In PHP you can get contents of an output buffer using ob_get_contents(). The usage is given below:

ob_start();
echo "Schogini Inc";
$out_buffer = ob_get_contents();
ob_end_clean();
var_dump($out_buffer);

That’s it.

For Truecolor images the colors are simple 31-bit longs. Or,it is composed of 4 bytes .

The highest or leftmost bit in the alpha channel is not used which means the alpha channel can onlyhave values from 0 to 127.  You can use the ImageColorAllocate() as with paletted images, but you can also specify the color
directly.

<?php

$im  = ImageCreateTruecolor(300,256);

for($r=0; $r<256; $r++)

{

$col = ImageColorAllocate($im,$r,0,0);

ImageLine($im, 0,$r, 100, $r, $col);

}

for($g=0; $g<256; $g++)

{

$col = ImageColorAllocate($im,0,$g,0);

ImageLine($im, 100,255-$g, 200, 255-$g,
$col);

}

for($b=0; $b<256; $b++)

{

$col = ImageColorAllocate($im,0,0,$b);

ImageLine($im, 200,$b, 300, $b, $col);

}

Header('Content-Type: image/png');ImagePNG($im);

?>

output:

<?

$im = ImageCreateTrueColor(256,60);

for($x=0; $x<256; $x++)

{

ImageLine($im, $x, 0, $x, 19, $x);

ImageLine($im, 255-$x, 20, 255-$x, 39, $x<<8);

ImageLine($im, $x, 40, $x, 59, $x<<16);

}

Header('Content-Type: image/png');ImagePNG($im);

?>

output:

GET:

• When using method=”get” in HTML forms, all variable names and values are displayed in the URL.
• The get method is not suitable for very large variable values.

  POST:

• Information sent from a form with the POST method is invisible to others
  
• no limits on the amount of information to send.

$myImage = ImageCreate(300,300);

Apache’s mod_rewrite document, calls this module as “Swiss Army Knife of URL manipulation!”

mod_rewrite is an Apache module that allows for server-side manipulation of requested URLs. Incoming URLs are checked against a series of rules. The rules contain a regular expression to detect a particular pattern. If the pattern is found in the URL, and the proper conditions are met, the pattern is replaced with a provided substitution string or action. This process continues until there are no more rules left or the process is explicitly told to stop.

Fig: mod_rewrite control flow.

Advantages

1. mod_rewrite can be used to transform long and complex urls into user friendly or short urls.

   For eg. http://myrurl.php/customer.php?name=shan&id=4562&aadr=561

   Above url can be converted to a more user friendly one as,

   http://myurl.php/customer/shan

    

2. Security enhancement.

   Consider the above example a potential hacker can try out different urls to hack into the system by giving different parameters and values passed to customer.php, using mod_rewrite we can prevent such threats.

    

   mod_rewrite can be enabled by uncommenting the line,

   LoadModule rewrite_module modules/mod\_rewrite.so

   in apache configuration file httpd.conf.

If you want to add new items to NSPopUpButton using code in Cocoa Mac, then use the following lines of code

NSString *object1 = @"PHP";

NSString *object2 = @"SQL";

NSString *object3 = @"HTML";

NSString *object4 = @"Objective C";

NSMutableArray *myArray;

myArray= [NSMutableArray arrayWithObjects: object1, object2, object3, object4, nil];

[popUp removeAllItems];

[popUp addItemsWithTitles: myArray];

Here popUp is your NSPopUpButton.

This code will add the items, PHP, SQL, HTML & Objective C to your NSPopUpButton.
