insert array element into database - php

I have this function : it's work correctly,
function ms_get_did_detail($id) {
global $link;
$q2="select Dest,Priority from destpr where Id='$id'";
if($res2=mssql_query($q2)) {
while($row2[]=mssql_fetch_array($res2,MSSQL_ASSOC)) {
return $row2;
}
return 0;
}
return 0;
}
I want insert every element (every Dest & Priority) into MYSQL
if($info=ms_get_did_detail($value)) {
print_r($info);
$destination = $info['Dest'];
$priority = $info['Priority'];
my_did_destination ($priority , $dest , $active , $did_voip , $cc_id);
}
It returns array like this :
[0]=> Array (
[Dest] => 100
[Priority] => 1
)
[1]=> Array (
[Dest] => 200
[Priority] => 3
)
[2] => (
)
also , I have this function to insert value in database :
function my_did_destination($priority="",$destination="") {
global $link_voip;
$sql="INSERT INTO cc_did_destination (destination,priority)
VALUES ('$destination','$priority')";
$retval = mysql_query( $sql , $link_voip);
if(! $retval ) {
die('Could not enter data: ' . mysql_error());
}
}
but It's insert empty value within

You are inserting all rows with an ID of 0, so, if a row with id=0 already exists, it will fail and will not be inserted.
Maybe the easiest solution would be to make yout ID column autoincrement with an SQL statement like:
ALTER TABLE cc_did_destination
MODIFY COLUMN id INT auto_increment;
And then change your INSERT statement for:
$sql="INSERT INTO cc_did_destination (destination,priority)
VALUES ('$destination','$priority')";

Your $info is array of rows, it has numeric keys, not 'Dest'.
You should add index, like $dest = $info[0]['Dest'].
if($info=ms_get_did_detail($value))
{
print_r($info);
$dest = $info[0]['Dest'];
$priority = $info[0]['Priority'];
my_did_destination ($priority , $dest , $active , $did_voip , $cc_id);
}
Or you can iterate through $info with a loop:
if($info=ms_get_did_detail($value))
{
foreach($info as $row) {
$dest = $row['Dest'];
$priority = $row['Priority'];
my_did_destination ($priority , $dest);
}
}
also, remove id from your insert statement

your array is:
[0]=> Array (
[Dest] => 100
[Priority] => 1
)
[1]=> Array (
[Dest] => 200
[Priority] => 3
)
[2] => (
)
so it is a multidimensional array. if you need to insert all those entries, you shouldn't run multiple queries for the same thing. just use mysql batch insert syntax. (e.g. INSERT INTO tbl (col1,col2,col3) VALUES(a,b,c),(d,e,f),(g,h,i))
build the query string for insert.
foreach($a as $i => $v)
{
$b[] = '("'.$v['Dest'].'","'.$v['Priority'].'")';
}
$c = implode(',', $b);
$sql = "INSERT INTO cc_did_destination (destination,priority)
VALUES ".$c;
then run the query
N.B.
Please, don't use mysql_* functions in new code. They are no longer maintained and are officially deprecated. See the red box? Learn about prepared statements instead, and use PDO or MySQLi - this article will help you decide which. If you choose PDO, here is a good tutorial.

