PHP Text Flipper Library

Have you seen some cool webapps where you can write English texts upside down?

I have found out the techniques. They just use some Unicode characters to do the trick. Unicode has a vast collection of characters and you have to find the right one that looks like an upside down english character.

I have written a PHP library to do the job .
Visit the demo at:
https://masnun.com/flipper/ 😀
Download the Library at:
http://masnun.googlecode.com/files/flipper.php 🙂

Here’s the source code of the demo:

<?php
header("Content-type: text/html; charset='utf-8'");
echo "<html><head>
<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\">
<title>maSnun's string flipper</title><body>
<form action=\"index.php\" method=\"POST\">
<b>Enter a string:</b><br />
<input type=\"text\" name=\"string\" value=\"{$_POST['string']}\">
<input type=\"submit\" value=\"flipNow()\">
</form><br /><br />";

if(isset($_POST['string'])) {
include('flipper.php');
$stringFlipper = new StringFlipper;
$str = $stringFlipper->flipString($_POST['string']);
echo "<b>Flipped String:</b><input type=\"text\" value=\"$str\"> <br /><br />";

}

echo "</body><html>";

?>

<?php

header("Content-type: text/html; charset='utf-8'");

echo "<html><head>

<title>maSnun's string flipper</title><body>

<b>Enter a string:</b><br />

</form><br /><br />";

if(isset($_POST['string'])) {

include('flipper.php');

$stringFlipper = new StringFlipper;

$str = $stringFlipper->flipString($_POST['string']);

echo "<b>Flipped String:</b><input type=\"text\" value=\"$str\"> <br /><br />";

}

echo "</body><html>";

PS: PHP and web browsers have some issues regarding Unicode data. So please ensure the “Content-type” is set to “text/html” and the charset is “utf-8” 🙂

Happy flipping 😀

PHP DOM and XPATH

After checking out beautifulsoup in Python, I became very curious to know what we have in PHP for accessing the DOM nodes of a html document. After exploring a while, I found out the PHP DOM and XPATH.

Here’s a little example:

masnun.html – The HTML file

<html>
<head>
<title>
DOM Test
</title>
<body>
<font size="3">maSnun <a href="https://masnun.com">masnun.com</a></font>
</body>
</html>

<html>

<head>

<title>

DOM Test

</title>

<body>

<font size="3">maSnun <a href="https://masnun.com">masnun.com</a></font>

</body>

</html>

Now we use PHP to access the document:

#!/usr/bin/php

<?php
$dom = new DOMDocument; // construct a DOMDocument element
$dom->loadHTML(file_get_contents("masnun.html")); // load the contents of the html file
$xpath = new DOMXPath($dom); // build a new DOMXPath element with the loaded DOMDocument

// define the search pattern now
// here we search for every <a> tag
// inside <font> tags which have a
// attribute, size = 3
// the <font> tags would be under
// the <body> tag

// the pattern is quite easy to understand
// and I find it quite identical to the linux
// filesystem structure

$pattern = "/html/body/font[@size=3]/a";


$res = $xpath->evaluate($pattern); // use the evaluate method to get a DOMElement object

//Now, lets play with the objects
// Please see the DOMElement part of PHP Manual
// to get the details on the methods I have used here

for($i=0;$i < $res->length; $i++) { echo $res->item($i)->getAttribute("href"); }

?>

#!/usr/bin/php

<?php

$dom = new DOMDocument; // construct a DOMDocument element

$dom->loadHTML(file_get_contents("masnun.html")); // load the contents of the html file

$xpath = new DOMXPath($dom); // build a new DOMXPath element with the loaded DOMDocument

// define the search pattern now

// here we search for every <a> tag

// inside <font> tags which have a

// attribute, size = 3

// the <font> tags would be under

// the <body> tag

// the pattern is quite easy to understand

// and I find it quite identical to the linux

// filesystem structure

$pattern = "/html/body/font[@size=3]/a";

$res = $xpath->evaluate($pattern); // use the evaluate method to get a DOMElement object

//Now, lets play with the objects

// Please see the DOMElement part of PHP Manual

// to get the details on the methods I have used here

for($i=0;$i < $res->length; $i++) { echo $res->item($i)->getAttribute("href"); }

That’s it, pretty simple and easy ! 😀

Wishing you all a very happy Eid Day 🙂

PHP:

<?php 
class Eid 
{
    public function Mubarak() 
    {
        echo __CLASS__." ".__FUNCTION__;
    }
}
$eid = new Eid;
$eid->Mubarak();
?>

<?php

class Eid

{

public function Mubarak()

{

echo __CLASS__." ".__FUNCTION__;

}

$eid = new Eid;

$eid->Mubarak();

Python:

#!/usr/bin/env python

import inspect

class Eid:
	def Mubarak(self):
		print self.__class__.__name__, str(inspect.stack()[0][3])

eid = Eid()
eid.Mubarak()

#!/usr/bin/env python

import inspect

class Eid:

def Mubarak(self):

print self.__class__.__name__, str(inspect.stack()[0][3])

eid = Eid()

eid.Mubarak()
