PHP Transformation from integer to decimal

Question

I try save integer with value 0 in php to decimal(7,2) in miranda db.

But integer with value 0 save always 99999.99 I cannot find the solution. I think it can transform automatically. I use PDO in php.

Other values than 0 works well.

My inserted array:

array(":name"=>"3ld",":urlid"=>($url->id),":date"=>"NOW()",":type"=>"renew",":status"=>($url->alias.$url->custom.".".$url->tld),":price"=>$price)

Var dump value from array:

array(6) { [":name"]=> string(3) "3ld" [":urlid"]=> string(1) "1" [":date"]=> string(5) "NOW()" [":type"]=> string(5) "renew" [":status"]=> string(19) "support.url.tld" [":price"]=> int(0) }

The part of code:

$this->db->insert("log_url",array(":name"=>"3ld",":urlid"=>($url->id),":date"=>"NOW()",":type"=>"renew",":status"=>($url->alias.$url->custom.".".$url->tld),":price"=>$price));

DB insert function:

    public function insert($table,$parameters=array()){
    $param="";
    $val="";
    $insert= $this->ph($parameters);
    //Build Query
    $query="INSERT INTO {$this->dbinfo["prefix"]}$table";                       
    if(is_array($insert)){
        $count=count($insert);
        $i=0;           
        foreach ($insert as $key => $value) {
            if($parameters[$value]=="NOW()"){
                $val.= "NOW()";
                unset($parameters[$value]);
            }else{
                $val.=$this->quote($value,$parameters);
            }                   
            $param.="`$key`";
            if(++$i != $count) {
                $param.=",";
                $val.=",";
            }               
        }
        $query.=" ($param) VALUES ($val)";
    }       
    $result = $this->db->prepare($query);
    $result->execute($parameters);
    if($this->error_message($result->errorInfo())) {
        $this->query=strtr($query,$parameters);
        $this->db_error=$this->error_message($result->errorInfo());
        exit;
    }
    ++$this->num_queries;
return TRUE;        
}

Quote function:

private function quote($string,$param=''){  
    if(empty($param)){
        return "'$string'";
    }
    return $string;
}

Generate placeholders function:

private  function ph(array $a){
    $b=array();
    foreach ($a as $key => $value) {
        $b[str_replace(":", "", $key)]="$key";
    }
    return $b;
}

Any information helps, thank you.

Updated Code:

public function insert($table,$parameters=array()){
    $param="";
    $val=array();
    $insert= array_keys($parameters); var_dump($parameters);
    //Build Query
    $query="INSERT INTO {$this->dbinfo["prefix"]}$table";

    if(is_array($insert)){

        $query.=' (`'.implode($insert,"`,`").'`) VALUES (:'.implode($insert,', :').')';

        $result = $this->db->prepare($query);

        foreach($parameters as $key=>$param) {
          $result->bindParam(":".$key, ($param['value']=='NOW()')?date('Y-m-d H:i:s'):$param['value'], PDO::PARAM_STR);
        }
    }      

    $result->execute(); //$result->execute($parameters);
    if($this->error_message($result->errorInfo())) {
        $this->query=strtr($query,$parameters);
        $this->db_error=$this->error_message($result->errorInfo());
        exit;
    }
    ++$this->num_queries;
return TRUE;        
}

produce as price 2015.00

that is not fragment of code, it i snot even one line of code :-) could you please show the fragment that shows your logic and data manipulation? 2-3-5-10 lines?? — Alex

Not sure what's the question, did you try to cast that variable? — Mark

I update the code. There is one function to insert in DB. The variable for price is integer number, but when is it zero problem is there. Other values works well. — Maximi

Replace call to method by removing ":" it has no sense to send ":" and then remove that ":" by ->ph()

$this->db->insert("log_url",
    array("name"=>array("value"=>"3ld","type"=>PDO::PARAM_STR), //
      "urlid"=>array("value"=>$url->id,"type"=>PDO::PARAM_STR),
      "date"=>array("value"=>'NOW()',"type"=>PDO::PARAM_STR),     
"type"=>array("value"=>'renew',"type"=>PDO::PARAM_STR),
"status"=>array("value"=>$url->alias.$url->custom.".".$url->tld,"type"=>PDO::PARAM_STR),
"price"=>array("value"=>$price,"type"=>PDO::PARAM_STR)));       //

about PDO types params read here: http://php.net/manual/en/pdo.constants.php and here http://php.net/manual/en/pdostatement.bindparam.php

and inside your function you can replace this:

$param="";
    $val="";
    $insert= $this->ph($parameters);
    //Build Query
    $query="INSERT INTO {$this->dbinfo["prefix"]}$table";                       
    if(is_array($insert)){
        $count=count($insert);
        $i=0;           
        foreach ($insert as $key => $value) {
            if($parameters[$value]=="NOW()"){
                $val.= "NOW()";
                unset($parameters[$value]);
            }else{
                $val.=$this->quote($value,$parameters);
            }                   
            $param.="`$key`";
            if(++$i != $count) {
                $param.=",";
                $val.=",";
            }               
        }
        $query.=" ($param) VALUES ($val)";
    }       
    $result = $this->db->prepare($query);

with this:

$val=array();
$insert= array_keys($parameters);
//Build Query
$query="INSERT INTO {$this->dbinfo["prefix"]}$table";                       
if(is_array($insert)){

    $query.=' (`'.implode($insert,"`,`").'`) VALUES (:'.implode($insert,', :').')';

    $stmt= $this->db->prepare($query);

    foreach($parameters as $key=>$param) {
      //$stmt->bindParam(":".$key, ($param['value']=='NOW()')?date('Y-m-d H:i:s'):$param['value']);
      if($param['value']=='NOW()') {
         $now = date('Y-m-d H:i:s');
         $stmt->bindParam(":".$key, $now, $param['type']); 
      } else {
         $stmt->bindParam(":".$key, $param['value'], $param['type']); 
      }
    }
}

so, this must work

by the way, don't forget change:

 $result->execute($parameters);

to

 $stmt->execute();
