Query¶
Query is a generic term in PHP. It refers to a command, written in a specific format, and that is processed by a separate engine.
Hence, query has several usages:
SQL query, when sending command to a SQL server. This is possibly the most common usage.
The query string, a part of the URL
HTTP query, when processing or submitting command via HTTP
LDAP query, when communicating with a LDAP server
