[SOLVED] GET['var'] in the url

[ohdang888]

i know how to get the variable in the URL such as index.php?show_all=true

 

but how woudl i get it if i just want to put "index.php?show_all"????... want to see if "show_all" exists in the url

 

thanks!

all the vars past through the url are stored in the $_GET array.

[ohdang888]

so what would i do...

 

$_GET['show_all'] ???

 

cause there is no definng what show all is, its just simple "show all"

[.josh]

..is "show_all" a specific variable, or are you wanting to "show all" as in find out what all your variables are?

 

if it's a specific variable, you'd access it by

echo $_GET['show_all'];  // this echo's the value of the variable

 

if you are wanting to find out what variables are being passed in your url, $_GET is an array of those variables you'd access them any number of ways here's an example of how to echo them:

 

foreach ($_GET as $key => $val) { 
   echo $key . " = " . $val . "<br>";
}

 

If neither of these is what you mean, then please clarify some more.

He means index.php?show_all, not index.php?show_all=true.  Unless a parameter has a value in a URL, it doesn't get a spot in $_GET.

 

echo $_SERVER['QUERY_STRING']; //would echo show_all if it was index.php?show_all
