Transfer from http://blog.itpub.net/22664653/viewspace-1692317/An introductionI believe many development/dba in the process of using MySQL, the way that MySQL handles multi-table association or performance has been not satisfied. For the development of a submitted query with joins, it is generally more resistant, which suggests splitting the join to avoid possible performance problems associated with the join, as well as increasing the network interaction between the program and the DB.Prior to

In PHP, the Foreach Loop statement, commonly used to iterate over an array, is generally used in two ways: Do not remove the label, remove the label.(1) value only, do not remove the label(2) Remove the mark and value at the same timeTaskList all student names!There is a set of arrays with the name of the number as subscript, and the name of the array needs to be traversed.1.
