make multilevel array from mysql php - php

Question

i have this array in an example, how can i get the same result from query from database?, i need to replace the values which the values of the database.
$data = array(
array(
'qty' => 1,
'Price' => 1.00,
'total' => 1.00
),
array(
'qty' => 2,
'Price' => 1.00,
'total' => 2.00
),
array(
'qty' => 3,
'Price' => 1.00,
'total' => 3.00
)
);
then in the example use the nusoap lib
foreach($data as $concept) {
$par['Concepts'][] = new soapval('Concept', 'Concept', $concept);
}
so i need to call the query:
$query_data_cot = mysql_query("SELECT * FROM data WHERE id='1'");
while($data_quote=mysql_fetch_array($query_data_cot)){
$conceptosDatos[]["qty"]=$data_quote['qty'];
$conceptosDatos[]["Price"]=$data_quote['price'];
$conceptosDatos[]["total"]=$data_quote['total'];
}
but when i do these i got an error
Error: Array ( [faultcode] => soap:Server [faultstring] => Server was unable to process request. --->
thank you

Everytime you use $conceptosDatos[]... the [] will create a new subarray. So your result will be something like this
array(
array('qty' => ..),
array('Price' => ..),
array('total' => ...),
array('qty' => ..),
array('Price' => ..),
array('total' => ...),
...
)
Instead you need to create a new subarray only for a whole set, so use something like this
$query_data_cot = mysql_query("SELECT qty, price, total FROM data WHERE id='1'");
while($data_quote=mysql_fetch_assoc($query_data_cot)){
$conceptosDatos[] = $data_quote;
}
Of course you could also do it like this
$query_data_cot = mysql_query("SELECT qty, price, total FROM data WHERE id='1'");
while($data_quote=mysql_fetch_assoc($query_data_cot)){
$conceptosDatos[] = array(
'qty' => $data_quote['qty'],
'Price' => $data_quote['price'],
'total' => $data_quote['total'],
);
}
But why write every field if you're going to copy the whole array anyway?
If you need to use different names (as in your example price and Price), you can either change your db schema or use aliases in your query, giving you this code:
$query_data_cot = mysql_query("SELECT qty, price AS Price, total FROM data WHERE id='1'");
while($data_quote=mysql_fetch_assoc($query_data_cot)){
$conceptosDatos[] = $data_quote;
}
This has the advantage that if you wish to modify your code in the future, you'd only need to modify the query (and could probably encapsulate this logic inside a function) - so less work for future you.
By the way, did you see the big red box in the manual on all mysql_* methods's sites? It's deprecated and PDO as well as MySQLi are way better alternatives. This helps decide what to use.

Try this , while($data_quote=mysql_fetch_array($query_data_cot , MYSQL_ASSOC )) , as you are retrieving the $data as an associative array .

Answer 3

Each assignment line in your loop is creating a new element of the $conceptDatos array, not filling in a different element of the same element. So your array looks like:
array(
array('qty' => 1),
array('Price' => 1.0),
array('total' => 1.0),
array('qty' => 2),
array('Price' => 1.0),
array('total' => 1.0),
...
)
Your loop shoud be:
while($data_quote=mysql_fetch_array($query_data_cot)){
$conceptDatos[] = array(
'qty' => $data_quote['qty'],
'Price' => $data_quote['price'],
'total' => $data_quote['total']
);
}
