I'm getting a return string from a merchant account that looks like:
RecurringID=8675309&RefNo=41:39&Notes=
so I parse it into an array like this:
$results = array();
$temp = explode('&', $temp);
foreach($temp as $line)
{
$line = explode('=', $line);
$results[trim($line[0])] = trim($line[1]);
}
The resulting prin开发者_如何学运维t_r($results); produces this:
Array ( [RecurringID] => 8675309 [RefNo] => 41:39 [Notes] => )
And yet when I try this:
$blah = $results['RecurringID'];
I get:
Notice (8) : Undefined index: RecurringID
I can't reproduce this error. Are you using it it before the RecurringID index is defined?
Do you know about parse_str()
$temp = 'RecurringID=8675309&RefNo=41:39&Notes=';
parse_str($temp, $results);
print "<pre>";
print_r($results);
print "</pre>";
$results has this in it:
Array
(
[RecurringID] => 8675309
[RefNo] => 41:39
[Notes] =>
)
This works fine:
print $results['RecurringID']; //8675309
I can't replicate your warning even if I add:
error_reporting(E_ALL);
...above everything else.
Aha! My problem was outputing it to the browser, I couldn't see the full return value. Turns out looking at the ascii values reveals:
\r\n\t\t<html><body>RecurringID=1488819&RefNo=186:192&Notes=</body></html>
Which apparently was confusing parse_str and my manual method for parsing.
