Question

我有一个包含多个值的字符串。新行被识别为|符号。 |之间的值永远在一起。

现在，我正在尝试例如IKK和Homo sapiens是否存在于该行中，以返回该行中的其他值（96，NC_000001，IKK，核因子抑制剂，IKK = IKKI）。

我使用explode函数来基于|分离字符串符号。但是，如果我现在再次使用爆炸功能，符号。我再次得到一个阵列。但如果我现在想要寻找智人和智人IKK并希望从同一行返回其他值，我卡住了。

我有以下字符串：

    $var = 'IKK ,Homo sapiens,96, NC_000001 , IKK , inhibitor of nuclear factor, 
    IKK = IKKI |GAL4 ,Saccharomyces cerevisiae,85588,NC_00114 , GAL4 ,0, GAL81
    |TRP ,Influenza HA,0,0,0,0,0|TES,Influenza HA,5,0,TES,0,0';

我的代码：

function terms($result){
    $result = (explode("|",$result));
    $final = array_unique($result);
    return $final;
}
$test = terms($var);
foreach ($test as $key => $value){
    echo "key: $key -- value: $value"."<br \>\n"; 
    $res = explode(",",$value);
    foreach ($res as $v){
        echo "tester: >> $v"."<br \>\n"; 
    }
}

我可能应该最终得到这样的东西。但我找不到办法到达那里。是否有可能获得这种结构？

if ($d[1] == "Homo sapiens" && $d[0] == "IKK"){
    $k = $d[2] # 96
    $s = $d[3] # NC_000001
 }

作为最终结果，我想将值96，NC_000001，IKK，核因子抑制剂，IKK = IKKI分别保存在一个单独的变量中。 $ number = 96 $ acc = NC_000001

对于这部分：

$filters = array("IKK", "Homo sapiens", .... "etc.");

$res = explode(",", $value);
$raw_filtered_res = array_filter($res, function ($v, $k) use($filters) {
    return !in_array($v, $filters);
}, ARRAY_FILTER_USE_BOTH);

if (count($res) !== count($raw_filtered_res)) {
    $filtered_res = array_values(array_diff($res, $raw_filtered_res));
    foreach ($filtered_res as $v) {
        echo "tester: >> $v"."<br \>\n"; 
    }
} else {
    break;
}

重写为

function hasAccess() {
        var dataObj = {
                "id" : $scope.groupId
            };
        $http.post('http://vlinux:9099/GetItems', dataObj).then(
                function(response) {
                    var result = response.data.result;
                        if(result.includes($scope.screenId)) {
                            return "ok";
                        } else {
                            return "nok";
                        }
                }).catch(function (error) {
                            // do something
                });
    }

我还没有运行它，所以这里可能存在语法错误......但是这样的事情可能适合你的需求吗？一个通用函数，用于将后续子字符串需要的术语数组传递给（后管道爆炸）

function filterList($str, $needed = []){
    //str is the pre-exploded comma delimited string
    //needed are the terms required for the string to pass
    //needed terms are filtered out of the returned array
    $found = true;
    if(! is_array($needed)) $needed = [$needed];
    foreach($needed as $needs_str){
        if(stripos($str, $needs_str) === false){
            $found = false;
        }
    }
    if($found){
        return array_filter(explode($str, ','), function($item) use ($needed){
            return ! in_array($item, $needed);
        });
    }
    return [];
}

然后使用

foreach ($test as $key => $value){
    $res = filterList($value, ["Homo sapiens","IKK"]);
    if(! empty($res)){
      //do something with res
    }
}

最初的问题之一是您的源数据在整个地方都包含空格，因此第一部分是向下拆分数据并array_walk()所有数据。 $filters用于一次处理每一行。

然后是根据您想要的字段过滤结果的情况。这是检查array_slice()数组是否与术语中的第一个字段相同（使用array_slice()来提取正确数量的字段）的情况，只需比较数组而不是单个字段，但是这假设字段的顺序相同。

