove the TRs from thi nested table 
    foreach ($element->getElementsByTagName('tr') as $tr) 
     $tr->parentNode->removeChild($tr); 
} 

// Now when we search through TRs, we only get the top level ones 
$rows = $table->getElementsByTagName('tr'); 
$response = array(); 
foreach ($rows as $row) 
{ 
    // Collect the values of this row's TDs 
    $tds = array(); 
    foreach ($row->getElementsByTagName('td') as $td) 
    { 
     $tds[] = trim($td->nodeValue); 
    } 

    // Add this row to the response 
    $response['rows'][] = $tds; 
} 

// Add extra response details 
$response['response_code'] = 200; // You shouldn't need to explicitly send this 
$json = json_encode($response); 

// Output JSON 
header('Content-type: application/json'); // Use the correct MIME type 
echo $json;
