require('simple-parser.php');
$html = <<<EOF

为每个循环生成一个json
$html= str_get_html($html);
$table =$html->find('table#specialTbl',0) ;
$response["response_code"] = 200;
$response["rows"] = array();
foreach($table->find('tr') as $key=>$value) {
$post["td1"]= trim(strip_tags($value->find('td',0)->plaintext));
$post["td2"]= trim(strip_tags($value->find('td',1)->plaintext));
$post["td3"]= trim(strip_tags($value->find('td',2)->plaintext));
$post["td4"]= trim(strip_tags($value->find('td',3)->plaintext));

$post["td6"]= trim(strip_tags($value->find('td',5)->plaintext));
array_push($response["rows"], $post);
}
$json = json_encode($response);
echo $json_content;

问题在于foreach。如何跳过tr内的td。我在表中有7行，ID为“specialTbl”。但是for each在json中返回14行，因为它循环遍历名为runsOn的表。
如何避免在td（4th）内循环遍历表？
答案 0 :(得分：1)
您必须在array_push循环外使用foreach。
foreach($table->find('tr') as $key=>$value) {
$post["td1"]= trim(strip_tags($value->find('td',0)->plaintext));
$post["td2"]= trim(strip_tags($value->find('td',1)->plaintext));
$post["td3"]= trim(strip_tags($value->find('td',2)->plaintext));
$post["td4"]= trim(strip_tags($value->find('td',3)->plaintext));
$post["td5"]= trim(strip_tags($value->find('td',4)->plaintext));
$post["td6"]= trim(strip_tags($value->find('td',5)->plaintext));
}
array_push($response["rows"], $post);
