then
curl -k 'http://www.myserver.com/log.cgi?input=$?'
echo "hi there"

sed -n -e '/regex/{$!N;p;}'

parse_str
PARSE_STR(3) 1 PARSE_STR(3)parse_str - Parses the string into variablesSYNOPSIS
void parse_str (string $str, [array &$arr])
DESCRIPTION
Parses $str as if it were the query string passed via a URL and sets variables in the current scope.
Note
To get the current QUERY_STRING, you may use the variable $_SERVER['QUERY_STRING']. Also, you may want to read the section on vari-
ables from external sources.
Note
The magic_quotes_gpc setting affects the output of this function, as parse_str(3) uses the same mechanism that PHP uses to populate
the $_GET, $_POST, etc. variables.
PARAMETERS
o $str
- The input string.
o $arr
- If the second parameter $arr is present, variables are stored in this variable as array elements instead.
RETURN VALUES
No value is returned.
EXAMPLES
Example #1
Using parse_str(3)
<?php
$str = "first=value&arr[]=foo+bar&arr[]=baz";
parse_str($str);
echo $first; // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz
parse_str($str, $output);
echo $output['first']; // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz
?>
