Php 检查数组中是否存在某些值，如果不存在，则检查下一个值，并确保前一个值不会出现

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）：

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的一些例子是（一个人可以有多种资格）：

• 研究生，HSC通过，研究生，专业，专业
• 专业，SSC通过
• 研究生、专业人员、技术人员

等等。 现在，我必须确定一个人的最高资格（基于$arraymaster）>>然后在此基础上从$arrayedu执行一些操作。目前我正在做这件事，因此：

 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。所以我基本上是想从$arrayedu那里获得最高的资格，有没有更简单的方法

使用

array\u intersect

和

current

功能的解决方案：

$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

RomanPerekhrest已经提供了完美的一行答案，但这种方法可能会有所启发：

$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"
];

$highestedu = count($arrayedumaster);
foreach ( $arrayedu as $value ) {
  if ( ($key = array_search($value, $arrayedumaster)) !== false ) {
    $highestedu = min($key, $highestedu);
  }
}

print_r($arrayedumaster[$highestedu]);

请尝试以下排序：

$data = array(
    "Graduate", "H S C Passed", "Graduate", "Professional", "Professional"
);

$sortingArr = 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", "ddd");

$result = array(); // result array
foreach($sortingArr as $val){ // loop
    $key = array_search($val, $data);
    if(in_array($val, $data)) {
        $result[$key] = $val; // adding values
    }

}
print_r($result); // print results

---

就是这样！谢谢。

$data = array(
    "Graduate", "H S C Passed", "Graduate", "Professional", "Professional"
);

$sortingArr = 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", "ddd");

$result = array(); // result array
foreach($sortingArr as $val){ // loop
    $key = array_search($val, $data);
    if(in_array($val, $data)) {
        $result[$key] = $val; // adding values
    }

}
print_r($result); // print results
