php - 检查数组中是否存在某个值，如果不存在，则检查下一个值并确保以前的值不会出现

Question

好的，我有一个名为 $arraymaster 的数组，它基本上是一个教育代码数组(从最高到最低):

$arrayedumaster=array("P H D", "Post Graduate", "Professional", "Graduate", "Technical", "ITI", "Under Graduate", "H S C Passed", "S S C Passed", "Upto Ninth", "Upto Fifth", "No Schooling");

现在有第二个数组，列出了我从数据库中获得的个人资格:

$arrayedu=explode(',', $edudetail);

$arrayedu 的一些示例是(一个人可以拥有多个资格):

• 毕业生、HSC 通过、毕业生、专业人士、专业人士
• 专业，通过 SSC
• 专业、技术研究生

等等。现在我必须确定个人的最高资格(基于 $arraymaster)>>，然后在此基础上从 $arrayedu 执行一些操作。目前我正在这样做:

 if(in_array("P H D", $arrayedu){
  $educode=1;
 }
 elseif(in_array("Post Graduate", $arrayedu) && !in_array("P H D",$arrayedu)){
 $educode=2;
}
 elseif(in_array("Professional", $arrayedu) && !in_array("P H D", $arrayedu) 
&& !in_array("Post Graduate", $arrayedu)){
 $educode=3;
}
elseif(in_array("Graduate", $arrayedu) && !in_array("Professional", 
$arrayedu) && !in_array("P H D", $arrayedu) && !in_array("Post Graduate", 
$arrayedu)){
$educode=4;
}

等等。所以基本上我想从 $arrayedu 获得最高资格，是否有一些更简单的方法可以做到这一点？

Answer 1

使用array_intersect和current函数的解决方案:

$arrayedumaster = [
    "P H D", "Post Graduate", "Professional", "Graduate", "Technical", "ITI", "Under Graduate",
    "H S C Passed", "S S C Passed", "Upto Ninth", "Upto Fifth", "No Schooling"
];
$arrayedu = ["Graduate", "HSC Passed", "Graduate", "Professional", "Professional"];

$highest_edu = current(array_intersect($arrayedumaster, $arrayedu));
print_r($highest_edu);

输出:

Professional
