A PHP compiler is a special type of program that converts PHP statements into a machine-level language that the system’s processor can understand. The processor of any system only understands binary code, which means that the compiler translates high-level language into binary code that the processor can understand and interpret. Without a compiler, any program is useless. A compiler, which compiles a program written in it to a machine-level language, is included in all IDEs that create a comprehensive platform for editing and running a program. In fact, a compiler is nothing more than software that helps transform anything written using statements.
The WHERE clause in the PHP compiler can be used to include numerous conditions in one or more comma-separated tables. However, it is an optional part of a SELECT statement.
- You can retrieve one or more fields in a single SELECT statement;
- You can replace fields with an asterisk (*). SELECT will return all fields in this script;
- The WHERE clause allows you to specify any criteria;
- You can use OFFSET to set a starting point for the SELECT from which to return records. By default, the offset is set to zero;
- The LIMIT attribute can be used to limit the number of results.
