how to update table from array multidimension with php - php

how can i update data from array multidimension in php, but its from key and value array like this :
$array1=array(
array('data1'=>'name','data2'=>'age'),
array('data1'=>'names','data2'=>'ages')
);
how can i get result from array like this
UPDATE tablename SET data1='name',data2='age' WHERE 1;
i tried this but the result not like above
foreach($array1 as $arrays) {
foreach($arrays as $key => $value){
echo $key."="."'".$value."'".", ";
}
}
result:
data1='name',data2='age', data1='name',data2='age'
i want result like this :
data1='name',data2='age'
i hope can help me.

Because you only want to get content of first array, you should loop through first array only
foreach($array1[0] as $key => $value){
echo $key."="."'".$value."'".", ";
}
// data1='name', data2='age',

merge array inside foreach loop

I want to merge array result inside foreach loop. Is there any solution about this or other best way. Thanks in advance.
PHP code
include('Config.php');
$data = json_decode(file_get_contents("php://input"));
foreach($data->dataVal as $key => $value){
echo json_encode($config->query($key,$value));}
//this is the response code above --> how to merge this 2,3 array result into one only
[{"name":"Roi"}][{"name":"Tom"}][{"name":"Chad"}]
//result to be expected like this
[{"name":"Roi","name":"Tom","name":"Chad"}] // this is i want
The nearest you will get is by building up an array of the data in the foreach loop and JSON encoding the result...
$result = array();
foreach($data->dataVal as $key => $value){
$result[] = $config->query($key,$value);
}
echo json_encode($result);
This stops having repeated values for the name.
In your original attempt, you were encoding each row separately, so the JSON was invalid.

how to replace value with spesific column with searching id on array

i have some problem with data array, how to replace spesific array column with searching in column id in array
data json array like this :
$json ='
[
{"id":1,"name":"Eko","approved":"n"},
{"id":2,"name":"Rudi","approved":"n"},
{"id":3,"name":"Yanto","approved":"n"}
]
';
ihave tried many tutorial but not spesific replace array
iwant output like this :
$json =
'
[
{"id":1,"name":"Eko","approved":"n"},
{"id":2,"name":"Rudi","approved":"y"},
{"id":3,"name":"Yanto","approved":"n"}
]
';
i apreciate with your help
defferent is "approved":"y" in json2
$array = json_decode($json);
foreach ($array as $key => $item) {
if($item->id == $your_serach_id){
$array[$key]->approved = "y";
}
}
I hope this helps.
You can tirverse the JSON object using for loop or foreach look and fetch the key value pair in the array and for getting your desired output you will need to know the value of which key you have to change so in the loop you can array[i] ->key = new_valuethis line should be thier after if condition in for loop

Multidimensional array - how to get specific values from array

I have converted Excel data into Php array using toArray()..
actually my result is
My question how to get value from this Multidimensional array? and also how to i get header and value from array in separately?
you can access value, by following the path of the array. so in your case :
$yourArrayName['Worksheet'][0][0], will return SNo
Get one value:
print_r($your_array['Worksheet'][0]);
Get values with loop:
foreach ($your_array as $key => $value)
{
echo $key; // 'Worksheet'
print_r $value;
}
If you are trying to extract all the values of specific key then you should use for or foreach or while loop...
its something like
<?php
$array = YOUR ARRAY;
$c=count($array);
for ( $i=0; $i < $c; $i++)
{
echo $array[$i]['StudentName'];
}
?>
else if you want to get a specific value manually You can easily traverse to your value as
$array = YOUR ARRAY
echo $ara['Worksheet'][0]['StudentName']

PHP removing elements from array in a foreach loop

I'm trying to unset() some elements from an array but when using a foreach loop to go through 1 array to delete these elements from another array it does not seems to be working.
if (isset($this->request->post['merge'])) {
$merge_orders = $this->request->post['merge'];
}
$selected_order = min($merge_orders); // Fetch the max value order_id
unset($merge_orders[$selected_order]); // Take it out of the array.
$orders_list = explode(',', $this->request->post['order_id_list']);
$removeKeys = $merge_orders;
foreach($removeKeys as $key) {
unset($orders_list[$key]);
echo $key;
}
echo print_r($orders_list);
The first unset works fine but the second does not, the array is set and properly formatted but it still does not seem to remove the elements from the $orders_list array.
If you only use one parameter on a foreach loop you are delivered the value of the occurance and not the key for the occurance.
Try this so that you are getting a key from the foreach loop and not a value
foreach($removeKeys as $key => $val) {
unset($orders_list[$key]);
echo $key;
}

Adding key=>value pair to existing array with condition

Im trying to add a key=>value to a existing array with a specific value.
Im basically looping through a associative array and i want to add a key=>value foreach array that has a specific id:
ex:
[0] => Array
(
[id] => 1
[blah] => value2
)
[1] => Array
(
[id] => 1
[blah] => value2
)
I want to do it so that while
foreach ($array as $arr) {
while $arr['id']==$some_id {
$array['new_key'] .=$some value
then do a array_push
}
}
so $some_value is going to be associated with the specific id.
The while loop doesn't make sense since keys are unique in an associative array. Also, are you sure you want to modify the array while you are looping through it? That may cause problems. Try this:
$tmp = new array();
foreach ($array as $arr) {
if($array['id']==$some_id) {
$tmp['new_key'] = $some_value;
}
}
array_merge($array,$tmp);
A more efficient way is this:
if(in_array($some_id,$array){
$array['new_key'] = $some_value;
}
or if its a key in the array you want to match and not the value...
if(array_key_exists($some_id,$array){
$array['new_key'] = $some_value;
}
When you use:
foreach($array as $arr){
...
}
... the $arr variable is a local copy that is only scoped to that foreach. Anything you add to it will not affect the $array variable. However, if you call $arr by reference:
foreach($array as &$arr){ // notice the &
...
}
... now if you add a new key to that array it will affect the $array through which you are looping.
I hope I understood your question correctly.
If i understood you correctly, this will be the solution:
foreach ($array as $arr) {
if ($arr['id'] == $some_id) {
$arr[] = $some value;
// or: $arr['key'] but when 'key' already exists it will be overwritten
}
}
