無法連接使用PHP

Question

我連接亞馬遜RDS使用PHP使Web服務亞馬遜我的SQL RDS，但它不連接到這裏的服務器是我的代碼

<?php 

try{ 
$dbhost = 'myrds.cjahuqpumuov.us-east-1.rds.amazonaws.com:3306'; 
$username = 'myname'; 
$password = 'mypassword'; 
$dbname = 'mydb'; 

$link = mysql_connect($dbhost, $username, $password, $dbname); 
mysql_select_db($dbname); 

} 

catch(Exception e){ 

echo e 

} 
?> 

解析錯誤：語法錯誤，意外T_STRING，預計在T_VARIABLE上/home/content/i/h/u/ihus235/html/cs/pah_brd_v1/productivo/selectTest.php線路17

Answer 1

我覺得主機名w^ith端口號是不允許你連接..嘗試通過刪除端口號如：

$dbhost = 'myrds.cjahuqpumuov.us-east-1.rds.amazonaws.com'; 

我也面臨同樣的問題前幾天。

Answer 2

<?php 

try{ 
$dbhost = 'myrds.cjahuqpumuov.us-east-1.rds.amazonaws.com'; 
$username = 'myname'; 
$password = 'mypassword'; 
$dbname = 'mydb'; 

$link = mysql_connect($dbhost, $username, $password, $dbname, 3306); 
mysql_select_db($dbname);  
} 
catch(Exception $e){  
echo 'Caught exception: ', $e->getMessage(), "\n";  
} 
?> 

Answer 3

dbhost = "hostname:port"; //default is 3306  
$link = mysql_connect($dbhost, $username, $password); 

您需要通過端口號與主機名。

Answer 4

我有類似的問題。語法錯誤，意想不到的T_STRING，在/ home /內容期待T_VARIABLE： 對我來說，這個問題是通過改變SELinux的標誌

我希望這是對你來說太
