Example of dl function usage in php and dl Function

This example describes the usage of php dl functions. Share it with you for your reference. The details are as follows:

PHP dl functions are described as follows:
Http://www.php.net/manual/en/function.dl.php

The usage example is as follows:
Copy codeThe Code is as follows: <? Php
// Example loading an extension based on OS
If (! Extension_loaded ('sqlite ')){
If (strtoupper (substr (PHP_ OS, 0, 3) === 'win '){
Dl ('php _ sqlite. dll ');
} Else {
Dl ('sqlite. so ');
}
}
// Or, the PHP_SHLIB_SUFFIX constant is available as of PHP 4.3.0
If (! Extension_loaded ('sqlite ')){
$ Prefix = (PHP_SHLIB_SUFFIX = 'dll ')? 'Php _':'';
Dl ($ prefix. 'sqlite. '. PHP_SHLIB_SUFFIX );
}
?>
Dl ("memcache. so ");
In this way, as long as the php. ini file is configured, you can stop referencing the so file. Otherwise, multiple references will be said.
Copy codeCode: extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613 /"
; Extension = memcache. so

I hope this article will help you with PHP programming.
