Question

这是代码：

$dat = getContents($id, $session);
foreach($dat['data']['followings'] as $gg){
    $fid = $gg['fid'];
    $f = follow($fid, $session, $atok);
    echo $f['data']['credits'] . "\n";
}

当我运行此脚本时，我的硬币会得到结果

例如：

11 12

那么，如何重复代码直到我得到50硬币或100或类似的东西？

因为在PHP上只给我2个结果。我可以使它达到10或50或100，但我可以使用COPY PASTE这些脚本。你知道吗？

这是我重复此代码的方式：

$dat = getContents($id, $session);
foreach($dat['data']['followings'] as $gg){
    $fid = $gg['fid'];
    $f = follow($fid, $session, $atok);
    echo $f['data']['credits'] . "\n";
} 

$dat = getContents($id, $session);
foreach($dat['data']['followings'] as $gg){
    $fid = $gg['fid'];
    $f = follow($fid, $session, $atok);
    echo $f['data']['credits'] . "\n";
}

$dat = getContents($id, $session);
foreach($dat['data']['followings'] as $gg){
    $fid = $gg['fid'];
    $f = follow($fid, $session, $atok);
    echo $f['data']['credits'] . "\n";
}

所以我可以得到6个结果。我的问题是如何制作代码而不复制粘贴此代码。

Answer 1

Foreach是一个读取数组所有索引的循环，它会重复自身，直到读取该数组的所有索引。

Answer 2

for($i = 0; $i < 10; $i++){
    $dat = getContents($id, $session);
    foreach ($dat['data']['followings'] as $gg){
        $fid = $gg['fid'];
        $f = follow($fid, $session, $atok);
        echo $f['data']['credits'] . "\n";
    }
}

Answer 3

$dat = getContents($id, $session);
$counter = 0;
while ($counter < 100) {
    foreach ($dat['data']['followings'] as $gg){
        $fid = $gg['fid'];
        $f = follow($fid, $session, $atok);
        $counter++
        echo $f['data']['credits'] . "\n";
    }
}
