The pagination effects of numbers and text in PHP self-training projects are implemented in functions

: This article describes how to implement pagination of numbers and text in PHP self-training projects in functions. For more information about PHP tutorials, see.

/***** @ Param $ _ SQL * @ param $ _ size */function _ page ($ _ SQL, $ _ size) {// obtain all the variables in the table. externally, you can access global $ _ page, $ _ pagesize, $ _ pagenum, $ _ pageabsolute, $ _ num; if (isset ($ _ GET ['Page']) {$ _ page = $ _ GET ['Page']; if (empty ($ _ page) | $ _ page <0 |!

$ _ Page-1). '"> Previous page |
';} If ($ _ page ==$ _ pageabsolute) {echo'
  
  
Next Page |
'; Echo'
  
  
Last page
';} Else {echo'
  
  
$ _ Page + 1). '"> Next page |
'; Echo'
  
  
$ _ Pageabsolute. '"> Last Page
';} Echo'
 
 
'; Echo'
';}}

Wrap the above code glob. funic. php in the core function library

Then, you only need to call the following functions in the file:

// _ Pageing function call page, 1 | 2, 1 indicates the number page, 2 indicates the text page
_ Paging (2 );
?>

The above introduces the implementation of the pagination effects of numbers and text in PHP self-training projects in functions, including some content, and hope to help friends who are interested in PHP tutorials.
