一直在找一直方法，不去改php.ini 的配置，而是通过动态修改才是来配置，来支持sqlite3.
但是还是不行，因为配置完需要重启。下面为收集的相关比较：
I do not have access to /etc/php.ini and cannot uncomment the lines required to activate php extensions I require.
extensions can only be disabled by editing php.ini
or use dl() function,such as
***
if (!extension_loaded('php_pdo')) {
if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
dl('php_pdo.dll');
} else {
dl('php_pdo.so');
}
}
***
but :
Warning: dl() [function.dl]: Not supported in multithreaded Web servers - use extension=php_sqlite.dll
Only if the extension has an attribute for that.
Like:
extension.bla_enabled = 0/1 in php.ini
Then you can set it in runtime by:
ini_set("extension.bla_enabled", "0");
ini_set to update settings of php.ini file
We can't change all the configured settings of php.ini file. PHP will permit to change some data by using ini_set function. We will verify after changing the configured data by using ini_get function. Here is the code. Please note the outputs shown here will change based on your server settings when you try.
echo ini_get('mysql.connect_timeout'); // OUTPUT 60
ini_set('mysql.connect_timeout',100);
echo "<br>";
echo ini_get('mysql.connect_timeout'); // output 100