There are a couple of issues here.
Firstly your first function returns an array of arrays. Ie, it returns an array with subscript 0 for the first row (it only ever returns one rows details), which is an array containing that rows details.
You assign this to the $info variable, so it contains:-
[0]=> Array (
[Dest] => 100
[Priority] => 1
)
You then assign $info['Dest'] to $destination and $info['Priority'] to $priority. However neither of these exist. You would need $info[0]['Dest'] and $info[0]['Priority'].
2nd issue is that you are trying to assign a specific value to the auto increment id field. Just leave it out of the insert, or give it a value of null.
Quick rewrite and I would suggest you need something like this:-
<?php
if($info=ms_get_did_detail($value))
{
print_r($info);
foreach($info AS $info_row)
{
$destination = $info_row['Dest'];
$priority = $info_row['Priority'];
my_did_destination ($priority , $dest , $active , $did_voip , $cc_id);
}
}
function ms_get_did_detail($id)
{
global $link;
$q2="select Dest,Priority from destpr where Id='$id'";
if($res2=mssql_query($q2))
{
if ($row2[]=mssql_fetch_array($res2,MSSQL_ASSOC))
{
while ($row2[]=mssql_fetch_array($res2,MSSQL_ASSOC))
{
}
return $row2;
}
else
{
return 0;
}
}
return 0;
}
function my_did_destination($priority="",$destination="")
{
global $link_voip;
$priority = mysql_real_escape_string($priority);
$destination = mysql_real_escape_string($destination);
$sql="INSERT INTO cc_did_destination (id,destination,priority) VALUES (NULL,'$destination','$priority')";
$retval = mysql_query( $sql , $link_voip);
if(! $retval )
{
die('Could not enter data: ' . mysql_error());
}
}
EDIT
If you want to avoid multiple inserts unnecessarily then it might be easier to use an object. This way you can do the inserts easily when there are enough batched up (I normally do 255 at a time).
Something like this, although you probably should use mysqli_*
<?php
if($info=ms_get_did_detail($value))
{
print_r($info);
$insert_object = new insert_details($link_voip);
foreach($info AS $info_row)
{
$insert_object->set_row($info_row['Priority'], $info_row['Dest']);
}
unset($insert_object);
}
function ms_get_did_detail($id)
{
global $link;
$q2="select Dest,Priority from destpr where Id='$id'";
if($res2=mssql_query($q2))
{
if ($row2[]=mssql_fetch_array($res2,MSSQL_ASSOC))
{
while ($row2[]=mssql_fetch_array($res2,MSSQL_ASSOC))
{
}
return $row2;
}
else
{
return 0;
}
}
return 0;
}
class insert_details()
{
private $db;
private $insert_row = array();
public function __CONSTRUCT($db)
{
$this->db = $db;
}
public function __DESTRUCT()
{
$this->do_insert();
}
public function set_row($priority="",$destination="")
{
$priority = mysql_real_escape_string($priority, $this->db);
$destination = mysql_real_escape_string($destination, $this->db);
$this->insert_row[] = "(NULL,'$destination','$priority')";
if (count($this->insert_row) > 255)
{
$this->do_insert();
}
}
private function do_insert()
{
$sql="INSERT INTO cc_did_destination (id,destination,priority) VALUES ".implode(',', $this->insert_row);
$retval = mysql_query($sql, $this->db);
if(! $retval )
{
die('Could not enter data: ' . mysql_error());
}
$this->insert_row = array();
}
}
Quick rough mysqli_* equivalent, assuming that $link_voip is a mysqli connection. Note that prepared statements with bound parameters are an option (and it makes it harder to forget to escape variables), but it can become a bit messy when you are doing multiple inserts like this.
<?php
if($info=ms_get_did_detail($value))
{
print_r($info);
$insert_object = new insert_details($link_voip);
foreach($info AS $info_row)
{
$insert_object->set_row($info_row['Priority'], $info_row['Dest']);
}
unset($insert_object);
}
function ms_get_did_detail($id)
{
global $link;
$q2="select Dest,Priority from destpr where Id='$id'";
if($res2=mssql_query($q2))
{
if ($row2[]=mssql_fetch_array($res2, MSSQL_ASSOC))
{
while ($row2[]=mssql_fetch_array($res2, MSSQL_ASSOC))
{
}
return $row2;
}
else
{
return 0;
}
}
return 0;
}
class insert_details()
{
private $db;
private $insert_row = array();
public function __CONSTRUCT($db)
{
$this->db = $db;
}
public function __DESTRUCT()
{
$this->do_insert();
}
public function set_row($priority="",$destination="")
{
$priority = mysqli_real_escape_string($this->db, $priority);
$destination = mysqli_real_escape_string($this->db, $destination);
$this->insert_row[] = "(NULL,'$destination','$priority')";
if (count($this->insert_row) > 255)
{
$this->do_insert();
}
}
private function do_insert()
{
$sql="INSERT INTO cc_did_destination (id,destination,priority) VALUES ".implode(',', $this->insert_row);
$retval = mysqli_query($this->db, $sql);
if(! $retval )
{
die('Could not enter data: ' . mysqli_sqlstate($this->db));
}
$this->insert_row = array();
}
}

PHP Improve performance to execute multiple queries while reading a file with thousand lines

