Question

这是一个编辑过的代码，其中先生。 Paulo Rodrigues，php curl用于获取指定网页中的条目或数据。它将保存在file.txt中。打开文件然后获取每个条目的数据然后循环，以便插入条目中所需的所有数据。

$ch = curl_init("http://www.uniprot.org/uniprot/?query=(annotation%3a(type%3asignal+confidence%3aexperimental))+AND+reviewed%3ayes&sort=score&limit=10&format=txt");
$fp = fopen("file.txt", "w");

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

curl_exec($ch);


while (!feof($fp))
{

$array = array();
$index = -1;

foreach ($fp as $line) {
if (preg_match('#^ID#', $line)) {
    $index++;
}

$array[$index][] = $line;
}

foreach ($array as $block) {
$fields = array();

foreach ($block as $item) {
    if (preg_match('#^ID\s+(.*?)\s#', $item, $matches)) {
        print_r($fields['prot_name'] = $matches[1]);
        echo "&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp";
    } 
   else if (preg_match('#^OC\s+(Eukaryota)#', $item, $matches)) {
       print_r($fields['tax_lin'] = $matches[1]);
         echo "&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
             &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp";
    } 
    else if (preg_match('#LOCATION:\sMembrane;\s(.*?)\s#', $item, $matches)) {
        print_r($fields['sub_loc'] = $matches[1]); 

    } 

    }

    echo "<br />";

    if (!empty($fields)) {
    $f = implode(', ', array_keys($fields));
    $v = "'" . implode("', '", $fields) . "'";

    $sql = "INSERT INTO swissprot ($f) VALUES($v)";
    mysql_query($sql) or die(mysql_error());
    }


   }
 }

curl_close($ch);
fclose($fp);

问题是有一个警告显示：“警告：此行中为foreach（）提供的参数无效。可能是什么问题？

foreach ($fp as $line) {
if (preg_match('#^ID#', $line)) {
    $index++;
}

$array[$index][] = $line;
}

你可以试试这个：

$webpagedata = file('http://www.uniprot.org/uniprot/?query=annotation%3a%28type%3asignal+confidence%3aexperimental%29+reviewed%3ayes&sort=score&limit=10&format=txt');

$array = array();
$index = -1;

foreach ($webpagedata as $line) {
    if (preg_match('#^ID#', $line)) {
        $index++;
    }

    $array[$index][] = $line;
}

foreach ($array as $block) {
    $fields = array();

    foreach ($block as $item) {
        if (preg_match('#^ID\s+(.*?)\s#', $item, $matches)) {
            $fields['prot_name'] = $matches[1];
        } else if (preg_match('#^OC\s+(Eukaryota)#', $item, $matches)) {
            $fields['tax_lin'] = $matches[1];
        } else if (preg_match('#LOCATION:\sMembrane;\s(Single-pass)#', $item, $matches)) {
            $fields['sub_loc'] = $matches[1];
        }
    }

    if (!empty($fields)) {
        $f = implode(', ', array_keys($fields));
        $v = "'" . implode("', '", $fields) . "'";

        $sql = "INSERT INTO spdb ($f) VALUES($v)";
        mysql_query($sql) or die(mysql_error());
    }
}
