Create a php array with keys and values from mysql query - php

Question

I'm trying to store my mysql query in an array like this :
$arr = array ( "field1"=>"value" , "field2"=>"value" , "field3"=>"value" , ... );
I've tried this but don't work like I need :
$row_selectProduct = array();
$sResult = $db->query( 'SELECT * FROM tbl' )
while ( $aRow = $sResult->fetch_assoc() )
{
$sInfo = $sResult->fetch_field();
// General output
$row_selectProduct[ $sInfo->name ] = $aRow;
}
$sResult->close();
Thx for help
EDIT :
Sorry for misunderstanding...
I'd like to name keys by the field name in database.
I try to reproduce this :
$result = array();
while ($row_selectProduct = mysql_fetch_assoc($selectProduct));
{
$row_array= array();
$row_array['field_name1_In_DB'] = $row_selectProduct['field_name1_In_DB'];
$row_array['field_name2_In_DB'] = $row_selectProduct['field_name2_In_DB'];
$row_array['field_name3_In_DB'] = $row_selectProduct['field_name3_In_DB'];
$row_array['field_name4_In_DB'] = $row_selectProduct['field_name4_In_DB'];
$row_array['field_name5_In_DB'] = $row_selectProduct['field_name5_In_DB'];
...
array_push($result,$row_array);
};

Answer 1

Using PDO connection functions, it's quite simple --
foreach($db->query('SELECT field_name1,field_name2 FROM table') as $row) {
echo $row['field_name1'].' '.$row['field_name2']; //etc...
}
Here's a good tutorial for PDO in PHP if you want more.

while ( $aRow = $sResult->fetch_assoc() )
{
foreach($aRow as $fieldname => $fieldvalue) {
$row_selectProduct[$fieldname] = $fieldvalue;
}
}
but you will overwrite your $row_selectedProduct with every record and the var at the end will only have stored the last record
if you would like to have all results in one array you should:
$results = array();
while ( $aRow = $sResult->fetch_assoc() )
{
$results[] = $aRow;
}
if you know that there will be only one result you need only:
$result = $sResult->fetch_assoc();
