Top Forums Shell Programming and Scripting perl scalar variable in backquoted string Post 302139181 by mehdi9 on Thursday 4th of October 2007 05:07:28 PM
ok so I tried the echo function:

Code:
`echo my variable $myvar >> $tempfile`;

unforutunatly nothing comes up, not even the "my variable" part

I tried the following

Code:
$myvar2 = "abcdefghi";

`echo my variable two is $myvar2 >> $tempfile`;

and it comes up in the array.

so my question is, how can I gather the exact word the 'add' popup menu is selected on?

if you look at the array @addvar, the entry $myvar (which equals to param('add')) comes up, however when used in the backquoted string it doesn't work. Can someone please clarify why this is. Many thanks.

parse_str - Parses the string into variables

SYNOPSIS
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 ?> SEE ALSO
parse_url(3), pathinfo(3), http_build_query(3), get_magic_quotes_gpc(3), urldecode(3). PHP Documentation Group PARSE_STR(3)
