php connection postgreSql

S Environment: wampserver64 pHP5.5.12

1. Remove the comma before the extension = php_pdo_pdo_pgsql.dll and extension = php_pgsql.dll; .dll
(libpq.dll under the php folder) and

./php/ext/php_pgsql.dll(php_pgsql.dll under the ext folder)php_pdo_pgsql.dllThese 3 dlls Copy the file to the C drive system32 3.Normally, php can connect to postgres, but I still get an error, prompting "Fatal error: Call to undefined function pg_connect()", check Apache's log, "PHP Startup: Unable to load dynamic library '****\PHP5\ext\php_pdo_pgsql.dll".

After searching, conf in Apache Add LoadFile "***/PHP5/libpq.dll" to the configuration file httpd.conf under the folder, and the location is after LoadModule (*** is the php installation path) 4. Test code

<?php
$conn_string  =  "host=localhost port=5432 dbname=db_name user=your user password=your password" ; 
$dbconn = pg_connect($conn_string);
if (!$dbconn) 
    echo "连接失败！！！！！/r/n";
else 
    echo "连接成功！！！！！/r/n";
    pg_close($dbconn);
?>
