As long as allow_url_fopen is enabled in your php.ini configuration you can use HTTP and FTP urls with a majority of the functions that use a filename as a parameter.

I found that there are 3 ways to read remote files using PHP.

Fopen

if ($filepointer = fopen("http://banditrevolvers.com", "r")) {
     $site_content = "";
 
     //While we still have content to read, append it
     //1k at a time
     while ($line = fread($filepointer, 1024) {
          $site_content .= $line;
     }
 
} else {
     //Error occured while trying to read the url
}
 
fclose($filepointer);

Another example using fgets instead of fread

if ($filehandle = fopen("http://banditrevolvers.com", 'r') {
 
     while(!feof($filehandle)) {
          $readline = fgets($filehandle, 1024);
          if (eregi("<title>(.*)</title>", $readline, $output) {
               $title = $output[1];
               break;
          }
     }
} else {
     //Error occured while trying to read the url
}
 
echo "Title of the page is: " . $title;
 
fclose($filehandle);

Wait what's the difference between fgets and fread?

Glad you noticed that. The truth is that fread is the more preferable function to use when reading (or in this case streaming) data from a remote file. The reason is because the fgets function reads a line at a time. For example, if you had a 2000 line file that was only 35k in size, it would loop 2000 times with fgets. However it would only loop 35 times with fread (assuming a 1k buffer).

Then again, if you need to read a file one line at a time fgets is the function you'll need.

File_get_contents

This function will return the contents of a file in a string. To use it just specify a URL as a parameter. Be sure to check the return value to see if it was successful or not.

$content = file_get_contents("http://banditrevolvers.com");
 
if ($content !== false) {
     //Do something with the content
} else {
     //An error occurred
}

CURL

Not all web hosts have the CURL library in their installation. Thus we have to check to see if the function exists before we attempt to use it.

if (function_exists('curl_init')) {
     //Initialize a new resource for curl
     $ch = curl_init();
 
     //Set the url the retrieve
     curl_setopt($ch, CURLOPT_URL, 'http://banditrevolvers.com');
 
     //Return the value instead of outputting to the browser
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 
     $contents = curl_exec($ch);
     curl_close($ch);
 
     if ($contents) {
          //Do stuff with the contents
     } else {
          //Show error message
     }
 
}

In AS2, setting the onPress event for a MovieClip would automatically cause the cursor to switch the hand whenever you hovered over the element. However in AS3 I discovered that in order to get the same functionality it has to be done manually to get the same effect:

//These are properties of the MovieClip class
targetMc.buttonMode = true;
targetMc.useHandCursor = true;

Upon discovering this bit of code, I noticed that I had already created more than a dozen of clickable instances that could use this code and not all of them had classes for them. I had searched for some kind of global variable that I could set to see if I could get this working with all of them the easy way. Alas, I came up with nothing. So instead I decided to create a base class to implement this functionality for me.

import flash.display.MovieClip
 
package com.jelaniharris {
     class ButtonMovieClip extends MovieClip {
          //Override the default constructor and make this movieclip indicate it's a button to the user
          public function ButtonMovieClip (): void {
               this.buttonMode = true;
               this.useHandCursor = true;
          }
     }
}

Then all I needed to do was to go to my library and set the Base Class of all of my button-like elements to the ButtonMovieClip class.

I hoped this helped someone out there.

//Bind this keypress function to all of the input tags
$("input").keypress(function (evt) {
//Deterime where our character code is coming from within the event
var charCode = evt.charCode || evt.keyCode;
if (charCode  == 13) { //Enter key's keycode
return false;
}
});

By returning false in the keypress function it tells the browser not to allow the enter key event.

In PHP

    foreach ($my_array as $key => $value) {
      //We check to make sure that the value is either null or just an empty string
      if (is_null($value) || $value=="") {
        unset($my_array[$key]);
      }
    }

An easier way to clean arrays is to use php's array_filter function without a callback parameter. By default that function is set to remove elements that contain a false (or a 0), null or a "". I mean seriously, look at how much cleaner it is:

   //This prunes out 'false', '0', 'null' or ''
   $my_array = array_filter($my_array);

In JavaScript

We can mimic the functionality of Php's array_filter in Javascript by using the Array.filter function.

   var my_array = [1,2,3,'4','', 0, null, 'false'];
   function emptyElement(element) {
	//Removes nulls, zeros (also falses), text version of false, and blank element
	if (element == null || element == 0 || element.toString().toLowerCase() == 'false' || element == '')
		return false;
		else return true;
	}
 
	var my_array = [0,'false',1,null, 2,'',3,'4',false];
	my_array = my_array.filter(emptyElement);
   }

Then my_array will include 1,2,3,4.

I hope this was somewhat useful.

Honestly .. I'm not sure why. But, here's how you can make it perform better.

Here's how to speed up flash CS3 for vista

1. Navigate to your Program Files -> Adobe folder(s) -> Adobe Flash CS3 and find the Flash.exe.
2. Right click on that file and goto the Compatibility tab.
3. Check "run this program in compatibility mode", and voila, suddenly it's running as fast as it did on XP. Happy coding!

String sentence = "The sly brown fox jumped over the lazy fox.";
String result = sentence.replaceAll("fox", "doggie");
System.out.println("Input: " + sentence);
System.out.println("Output: " + result);

Would output:

Input: The sly brown fox jumped over the lazy fox.
Output: The sly brown doggie jumped over the lazy doggie.

However there are cases where we want to replaceall substrings and ignore the case, or make it case insensitive.

String sentence = "The sly brown Fox jumped over the lazy foX.";
String result = sentence.replaceAll("fox", "dog");
System.out.println("Input: " + sentence);
System.out.println("Output: " + result);

Input: The sly brown Fox jumped over the lazy foX.
Output: The sly brown Fox jumped over the lazy foX.

To create the case sensitive version of replaceAll we do not need to create a new wrapper function or create a utility class somewhere. All we need to do is prepend the Case-insensitve pattern modifier (?i) before our regex to indicate that we don't care about the case sensitivity of the regex.

String sentence = "The sly brown Fox jumped over the lazy foX.";
String result = sentence.replaceAll("(?i)fox", "dog");
System.out.println("Input: " + sentence);
System.out.println("Output: " + result);

Input: The sly brown Fox jumped over the lazy foX.
Output: The sly brown dog jumped over the lazy dog.
