PHP trim() function in Actionscript for Flex

Kerk — Sat, 06 Sep 2008 23:23:00 +0000

Here is PHP’s trim() function reproduced in Actionscript for use in a Flex application

public function trim(str:String):String
{
  for(var i:Number = 0; str.charCodeAt(i) < 33; i++);
  for(var j:Number = str.length-1; str.charCodeAt(j) < 33; j--);
  return str.substring(i, j+1);
}

UPDATE: Thanks to Almog Kurtser, I now know that Flex has a utility to handle trimming strings. Here is an alternative example

import mx.utils.StringUtil;
public function trim(str:String):String
{
  return StringUtil.trim(str);
}

Of course it is redundant to actually create a function called trim just to call the method StringUtil.trim() but you get the idea.

If you’re a long time PHP programmer who has made the leap to building Flex based RIA applications in Flex you are probably asking yourself from time to time “how do I do a xxxxx function in actionscript”. Well if you were recently wondering this about the PHP explode() function, here’s your answer.

public function explode( delimiter:String, str:String ):Array
{
   return str.split( delimiter );
}

Use a remote HTTPService in Flex with a PHP Proxy

Kerk — Thu, 28 Feb 2008 11:43:00 +0000

One way to get around the hassle of a common security error when trying to call a HTTPService running on a different domain than your Flex application is to use a simple and local PHP script as a proxy to call the HTTPService for you. Perhaps not a solution you would want to use if you need to load massive piles of data but in most cases it works just fine and takes seconds to set up.

proxy.php

$content = file_get_contents(str_replace(' ','%20',$_GET['url']));if ($content !== false) {   echo($content);} else {  // there was an error}

PHP in_array() function in ActionScript for Flex

Kerk — Fri, 22 Feb 2008 02:10:00 +0000

Another common PHP function is in_array() used to determine if a value exsists in an array. Here is the function recreated in actionscript for flex.

public function in_array( needle:*, haystack:Array ):Boolean{   var itemIndex:int = haystack.indexOf( needle );   return ( itemIndex < 0 ) ? false : true;}

PHP ucfirst() and ucwords() in Flex

Kerk — Tue, 19 Feb 2008 03:17:00 +0000

Another common PHP function converted to ActionScript for use in a Flex application.

public function ucfirst( str:String ):String{  return str.substr(0,1).toUpperCase()+str.substr(1);}public function ucwords( str:String ):String{  var myArr:Array = str.split(' ');  for (var i:int in myArr ) {     myArr[i] = ucfirst( myArr[i] );  }  return myArr.join(' ');}

PHP strtoupper() and strtolower() in Flex

Kerk — Tue, 19 Feb 2008 03:07:00 +0000

Having been a PHP programmer for many years and only now in the last month started to learn Flex and ActionScript I find I’m always looking for ways to get something done in ActionScript which I know how to do in PHP. These are pretty straight forward and simple functions but sometimes it’s nice to have a reference.

PHP strtoupper( $string ) and strtolower( $string ) in Flex

public function strtoupper( str:String ):void{ return str.toUpperCase();}   public function strtolower( str:String ):void{ return str.toLowerCase();}

String Replace Function in Flex

Kerk — Sat, 16 Feb 2008 03:20:00 +0000

I’m not sure if this is a redundant function or not. I know that Flex String objects have a replace() method but as far as I can tell this only replaces the first match and not every match in a string.

Here is an actionscript function for flex which works the same as the php str_replace() function.

str_replace( needle, replacement, haystack ) in ActionScript

public function str_replace(needle:String, replacement:String, haystack:String):String{  var strArr:Array = haystack.split(needle);  return strArr.join(replacement);}

If this is a pointless function and there is an easier way to accomplish this built into flex I would love to hear about it. I looked over the language reference documents and couldn’t find something.
