Some tips for PHP and apache configuration
1. extension_dir = string
Scope: PHP_INI_SYSTEM Default: ./ (on windows, defaults to ext) Tells PHP the location of loadable extension modules.2. extension = php_mysqli.dll and extension = php_mysql.dll
The reason why two extension libraries are activated for php during configuration is because: In order to use basic function operations to access mysql databaseserver, mysql must be added when configuring php support, that is, using the php_mysql.dll extension library.
Although the php_mysql.dll extension library is compatible with mysql 4.1.0 and later machine versions, it does not support the additional functions provided by these versions. To use these functions, you also need to use the php_mysqli.dll extension library.
3.php_mbstring.dllThe full name of the mbstring library is Multi-Byte String. That is, each language has its own encoding, and their number of bytes is different. Currently, the internal encoding of PHP only supports ISO-8859- *, EUC-JP, UTF-8
Other encoding languages cannot be displayed correctly on the PHP program.
The solution is to use the mbstring function library of php to solve it.
4.exif is an extension for reading photo information. Move extension=php_mbstring.dll in the php.ini file before extension=php_exif.dll. The reason is that exif needs to call mbstring, so mbstring must be in front. php_exif.dll, EXIF function library, requires php_mbstring.dll. And in php.ini, php_exif.dll must be loaded after php_mbstring.dll.
5.
Also note that true color functions cannot be used in GD1, use php_gd2.dll instead. |
The above introduces some tips for PHP and apache configuration, including include and sql database. I hope it will be helpful to friends who are interested in PHP tutorials.
