i have tried the following code to insert the relevant datas into database

<?php
$connect= mysqli_connect("localhost","root","","result");
$jsondata=file_get_contents("result.json");
$json= json_decode($jsondata,true);
$results=$json['results'];
$n= sizeof($results);
for($i=0;$i<$n;$i++){

$row=$results[$i];
foreach($row['tickets'] as $key => $value){


$sql="INSERT into
event(name,url,imageUrl,dateCreated,eventName,addressLine1,addressLine2,ticketNa me,price)
VALUES('".$row["name"]."','".$row["url"]."','".$row["imageUrl"]."','".$row["dateCreated"]."','".$row["venue"]["name"]."','".$row["venue"]["addressLine1"]."','".$row["venue"]["addressLine2"]."','".$value["name"]."','".$value["price"]."')";

mysqli_query($connect,$sql);
}
}

echo "events data inserted";
?>


This enters the respective datas into my database but because of the nested array tickets with respective keys name and price the same events are being posted twice into my database like MOVIES AT THE PARK @ GIBA GORGE for price 100 is one one row and MOVIES AT THE PARK @ GIBA GORGE for price 80 on another row ... I have to display these datas in future as part of one event name with their the ticket type and price as a table... do you have any idea on any other way i can make it better, instead of having two rows for same events?

tickets

name

price

MOVIES AT THE PARK @ GIBA GORGE

100

MOVIES AT THE PARK @ GIBA GORGE

80

Thanks in advance

for those who have been suggesting me not to use for and foreach loop this is my update code after removing for loop and a single foreach loop and it gives me an error of undefined index of name and price under tickets

<?php
$connect= mysqli_connect("localhost","root","","result");
$jsondata=file_get_contents("result.json");
$json= json_decode($jsondata,true);
$results=$json['results'];

foreach($results as $key => $result){

$sql="INSERT into `event(name,url,imageUrl,dateCreated,eventName,addressLine1,addressLine2,ticketName,price) VALUES('".$result["name"]."','".$result["url"]."','".$result["imageUrl"]."','".$result["dateCreated"]."','".$result["venue"]["name"]."','".$result["venue"]["addressLine1"]."','".$result["venue"]["addressLine2"]."','".$result["tickets"]["name"]."','".$result["tickets"]["price"]."')";`
mysqli_query($connect,$sql);
}

echo "events data inserted";
?>


hence i have further updated my code by using two foreach loops, one to ietrate through the top level array "results" and the other to iterate through the nested array "tickets"

<?php
$connect= mysqli_connect("localhost","root","","result");
$jsondata=file_get_contents("result.json");
$json= json_decode($jsondata,true);
$results=$json['results'];

foreach($results as $key => $result){
foreach($result["tickets"] as $k => $v){
$sql="INSERT into event(name,url,imageUrl,dateCreated,eventName,addressLine1,addressLine2,ticketName,price) VALUES('".$result["name"]."','".$result["url"]."','".$result["imageUrl"]."','".$result["dateCreated"]."','".$result["venue"]["name"]."','".$result["venue"]["addressLine1"]."','".$result["venue"]["addressLine2"]."','".$v["name"]."','".$v["price"]."')";`
mysqli_query($connect,$sql);
}
}

echo "events data inserted";
?>


that iterates through the nested array so there is nothing wrong in my code now the only problem is i am getting 2 events on my table because of two ticket types adult and children in "tickets" array

so as per many suggestions here i need to create two separate tables for events and tickets i would appreciate if anyone can tell me that how do iconnect these two tables to be able to show the information of my events in html with ticket type and price shown in html table tag thanks in advance

The main reason that is happening is look at the below code :

$row=$results[$i];
foreach($row['tickets'] as $key => $value){

$sql="INSERT into event(name,url,imageUrl,dateCreated,eventName,addressLine1,addressLine2,ticketNa me,price) VALUES('".$row["name"]."','".$row["url"]."','".$row["imageUrl"]."','".$row["dateCreated]."','".$row["venue"]["name"]."','".$row["venue"]["addressLine1"]."','".$row["venue"]["addressLine2"]."','".$value["name"]."','".$value["price"]."')";

mysqli_query($connect,$sql);
}


The $row contains your one main entry and $row['tickets'] contains 2 entries and you are using the $row main contents inside the loop for tickets. That is the reason you are getting 2 entries. The best way to cope this is to use a single foreach loop instead of using a for and a foreach.

$row

$row['tickets']

EDIT:

Actually I would like to suggest to normalize your table by breaking this into 2 tables, one for storing event information and the other for using the ticket information. See the structure below:

event(id,name,url,imageUrl,addressLine1,addressLine2,dateCreated);
event_tickets(id,event_id,ticketName,price,dateCreated);


This will help you maintain the information easily. Also you can modify the code to something like this :

$sql="INSERT into event(name,url,imageUrl,addressLine1,addressLine,2dateCreated) VALUES ('".$row['name']."','".$row['url']."','".$row['imageUrl']."','".$row['venue']['addressLine1']."','".$row['venue']['addressLine2']."','".date('Y-m-d h:i:s')."');"
mysqli_query($connect, $sql);
$event_id = mysqli_insert_id($connect);


And then you can use a foreach to insert the ticket information in the event_tickets table.

Hope this helps

it's because you're using a foreach within a for. You just want a foreach:

foreach ($multiArray as $key => $singleArray) {
//rest of code, replacing $row with $singleArray['key']. E.g. $singleArray['id']
}


update after seeing OP update:

so you would do:

foreach ($results as $row) {
foreach ($row['tickets'] as $ticket) {
//sql
}
}


this should allow you to use $ticket['key'] in your SQL - though I do suggest switch to PDO prepared statements to protect yourself from SQL injection.

$ticket['key']

Also as other suggested, separating tickets into its own table would be highly advantageous to you.

$singleArray['tickets']

2 x count(tickets)

results

tickets

$results as $key => $result

$result['tickets']
