file_get_contents沒有得到正確的文件

Question

我試圖建立一個腳本，將顯示一個新的基於狀態名稱的IP。 IP應該從與狀態名稱相同的文件中取得。然後它需要一個隨機IP並分配它（這是它應該如何工作）。

問題是它分配完全隨機IP並從隨機文件加載它們的IP，而不是從狀態名稱正確的文件中取出IP。

如何這應該工作：加州> california.txt>隨機IP

這是如何工作現在：加利福尼亞州>紐約/喬治亞州/得克薩斯州/ etc.txt>隨機IP

$state_content=["Alabama","Alaska","Arizona","Arkansas","California","Colorado","Connecticut","Delaware","Florida","Georgia","Hawaii","Idaho","Illinois","Indiana","Iowa","Kansas","Kentucky","Louisiana","Maine","Maryland","Massachusetts","Michigan","Minnesota","Mississippi","Missouri","Montana","Nebraska","Nevada","NewHampshire","NewJersey","NewMexico","NewYork","NorthCarolina","NorthDakota","Ohio","Oklahoma","Oregon","Pennsylvania","RhodeIsland","SouthCarolina","SouthDakota","Tennessee","Texas","Utah","Vermont","Virginia","Washington","WestVirginia","Wisconsin","Wyoming"]; 

$country_content=["UnitedStates", "UnitedKingdom", "Canada", "Australia", "Germany", "France", "Spain"]; 

$a = 0; 

function getStateContent($state_name) { 

    // checks do we already have content for this state 
    if(!isset($state_content[$state_name])) { 

     // generate file name 
     $file_name = "state/"; 
     $file_name .= str_replace(" ", "", ucwords($state_name)); 
     $file_name .= ".txt"; 

     $state_text = file_get_contents($file_name); 
     $state_content[$state_name] = explode("\n", $state_text); 
    } 

    return $state_content[$state_name]; 
} 

function getStateIpByName($state_name) { 
    $content = getStateContent($state_name); 
    return $content[array_rand($content)]; 
} 

function getCountryContent($country_name) { 

    // checks do we already have content for this state 
    if(!isset($country_content[$country_name])) { 

     // generate file name 
     $file_name = "country/"; 
     $file_name .= str_replace(" ", "", ucwords($country_name)); 
     $file_name .= ".txt"; 

     $country_text = file_get_contents($file_name); 
     $country_content[$country_name] = explode("\n", $country_text); 
    } 

    return $country_content[$country_name]; 
} 

function getCountryIpByName($country_name) { 
    $content = getCountryContent($country_name); 
    return $content[array_rand($content)]; 
} 

用法：

if ($result->num_rows > 0) { 
    // output data of each row 
    echo "<div class='block'><div class='rows'>"; 

    while($row = $result->fetch_assoc()) { 

     if (!empty($row["state"]) && $row["country"] == "united states") { 
      $stateip = getStateIpByName($row["state"]); 
      $a++; 
      echo $stateip; 
     } 

     else if (empty($row["state"]) && $row["country"] == "united states") { 
      $countryip = getCountryIpByName($row["country"]); 
      $a++; 
      echo $countryip; 
      } 

     else if ($row["country"] != "united states") { 

     } 

    } 

Answer 1

正如我在評論說，

這些聲明每次從while()循環中調用相應的函數時，和$country_content[$country_name] = explode("\n", $country_text);都會操作/更改原始數組。

解決方案是，（在聊天討論後）

變化getStateContent()，並以下列方式getCountryContent()功能，

function getStateContent($state_name) { 
    // checks do we already have content for this state 
    global $state_content; 
    $state_name = str_replace(" ", "", ucwords($state_name)); 
    if(in_array($state_name, $state_content)) { 
     // generate file name 
     $file_name = "state/"; 
     $file_name .= $state_name; 
     $file_name .= ".txt"; 

     $state_text = file_get_contents($file_name); 
     $ipaddresses = explode("\n", $state_text); 
     return $ipaddresses; 
    } 
} 

和

function getCountryContent($country_name) { 
    // checks do we already have content for this state 
    global $country_content; 
    $country_name = str_replace(" ", "", ucwords($country_name)); 
    if(in_array($country_name, $country_content)) { 
     // generate file name 
     $file_name = "country/"; 
     $file_name .= $country_name; 
     $file_name .= ".txt"; 

     $country_text = file_get_contents($file_name); 
     $ipaddresses = explode("\n", $country_text); 
     return $ipaddresses; 

    } 
}