然后使用输出，它会通过从前面移除过滤器来处理任何结果（再次使用$var = 'IKK ,Homo sapiens,96, NC_000001 , IKK , inhibitor of nuclear factor, IKK = IKKI |GAL4 ,Saccharomyces cerevisiae,85588,NC_00114 , GAL4 ,0, GAL81 |TRP ,Influenza HA,0,0,0,0,0|TES,Influenza HA,5,0,TES,0,0'; $terms = explode("|", $var); array_walk($terms, function (&$line) { $line = explode(",",$line); $line = array_map('trim', $line); }); $filters = ["IKK", "Homo sapiens"]; $output = array_filter($terms, function ($line) use ($filters) { return $filters == array_slice($line, 0,count($filters)); }); array_walk($output, function (&$line) use ($filters) { $line = array_slice($line, count($filters)); }); print_r($output);）。

results.push([[warrantyType],[warrantyStart],[warrantyEnd],[model]]);

由于涉及白色空间，我认为您无法比较值。请试试这个：

<?php

$var = 'IKK ,Homo sapiens,96, NC_000001 , IKK , inhibitor of nuclear factor, 
    IKK = IKKI |GAL4 ,Saccharomyces cerevisiae,85588,NC_00114 , GAL4 ,0, GAL81
    |TRP ,Influenza HA,0,0,0,0,0|TES,Influenza HA,5,0,TES,0,0';

function terms($result){
    $result = (explode("|",$result));
    $final = array_unique($result);
    return $final;
}


function compare_terms($res){
    $d = array_map('trim',$res);
    if ($d[1] == "Homo sapiens" && $d[0] == "IKK") {
        $k = $d[2] ; 
        echo $k ."<br \>\n"; // 96
        $s = $d[3] ; 
        echo $s ."<br \>\n"; // NC_000001
    }
}


$test = terms($var);
foreach ($test as $key => $value){
    echo "key: $key -- value: $value"."<br \>\n"; 
    $res = explode(",",$value);
    compare_terms($res);
}

在compare_terms函数中，我们使用以下方法对数组的每个值应用trim函数： $ d = array_map（＆＃39; trim＆＃39;，$ res）;

现在我们可以相应地比较值

PHP has a concept of nested arrays. Each element of an array can be an array, too. So explode and iterate the lines, then explode the fields. You can use array_map() to clean up the field values:

$data = 
  'IKK ,Homo sapiens,96, NC_000001 , IKK , inhibitor of nuclear factor, IKK = IKKI |'.
'GAL4,Saccharomyces cerevisiae,85588,NC_00114 , GAL4 ,0, GAL81|'.
'TRP ,Influenza HA,0,0,0,0,0|TES,Influenza HA,5,0,TES,0,0';

$values = [];
foreach (explode('|', $data) as $line) {
  $values[] = array_map(
    function($field) {
      return trim($field);
    },
    explode(',', $line)
  );
}

var_dump($values);

Output:

array(4) {
  [0]=>
  array(7) {
    [0]=>
    string(3) "IKK"
    [1]=>
    string(12) "Homo sapiens"
    [2]=>
    string(2) "96"
    [3]=>
    string(9) "NC_000001"
    [4]=>
    string(3) "IKK"
    [5]=>
    string(27) "inhibitor of nuclear factor"
    [6]=>
    string(10) "IKK = IKKI"
  }
  [1]=> ...

So now that you have that list of arrays you can use array_filter().

$filteredValues = array_filter(
  $values,
  function($fields) {
    return ($fields[0] === 'IKK' && $fields[1] === 'Homo sapiens');
  }
);

var_dump($filteredValues);

Or you use a foreach() to find the first line that matches your condition.

$searchedLine;
foreach ($values as $fields) {
  if ($fields[0] === 'IKK' && $fields[1] === 'Homo sapiens') {
    $searchedLine = $fields;
    break;
  }
}

var_dump($searchedLine);
