具有更多条件的PHP预测

Question

是否可以设置超过两个条件的foreach函数。下面的例子如下：

$stat_cps = $_POST['stat_cp'];
$acc_idss = $_POST['acc_ids'];

$string = 'NG';
foreach ($stat_cps as $url)
{
     if(strpos($string, $url) !== FALSE)
     {
          echo "One of the field is NG";
          return true;
     }
}

echo "All field is OK";

我想要的是：

如果$stat_cps或$acc_idss包含NG，那么echo "One of the field is NG";

在上面的代码中，它只适用于$stat_cps

*stat_cps和acc_idss来自单选按钮表单。

有人能给出建议吗？

Answer 1

可以使用array_merge组合两个数组：

http://php.net/manual/en/function.array-merge.php

$stat_cps = $_POST['stat_cp'];
$acc_idss = $_POST['acc_ids'];
$merged = array_merge($stat_cps,$acc_idss);
$string = 'NG';
foreach ($merged as $url)
{
     if(strpos($string, $url) !== FALSE)
     {
          echo "One of the field is NG";
          return true;
     }
}

这将删除重复的字符串键，但如果您只想要一个匹配项，则不应该出现这样的问题。

从你的评论试着做

 $stat_cps = $_POST['stat_cp'];
$acc_idss = $_POST['acc_ids'];
$merged = array_merge($stat_cps,$acc_idss);
$match = false;
$string = 'NG';
foreach ($merged as $url)
{
     if(strpos($string, $url) !== FALSE)
     {
          $match =  true;
     }
}

if($match){
       echo "One of the field is NG";
}else{
      echo "Everything is OK";
}

Answer 2

具有array_merge、implode和strpos函数的“单行”解决方案：

...
$hasNg = strpos("NG", implode(",", array_merge($stat_cps,$acc_idss)));
...

// check for 'NG' occurance
echo ($hasNg !== false)? "One of the field is NG" : "string 'NG' doesn't exists within passed data";

Answer 3

$stat_cps = $_POST['stat_cp'];
$acc_idss = $_POST['acc_ids'];

$process=0;
$string = 'NG';
foreach ($stat_cps as $url)
{
     if(strpos($string, $url) !== FALSE)
     {
          $process=1;
     }
}
foreach ($acc_idss as $url2)
{
     if(strpos($string, $url2) !== FALSE)
     {
          $process=1;
     }
}
if($process==1){
  echo "One of the field is NG";
  return true;
}
