Using $_GET funcion instead of using plain text - php

Question

I have a file on my server called "form2.php", this is what it looks like:
<form action="strlen2.php" method="get">
<input type="text" name="text13"/>
<input type="submit" value="Submit!"/>
</form>
I have it transfer to another file called "strlen2.php", this is what it looks like:
<?php
$text="$_GET["text13"]";
$more="Too much! Take away some text.";
$equal="Great! You entered the right amount.";
$less="Not enough! Enter some more text.";
if(strlen($text)>3)
{
echo $more;
}
elseif(strlen($text)==3)
{
echo $equal;
}
else
{
echo $less;
}
?>
What can I change on line 3 that makes it execute the $_GET function instead of looking at it as plain text?

Answer 1

$_GET is a variable. Remove the quotes around it.
$text = $_GET['text13'];

Answer 2

In PHP, the predefined $_GET variable is used to collect values in a form with method="get".
<form action="strlen2.php" method="get">
and if you do print_r($_GET); in your strlen2.php, you'll be able to see the result.

Answer 3

Remove the quotes. $_GET is not a function, but an array.
$text = $_GET["text13"];

Answer 4

If the value of $_GET['text13'] DOES happen to contain a reference to a function, you would need to do something like this:
$text = $_GET['text13'];
$text();

Answer 5

$_GET is not a function ;) it's a variable. Remove the quotes and it should work like a charm :)
eg :
$text=$_GET["text13"];
$more="Too much! Take away some text.";
$equal="Great! You entered the right amount.";
$less="Not enough! Enter some more text.";

Answer 6

<?php
$text = $_GET["text13"];
....
Don't put quotes around the assignment!

Answer 7

This would never work:
$text="$_GET["text13"]";
Use this instead:
$text = $_GET['text13'];

Answer 8

Try this:
$text= $_GET["text13"];
