CI Framework common function Encapsulation Instance _php instance

The examples in this paper describe the common function encapsulation of CI framework. Share to everyone for your reference, as follows:

/*** Package Query functions */public function get_what ($table = ", $where =array (), $fields = ' * ') {if (' = = $table) {return false;    }//Query and return related results $query = $this->db->select ($fields)->where ($where)->get ($table);    $res = $query->result_array (); return $res;} /*** Package single query function */public function get_row ($table = ", $where =array (), $fields = ' * ') {if (' = = $table) {return false    ;    }//Query and return related results $query = $this->db->select ($fields)->where ($where)->get ($table);    $res = $query->row_array (); return $res;} /*** Package Update functions */public function update_what ($table = ", $where =array (), $data = Array ()) {if (' = = $table | | true = = = Empty ($where) | |    true = = = Empty ($data)) {return false;    }//update the corresponding field $query = $this->db->update ($table, $data, $where); return $query;} /*** Extended database function self-increment * using:* $table = ' Codeuser '; $where = array (' ID ' =>1); $data = Array (' usestate ' = ' usestate+1 ', ' Imgtype ' = ' imgtype-1 '); */public function Update_count ($table = ", $where =array (), $data =array ()) {//If the table name is empty or the data is empty, return false if (' = = $table | | empty ($DATA)) {Retu     RN false; } foreach ($data as $key = + $val) {if (False!== Stripos ($val, ' + ') | | false!== stripos ($val, '-') {$th       Is->db->set ($key, $val, FALSE);       }else{$this->db->set ($key, $val);     }} $res = $this->db->where ($where)->update ($table); return $res;}      /*** encapsulated Insert Function */public functions insert_what ($table = ', $data = Array ()) {if (' = = $table | | true = = = Empty ($data)) {    return false;    }//Insert related record $query = $this->db->insert ($table, $data); return $query;} /*** Delete Record encapsulation function */public functions delete_what ($table = ", $where =array ()) {if (true = = = Empty ($where) | |    "= = $table) {return false;    }//delete related table records $query = $this->db->delete ($table, $where); return $query;} /*** Debug Correlation function */Public Function debug_what ($org _error = ") {$con = $this->router->fetch_clasS ();    $func = $this->router->fetch_method (); if ($org _error) {$error. = Date ("Y-m-d h:i:s", Time ()). "      \ r \ n "; $error. = __file__. "      \ r \ n ";      $error. = $con. "Under controller: \ r \ n";      $error. = $func. "Method debug information is as follows: \ r \ n"; $error. = $org _error;file_put_contents ("./error_log.txt", $error. "    \ r \ n ", file_append); }}
