: This article mainly introduces PHP multi-dimensional array sorting. For more information about PHP tutorials, see. Call the user-defined sorting function of usort (). it must receive two parameters. The first parameter is the array to be sorted, and the second parameter is a callback function. if the sorting is successful, true is returned, false is returned when a failure occurs.
The callback function receives two parameters. if false or negative is returned, the first parameter is placed before the second parameter. if true or positive is returned, the first parameter is placed behind the second parameter.
The code is as follows:
'). AddClass ('pre-numbering '). hide (); $ (this ). addClass ('Has-numbering '). parent (). append ($ numbering); for (I = 1; I <= lines; I ++) {$ numbering. append ($ ('
'). Text (I) ;}; $ numbering. fadeIn (1700) ;}) ;}; script