I'm trying to build a script where I need to read a txt file and execute some process with the lines on the file. For example, I need to check if the ID exists, if the information has updated, if yes, then update the current table, if no, then insert a new row on another temporary table to be manually checked later.
These files may contain more than 20,30 thousand lines.
When I just read the file and print some dummie content from the lines, it takes up to 40-50ms. However, when I need to connect to the database to do all those verifications, it stops before the end due to the timeout.
This is what I'm doing so far:
$handle = fopen($path, "r") or die("Couldn't get handle");
if ($handle) {
while (!feof($handle)) {
$buffer = fgets($handle, 4096);
$segment = explode('|', $buffer);
if ( strlen($segment[0]) > 6 ) {
$param = [':code' => intval($segment[0])];
$codeObj = Sql::exec("SELECT value FROM product WHERE code = :code", $param);
if ( !$codeObj ) {
$param = [
':code' => $segment[0],
':name' => $segment[1],
':value' => $segment[2],
];
Sql::exec("INSERT INTO product_tmp (code, name, value) VALUES (:code, :name, :value)", $param);
} else {
if ( $codeObj->value !== $segment[2] ) {
$param = [
':code' => $segment[0],
':value' => $segment[2],
];
Sql::exec("UPDATE product SET value = :value WHERE code = :code", $param);
}
}
}
}
fclose($handle);
}
And this is my Sql Class to connect with PDO and execute the query:
public static function exec($sql, $param = null) {
try {
$conn = new PDO('mysql:charset=utf8mb4;host= '....'); // I've just deleted the information to connect to the database (password, user, etc.)
$q = $conn->prepare($sql);
if ( isset($param) ) {
foreach ($param as $key => $value) {
$$key = $value;
$q->bindParam($key, $$key);
}
}
$q->execute();
$response = $q->fetchAll();
if ( count($response) ) return $response;
return false;
} catch(PDOException $e) {
return 'ERROR: ' . $e->getMessage();
}
}
As you can see, each query I do through Sql::exec(), is openning a new connection. I don't know if this may be the cause of such a delay on the process, because when I don't do any Sql query, the script run within ms.
Or what other part of the code may be causing this problem?
First of all, make your function like this,
to avoid multiple connects and also o get rid of useless code.
public static function getPDO() {
if (!static::$conn) {
static::$conn = new PDO('mysql:charset=utf8mb4;host= ....');
}
return static::$conn;
}
public static function exec($sql, $param = null) {
$q = static::getPDO()->prepare($sql);
$q->execute($param);
return $q;
}
then create unique index for the code field
then use a single INSERT ... ON DUPLICATE KEY UPDATE query instead of your thrree queries
you may also want to wrap your inserts in a transaction, it may speed up the inserts up to 70 times.

mysqli_multi_query database class error

I am sure of this that this question hasn't asked anywhere even on the blog of creator of this class.
since morning i have started using php database class of bennettstone. I was trying to add MYSQLI_MULTI_QUERY into this class to handle multiple queries at once.
till now, I have been able to modify up to below extent. But it is not working. I am extremely poor with classes & this is my first attempt ever !!
I am getting error at two lines & don't know how i will access the result set of multiple queries. let's say 3 queries.
1) Error at while statement And similar error at mysqli_free_result statement
Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given on line 352
Request some help:
public function multi_select_query( $query )
{
$i = 0;
$row = array();
$query = $this->link->multi_query( $query );
if ( mysqli_error( $this->link ) ) {
$this->log_db_errors( mysqli_error( $this->link ), $query, 'Fatal' );
return false;
} else {
do {
$i ++;
$result[$i] = mysqli_store_result($this->link);
while ( $r = mysqli_fetch_array( $query, MYSQLI_ASSOC )) {
$row[$i][] = $r;
}
mysqli_free_result( $query );
} while ( $this->link->more_results() && $this->link->next_result() );
return $row[$i];
}
}
Finally, I made it myself somehow.
Below is the final working class example which can be easily accessed by foreach loop using following statement.
$result = $dbc->multi_select_query($query);
public function multi_select_query( $query )
{
$row = array();
$i = 0;
$query = $this->link->multi_query( $query );
if( mysqli_error( $this->link ) ){
$this->log_db_errors( mysqli_error( $this->link ), $query, 'Fatal' );
return false;
} else {
do{
$i ++;
if($result[$i] = $this->link->store_result())
{
while ($r[$i] = $result[$i]->fetch_row())
{
$row[$i][] = $r[$i];
}
$result[$i]->free();
}
} while( $this->link->more_results() && $this->link->next_result() );
return $row;
}
}

