How to dump PHP object into an SQL Table? - php

Question

I'm wondering if there is a quick way to do the following:
I have a PHP object with multiple attributes. For example
$person;
$person->height = 165;
$person->name = 'john';
I would like to dump this into an SQLite MySQL DB while creating each column automatically from the attribute names of the PHP object. So for example, if I were to dump the above object into mySQL, it would look something like this:
Table : people
Name(Column, VARCHAR) - "John"
Height(Column, INT) - 165
The reason I am asking this is because the number of attributes is growing constantly, and having to create and manage the table columns manually is a lot of work. I am wondering if there is an automated way of doing this.

First you need to convert object into array and then you can iterate through it and can create table and insert values in it.
Something like below:
Step 1: Convert object to array
Step 2: Get keys(fields) and values out of array
Step 3: Generate sql queries
<?php
//Step 1: convert object to array
//$persion = (array) $yourObject;
//Step 2: get keys(fields) and values out of array
$person = array(
"height" => "165",
"name" => "john",
"age" => "23"
);
function data_type($val) {
if(is_numeric($val)) {
return "int";
}
else {
return "varchar(15)";
}
}
//Step 3: sql query, only including sql query
function create_table($person) {
$create = "CREATE TABLE IF NOT EXISTS people";
$ctr = 0;
foreach($person as $key => $value) {
if($ctr == 0) {
$field_query = $key." ".data_type($value);
} else {
$field_query .= ", ".$key." ".data_type($value);
}
$ctr++;
}
echo $create .= " (".$field_query.")";
echo "<br/>";
}
create_table($person);
function insert_table($person) {
$ctr = 0;
foreach($person as $key => $value) {
if($ctr == 0) {
$field_query = $key;
$value_query = $value;
} else {
$field_query .= ", ".$key;
$value_query .= ", ".$value;
}
$ctr++;
}
echo $insert = "INSERT INTO people"." (".$field_query.") VALUES (".$value_query.")";
}
insert_table($person);
?>
Hope this will help you in some way(y).
