Using two arrays with different keys in an mysql update query - php

Question

I have a array like this
$outputs:
269 => string ' SUN: 2.495' (length=13)
510 => string ' SUN: 1.416' (length=13)
Another Array like this
$filenames:
0 => string 'Hi35
' (length=5)
1 => string 'He_41
' (length=6)
And to update the respective values i tried writing a code like
foreach($outputs as $key => $value){
$sql = "UPDATE Store SET D='".$value."' WHERE `Index` = '".$filenames[$key]."'";
mysql_query($sql);
}
But then there is no $filenames[$key] value, because the key value for $outputs starts with 269. This is only one case, the key value could be anything.
I also tried the other way around. i.e.
I combined both the array first
$arr3 = array_combine($outputs, $filenames);
And then tried to Put the combined array in SQL query like
foreach($arr3 as $key => $value){
$sql = "UPDATE Store SET D='".$key."' WHERE `Index` = '".$value."'";
mysql_query($sql);
}
BUT this dint work.. A help from your side will really be appreciated...

Answer 1

You can do something like this
$outputs = array(
'269' => 'SUN: 2.495',
'510' => 'SUN: 1.416'
);
$filenames = array(
'0' => 'Hi35',
'1' => 'He_41'
);
$array_complete = array_combine($filenames, $outputs);
foreach($array_complete as $key => $val)
{
echo "UPDATE Store SET D='".$val."' WHERE `Index` = '".$key."'" . '<br>';
}
This will output
UPDATE Store SET D='SUN: 2.495' WHERE `Index` = 'Hi35'
UPDATE Store SET D='SUN: 1.416' WHERE `Index` = 'He_41'
Then I would like to remember you that mysql_ functions are deprecated so i would advise you to switch to mysqli or PDO

Your code doesn't look good at all mate, but here is a hack for that:
$num_outputs = count($outputs);
$index = 0;
foreach($outputs as $key => $value) {
$sql = "UPDATE Store SET D='".$value."' WHERE `Index` = '".$index."'";
mysqli_query($sql);
$index++;
}
