PHP MongoDB context options

PHPServer Side ProgrammingProgramming

Introduction

PHP can interact with MongoDB database through database extensions. For older versions of PHP, mongo driver can be installed from PECL. This has now been replaced by mongodb driver. Both drivers can be installed using precompiled binaries for Linux/Windows/MacOS operating systems. Alternately, manual installation can be done from source tarball available on github. In either case, mongo or mongodb extension should be enabled in php.ini settings.

The PHP MongoDB extension provides Stream Context Support using the mongodb context. Relevent context options are as follows
