從PHP中獲取數組數組中的數據

我得到了一個config.php，裏面有3個數據庫憑證。問題是：我沒有得到確定的DB憑據。我不知道如何訪問內部陣列陣列，而不該數組內提供信息，我不能這樣做，因爲我想這一切只有在config.php
我的config.php：從PHP中獲取數組數組中的數據

<?php 
    //Do not change identificators 
    $cfgrange = array(
     "db_range" => array(

你可以做'$ cfgrang [ 'db_range'] [ 'db_texts'] [ 'DB_NAME']'和類似的東西來訪問每個值。 –

有沒有提供這些信息的訪問方式？ –

這將無法正常工作，對此感到抱歉...如果您想使用索引訪問array_keys，請改爲 –

您可以創建一個新的數組作爲

$db_credentials = $cfgrang['db_range']['db_texts'][];

，那麼你可以很容易地通過$db_credentials ['dbname'], $db_credentials['username'];

好像** Nijraj **在輸入答案時說了同樣的話。 –

嗨，兄弟，謝謝。請檢查主帖 –

如果您要訪問您的數組作爲

$cfgrange[0][0][0];

除了

$cfgrange["db_range"]["db_texts"]["dbname"];

比你的陣列獲取的用戶名，則dbname等應聲明爲

$cfgrange = array(
"0" => array(
     "0" => array(
      "0" => "DBNAME", 
      "1" => "", 
      "2" => "", 
      "3" => "" 
     )), 
     "db_range" => array(
     "db_texts" => array(
    "dbname" => "DBNAME", 
    "username" => "", 
    "password" => "", 
    "host" => "" 
    )), 

    );

現在你可以爲你的需要訪問

echo $cfgrange["db_range"]["db_texts"]["dbname"]; 
echo "<BR>".$cfgrange[0][0][0];
