$dogruA = array("1", "2", "3", "4", "5", "6", "7", "8", "9", "10");
$yanlisA = array("3", "4", "7", "8", "10");
shuffle($dogruA);
shuffle($yanlisA);
foreach ($dogruA as $dogru) :
if ($dogru != '') {
?>
<input type="checkbox" name="answerSik[]"
value="<?php echo $dogru; ?>"><?php echo $dogru; ?>
<?php
}
endforeach;
foreach ($yanlisA as $yanlis) :
if ($yanlis!= '') { ?>
<input type="checkbox" name="answerSik[]"
value="0"><?php echo $yanlis; ?>
<?php
}
endforeach;
我如何结合这两个foreach?
我试过这些:
foreach( $dogruA as $dogru and $yanlisA as $yanlis)
和
foreach (array_combine($dogruA, $yanlisA) as $dogru => $yanlis) {
但我没有成功。 我如何使用方法?

您可以使用
foreach (array_merge($dogruA, $yanlisA) as $dogru => $yanlis) {
Array_combine具有与此处所需的功能不同的功能
如上所述,如果您只需要唯一值,则应使用此
foreach (array_unique(array_merge($dogruA, $yanlisA)) as $dogru => $yanlis) {

您可以先合并数组,例如
$new_array = array_merge($dogruA, $yanlisA);
然后在使用array_unique()方法传递给foreach后,它会处理数组重复值,
foreach(array_unique($new_array) as $single){
echo $single;
}