How to Update Table based on Array Keys as column names? PDO

This is different from Insert based on Keys
I would like to know how to use the array_keys of an array as column names for an update query. The object is that I have a form with all the data a user can update like Gender, Country, Nationality, etc. But say the user only wants to update their Country, therefor array_filter filters the array of all NULL/Empty values. Then I want the keys as names of Columns to update; however, I'd like to know how to bind them together.
Perhaps so they go together like so:
"UPDATE Users SET" . $Columns . "WHERE ID = 5";
I want Columns to be in the format. "Nation = US, Gender = Male" etc.
My current code:
<?php
class Update {
private $UpdateColumn;
private $UpdatedData;
private $ID;
protected $Connect;
protected $Data;
public function __construct($UpdateColumn, $ID) {
try {
$this->Connect = new pdo(****); //Hidden for privacy test server
$this->Connect->setAttribute(
PDO::ATTR_ERRMODE,
PDO::ERRMODE_EXCEPTION
);
} catch(PDOException $ex) {
die(json_encode([
'outcome' => false,
'message' => 'Unable to connect'
]));
}
$this->UpdateColumn = $UpdateColumn;
$this->ID = $ID;
}
public function bindData() {
$this->Data = [
$this->UpdateColumn,
$this->ID
];
return $this->Data;
}
public function checkForErrors(){
foreach($this->Data as $Data){
$Error = false;
if(empty($Data)){
$Error = true;
}
if(isNum($Data[1])){
$Error = true;
}
}
return $Error;
}
public function Update() {
$Query = $this->Connect->prepare(
"UPDATE Users SET". $this->Data[0] . "WHERE ID = :ID"
);
$Query->bindValue(":ID", $this->Data[1]);
$Query->execute();
}
public function Redirect(){
return header("Location: /Profile?ID=$this->Data[1]");
}
}
Place to use the code.
<?php
session_start();
require_once("Scripts/PHP/Class/Update.class.php");
$DataUpdate = array_filter($_POST);
$Columns = array_keys($DataUpdate);
$ColumnsToUpdate = implode($Columns, ", ");
//I want to have ColumnsToUpdate look like: Gender = Male, Age = 67, format
//$Update = new Update($ColumnsToUpdate, $DataUpdate, $_SESSION['ID']);
?>
In my case then, I will need an array delimiter which I could use to go through each array_key with it's counterpart data
$Array = array(
"Age" => 9,
"Gender" => "Boy",
"Country" => "",
);
$Array = array_filter($Array);
$Columns = array_keys($Array);
$ColumnToSend = "";
foreach($Array as $Arr => $Key){
$ColumnToSend .= $Arr ."=". $Key . ",";
}
echo($ColumnToSend);
That produces the desired format, but would it work if it was put into a query?

get data from array in cakephp

I'm trying to get the data from array in my controller php on Cakephp.
I have this function:
public function updateUserStatus() {
if(isset($this->params['url']["pcs"])) {
$uus = array( "pcs" =>$this->params['url']["pcs"] );
$trans = $this->Transaction->updateUserStatus($uus);
} else {
$trans = "failed";
}
$this->set('trans', $trans);
$this->layout = 'ajax';
}
And I want to get the data from status_id who have this response:
Array (
[0] => Array
(
[status_id] => 2
)
[1] => Array
(
[rem_time] => 66
)
)
How can I do it?
My question is how can i get the data for status_id ?
public function updateUserStatus() {
if (isset($this->params['url']["pcs"])) {
$uus = array("pcs" =>$this->params['url']["pcs"]);
$trans = $this->Transaction->updateUserStatus($uus);
} else {
$trans = "failed";
}
$currentStatus = 0;
if (is_array($trans) && isset($trans['status_id'])) {
$currentStatus = $trans['status_id'];
}
$this->set('trans', $trans);
$this->layout = 'ajax';
}
public function updateUserStatus($uus){
if(isset($uus["pcs"])) {
$sql = "SELECT status_id as status_id , rem_time as rem_time FROM phones WHERE pcs = '".$uus["pcs"]."' LIMIT 1";
$query = $this->query($sql);
return $query[0]['phones'];
} else {
return "failed";
}
}
Notice, we are returning $query[0]['phones'].
Let me know if it works.
The code could also use some refactoring.
For example, why is the function called updateUserStatus if it is only returning the result of a query? It should also always return an array, for consistency.

function returning only once, why?

During my coding I really got stuck into this problem.
I ran a foreach loop and for every item I had to get a certain value from a function.
But I got only one returned. I could not figure out what was happening. I hope you guys surely will.
Below is the short version of my program.
Database structure is given at last.
<?php
function opendb() {
mysql_connect("localhost", "root", "root");
mysql_select_db("something_db");
}
function sql_query($sql) {
$datas = array();
if ($res = mysql_query($sql)) {
$x = 0;
while ( $data = mysql_fetch_assoc($res) ) {
$datas[$x] = $data;
$x += 1;
}
}
return $datas;
}
function get_parent_id($table, $parent, $cid) {
// cid=>child id
$sql = "SELECT * FROM $table WHERE id=$cid";
$datas = sql_query($sql);
$pid = $datas[0]['parent'];
$p_id = $datas[0]['id'];
if ($pid != 0) {
get_parent_id($table, $parent, $pid);
} else {
return $p_id;
}
}
opendb();
$datas_pkg = sql_query("SELECT * FROM tbl_packages WHERE 1");
foreach ( $datas_pkg as $data_pkg ) {
echo $data_pkg['destination_id'] . '-->';
echo $parent_id = get_parent_id('tbl_destinations', 'parent', $data_pkg['destination_id']);
echo '<br/>';
}
?>
Database structure..
tbl_destinations
+--------+-------------------------+-----------+
| id(int)|destination_name(Varchar)|parent(int)|
+--------+-------------------------+-----------+
tbl_packages
+-------+---------------------+-------------------+
|id(int)|package_name(varchar)|destination_id(int)|
+-------+---------------------+-------------------+
If I did not clear my question please let me know so that I can help you to help me.
if($pid!=0)
{
get_parent_id($table,$parent,$pid);
}
You call the function, but never use its value.
