Why does this print 42:
$answer = 42;
$variable = "answer";
print ${$variable} . "\n";
but this doesn't:
my $answer = 42;
my $variable = "answer";
print ${$variable} . "\n";

I need to access a javascript variable with php. Here's a stripped-down version of the code I'm currently trying, which isn't working:
<script type="text/javascript" charset="utf-8">
var test = "tester";
</script>
<?php
echo $_GET['test'];

I'm a complete noob at both js and php, so would really appreciate any advice.

I'm using a nice plugin I got from http://www.webmotionuk.co.uk/php-jquery-image-upload-and-crop/
It's nice and all, but it doesn't solve a particular problem: I'll have users uploading images of differing sizes and aspect ratios, so, here's what they provided:

Say I have a couple of java runtime environments running on my system which are used by several applications. I would like to programmatically interact with these applications by reading their memory.
A typical approach would be to directly look into this application's memory, however for java applications this seems to be practically i...
I just need some clarification on variables
A normal variable has 2 "parts" to it?
one part is the actual value and the other part is the location of that value in the memory
Is that right?
So a pointer variable is just the location part of a normal variable, and it doesn't have value itself?

I'm working on a 2 page form that POSTs a query to a database. Read-only, no writing. None of the information is confidential, nor will it every be.
The site must be 100% non-JS compliant, so Ajax and the like are not available. All I got is PHP, baby!
FORM-2's content is dependent on a fraction of the data in FORM-1, but ALL of the da...

My thoughts on how to grab all scalers and arrays out of perl file went along the lines of:
open (InFile, "SomeScript.pl");
@InArray = <InFile>;
@OutArray = {};
close (InFile);
$ArrayCount = @InArray;
open (OutFile, ">outfile.txt");
for ($x=0; $x<=$ArrayCount; $x++){

I've learned how to store a single input of data and return a value based on it.
What I want to do is obtain multiple inputs from the user, then return a result. But how do I define each input?
Like, if I want the first input to be known as 'stock', and the second as 'value', how do I do that?
I hope I explained my question properly....
int a = 1, b;
if(a > 0) b = 1;
if(a <= 0) b = 2;
System.out.println(b);
If I run this, I receive:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The local variable b may not have been initialized
at Broom.main(Broom.java:9)
I know that the local variables are not initialized and is your duty to do t...
i'm loading several sound files, and want to error check each load. however, instead programming each one with their own complete/error functions, i would like them to all use the same complete/error handler functions.

I have created a rudimentary EasterEgg within my code to activate when the following keystrokes are made (not simultaneously) Enter + c + o + l + o + r + s with the following code:

I have multiple models that I want to create generic inputs for. My first pass used two separate urls:

var id = $(this).children().html(); // id is 5

url: 'ajax.php?id=' + id,
success: function(data) {
id = data; // id is 1
}
});

}
Why in the following example I can't reinitialize the id variable? What is wrong?
Thanks.
