Question

出于某种奇怪的原因

if(in_array("January", $season)){

当我指定＆＃34; 1月＆＃34;在in_array中它匹配数组值。但是，当我使用包含单词January的$search_string时，它并不匹配。出现这种情况的原因是什么我在单词之前和之后删除了空格，但它仍然不匹配。

$season = array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");

print_r($lines);
Array ( [0] => January - March, November
[1] => 2 travelers:  Adult: $9,499 Child: $7,125
[2] => 4 travelers:  Adult: $8,315 Child: $6,235
[3] => 6 travelers:  Adult: $7,975 Child: $5,980
[4] => June - October, December
[5] => 2 travelers:  Adult: $10,799 Child: $8,099
[6] => 4 travelers:  Adult: $9,835 Child: $7,375
[7] => 6 travelers:  Adult: $9,535 Child: $7,150
)

var_dump($lines);
array(8) { [0]=> string(47) "January - March, November
" [1]=> string(48) "2 travelers:  Adult: $9,499 Child: $7,125
" [2]=> string(49) "4 travelers:  Adult: $8,315 Child: $6,235
" [3]=> string(47) "6 travelers:  Adult: $7,975 Child: $5,980
" [4]=> string(46) "June - October, December
" [5]=> string(49) "2 travelers:  Adult: $10,799 Child: $8,099
" [6]=> string(49) "4 travelers:  Adult: $9,835 Child: $7,375
" [7]=> string(47) "6 travelers:  Adult: $9,535 Child: $7,150
"
}

     foreach($lines as $key => $value){
         $search_string = explode("-", $value);
         $search_string = $search_string[0];
         echo "--"; echo $search_string = trim($search_string); echo "--"; //  --January-- 

         if(in_array("January", $season)){
             echo "Match found";
         } else {
             echo "Match not found";
         }
     }

这是我到目前为止所得到的：

@spirit，这里是创建数组行的地方

     $lines = array();
     foreach(preg_split("/((\r?\n)|(\r\n?))/", $seasonal_price) as $line){
         // Only add to array for lines with content
         if(trim($line)!="") $lines[] = $line;
     }

这是我的最终代码和最终输出：

             //Seasonal price
             $seasonal_price = $row['post_content'];

             //Split individual lines into an array
             $lines = preg_split("/[\r\n]+/", strip_tags($seasonal_price), -1, PREG_SPLIT_NO_EMPTY);

             //Define seasons
             $season = array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");

             echo "<br>";
             foreach ($lines as $key => $value) {

                     $search_string = explode("-", $value);
                     $search_string = trim($search_string[0]);

                     if (in_array($search_string, $season)) {
                         echo '<i class="fa fa-money"></i>&nbsp;<span class="head" style="font-weight:bold;">';echo$value;echo'</span>';
                     } else {
                         echo '<span>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;';echo$value;echo'</span>';
                     }
                     echo "<br>";
            }

        ?>

代码部分反映了标签 1月和6月

下图中的结果

问题是由于浏览器窗口中的html容器，我没有看到隐藏的<strong>标记。我没有看到标签，它被解析为html标签。

尝试以下方法：

$lines = preg_split("/[\r\n]+/", strip_tags($seasonal_price), -1, PREG_SPLIT_NO_EMPTY);

foreach ($lines as $key => $value) {
    $search_string = explode("-", $value);
    $search_string = trim($search_string[0]);
    //echo "--"; echo $search_string = trim($search_string); echo "--"; //  --January-- 

    if (in_array($search_string, $season)) {
        echo "Match found";
    } else {
        echo "Match not found";
    }
    echo "\r\n";
}

输出：

Match found
Match not found
Match not found
Match not found
Match found
Match not found
Match not found
Match not found

就像你的输入$lines一样。

更新：正如我们在聊天中发现的那样，填充$seasonal_price的数据来自数据库并且包含：

<strong>January - March, November</strong><br/> 

2 travelers:  Adult: $9,499 Child: $7,125<br/> 

4 travelers:  Adult: $8,315 Child: $6,235<br/> 

6 travelers:  Adult: $7,975 Child: $5,980<br/> 

<strong>June - October, December</strong><br/> 

2 travelers:  Adult: $10,799 Child: $8,099<br/> 

4 travelers:  Adult: $9,835 Child: $7,375<br/> 

6 travelers:  Adult: $9,535 Child: $7,150<br/>

所以我在我的回答中添加了strip_tags()来电

php in_array搜索php数组值不起作用
