How to insert array in single field - php

Question

I want to store ids in database like this 1,2,3,4,5 in one field from a while loop.
how can i do this.
I am trying this way.
$array = array();
while($row=mysqli_fetch_assoc($result)){
$array[] = array($row['id']);
}
$query = mysqli_query($connection,"INSERT INTO temp (temp) VALUES('$array')");
print_r($array);
This is showing error Array to string conversion and value as Array is inserted in database.
Please see and suggest any possible way to do this.
Thanks.

Answer 1

Create another table and insert 5 rows into it.
entity_id | ids
1 1
1 2
1 3
1 4
1 5
that's the only proper way of doing such things
However, if it's really a temp table, there is probably a way to avoid these inserts at all.

Answer 2

You can use either serialize or json_encode:
$data = serialize($array);
// ...or...
$data = json_encode($array);
If the array just contains plain numbers you can also use implode:
$data = implode(',', $array);

Answer 3

$arrays = array();
while($row=mysqli_fetch_assoc($result)){
$arrays[] = $row['id'];
}
$arr_str = implode(",", $arrays);
$query = mysqli_query($connection,"INSERT INTO temp (temp) VALUES('$arr_str')");
//print_r($array);
Detailed information about implode can be found here.

Answer 4

Use the implode() function:
$to_insert = implode(',', $array);
$query = mysqli_query($connection,"INSERT INTO temp (temp) VALUES('$to_insert')");

Answer 5

$query = mysqli_query($connection,"INSERT INTO temp (temp) VALUES(".join(',', $array).")");

Answer 6

Try:
$ids = join(',',$array);
$query = mysqli_query($connection,"INSERT INTO temp (temp) VALUES('$ids')");

Answer 7

Please use implode function before insert into database :-
Here is a example :-
$array = array(1,2,3);
$comma_separated = implode(",", $array);
echo $comma_separated;
Output :-
1,2,3
In your case :-
$array = array();
while($row=mysqli_fetch_assoc($result)){
$array[] = array($row['id']);
}
$comma_separated = implode(",", $array);
$query = mysqli_query($connection,"INSERT INTO temp (temp) VALUES('$comma_separated')");
print_r($array);

Answer 8

Set the field type varchar(255) and do this with php
$array = array();
$value = serialize($array);
$query = mysqli_query($connection,"INSERT INTO temp (temp) VALUES('$value')");
print_r($array);
To retrieve the value you should unserialize the column
$data = unserialize($result['temp']);
Here result is associative array. $data is an array you dont have to implode or explode or json_encode or json_decode
