Editing MySql results array problem

Copy linkTweet thisAlerts:
Jun 03.2009

Basically what I want to do is edit the results array that gets returned after a MySql call. Here is what I am currently doing:

[code=php]
while($myrow = mysql_fetch_array($result))
{
$zipcode = $myrow[‘Zip’];
$miles = $zips[$zipcode]; // returns how far the zipcode is from the destination
$result[$count][‘Zip’] = $miles;
$count++;
}
[/code]

I get the PHP error messager “Warning: Cannot use a scalar value as an array” when executing this code because apparently $result isn’t an array. Any advice?

@themartyJun 03.2009 — Not only is $result not an array, it's also the variable with a pointer to the resultset: if you would overwrite it the while-loop would quit after just one iteration. So, before the while-loop, initiate a new array like this:
[code=php]$someNameThatMakesSenseArray = array();[/code]
And use that one to store the information.

So, something like this:

[code=php]$someNameThatMakesSenseArray = array();
$count = 0;
while($myrow = mysql_fetch_array($result))
{
$someNameThatMakesSenseArray[$count++] = array(
"Zip" = $zips[$myrow['Zip']];
);
}[/code]

Btw, count doesn't really do anything extra here. You could also write this as:

[code=php]$someNameThatMakesSenseArray = array();
while($myrow = mysql_fetch_array($result))
{
$someNameThatMakesSenseArray[] = array(
"Zip" = $zips[$myrow['Zip']];
);
}[/code]

Success!
