php - Modify how Function takes and queries DB? -

the following here current function:

public function get($table, $where) {     if (count($where) === 3) {         $operators = array(             '=',             '>',             '<',             '>=',             '<='         );          $field    = $where[0];         $operator = $where[1];         $value    = $where[2];          if (in_array($operator, $operators)) {             $sql = "select * {$table} {$field} {$operator} ?";              if (!$this->query($sql, array(                 $value             ))->error()) {                 return $this;             }         }     }     return false;  } 

i modify function allow more variables in sql eg:

select * table id=2 , field2 = 'test'; 

currently takes query this:

get('table', array('field', '=', 'a')); 

i want modify take query this:

get('table', array('field1', '=', 'a' , 'field2', '=', 'b')); 

does make sense?

i still learning if there issue in code please let me know :)

thanks

<?php function _get($table, $wheres, $operatorbtwnwheres = "and") {     $conditions = array();     $operators = array('=', '>', '<', '>=', '<=' );      foreach($wheres $where) {         if (count($where) === 3) {             $field    = $where[0];             $operator = $where[1];             $value    = $where[2];              if (in_array($operator, $operators))                  $conditions[] = " $field $operator $value ";         }     }     $w = implode($operatorbtwnwheres, $conditions);     return "select * $table $w;"; }  echo _get('yourtable', array( array('field1', '=', "'a'"), array('field2', '=', "'b'") )); // output: select * yourtable field1 = 'a' , field2 = 'b' ;  echo _get(     'yourtable2',      array( array('field3', '<', "10"), array('field4', '>', "8"), array('field5', '<=', "0") ),     "or"); // output: select * yourtable2 field3 < 10 or field4 > 8 or field5 <= 0 ; ?>
