Removing the last part of $QUERY_STRING

[Anon]

Hi,

How can I remove the last part of a given QUERY_STRING, if I know the name of the last
variable, but not it\'s value?

For example if I have the following QUERY_STRING :

var1=1&var2=x

Here I want to remove the \"&var2=x\" part..

Any idea?

Thanks

var1=1&var2=x

Here I want to remove the \"&var2=x\" part..

You can use the spilt() function (http://www.php.net/manual/function.split.php). This function will split the string into an array based on the pattern you specify.

For example:

<?

  $query = "var1=1&var2=x";

  $split_query = split("&", $query, 2);

  echo "$spilt_query[0]<br>";
  echo "$spilt_query[1]<br>";

?>

Hope tjios helps.........

Or you could use eregi_replace to get rid of the nasty variable. An added advantage of this is that it doesn't matter where the variable is; you only have to know its name.

<?

$vars = $QUERY_STRING;

$newquery = eregi_replace ("&var2=$var2","",$vars);

?>

This works like a dream for me.
