DZone Snippets: header code

PHP headers to serve JSON

jeffreybarke (Jeffrey Barke) — Wed, 06 Aug 2008 21:22:20 GMT

The first two headers prevent the browser from caching the response (a problem with IE and GET requests) and the third sets the correct MIME type for JSON.



header('Cache-Control: no-cache, must-revalidate');

header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');

header('Content-type: application/json');

301 redirect with PHP

jeffreybarke (Jeffrey Barke) — Mon, 07 Jul 2008 21:07:31 GMT

For redirects on servers that have .htaccess locked down:



header('HTTP/1.0 301 Moved Permanently');

header('Location: http://new-page.com/');

header('Connection: close');

exit();

PHP redirect code (with correct header)

yentsun (Max korinets) — Wed, 28 May 2008 21:35:25 GMT



header ('HTTP/1.1 301 Moved Permanently');

header('Location: http://domain.com/');

exit;

Resolving a tinyURL to destination URL

mixdev (Arun Vijayan) — Sun, 30 Sep 2007 08:05:34 GMT

Resolving a tinyURL to its original destination URL in a fastest way.



    < ?php



    // request like this http:///tinyurl.php?c=



    $num = $_GET['c'];



    if($fp = fsockopen ("tinyurl.com", 80, $errno, $errstr, 30))

    {

    if ($fp) {

    fputs ($fp, "HEAD /$num HTTP/1.0\r\nHost: tinyurl.com\r\n\r\n");

    while (!feof($fp)) {$headers .= fgets ($fp,128);}

    fclose ($fp);

    }

    $arr1=explode("Location:",$headers);

    $arr=explode("\n",trim($arr1[1]));

    echo trim($arr[0]);

    }

    ?>

How to draw your own table header... (with borders)

aptiva (FjÃ¶lnir Ã?sgeirsson) — Sat, 28 Apr 2007 19:48:47 GMT

// It's a bit hacky at the beginning, but nstableheadercell wasn't exactly making things easy for me



- (void)_drawThemeContents:(NSRect)cellFrame highlighted:(BOOL)highlighted inView:(NSTableHeaderView *)view;

{

	int index = [view columnAtPoint:NSMakePoint(cellFrame.origin.x + 1,cellFrame.origin.y + 1)];

	NSRect headerRect;

	if(index != -1)

		headerRect = [view headerRectOfColumn:index];

	else

		headerRect = NSZeroRect;

	

	[headerImage drawInRect:cellFrame

				   fromRect:NSZeroRect

				  operation:NSCompositeSourceOver

				   fraction:1.0];

	

	[[NSColor colorWithCalibratedRed:207.0/255.0

							   green:207.0/255.0

								blue:207.0/255.0

							   alpha:1.0] set];

	NSRectFill(NSMakeRect(headerRect.origin.x, headerRect.origin.y + 1, headerRect.size.width, headerRect.size.height - 2));

	[headerImage drawInRect:NSMakeRect(headerRect.origin.x, headerRect.origin.y, headerRect.size.width - 1, headerRect.size.height)

Turn CSV with headers into Array of Hashes (in 5 lines or less)

seancribbs (Sean Cribbs) — Wed, 25 Apr 2007 15:10:12 GMT

This assumes you have a CSV file whose first line are headings/labels for the individual columns.



require 'csv'



csv_data = CSV.read 'data.csv'

headers = csv_data.shift.map {|i| i.to_s }

string_data = csv_data.map {|row| row.map {|cell| cell.to_s } }

array_of_hashes = string_data.map {|row| Hash[*headers.zip(row).flatten] }

Cannot modify header information - headers already sent by FIX

dezmarie (Desirae Beberniss) — Sun, 10 Sep 2006 03:54:29 GMT

Buffers output and eliminates problem with spaces/line breaks at the beginning/end of files. Make sure to place ob_start(); before header(); is called.



ob_start();



header("Location: somepage.php"); //Redirect



ob_end_flush();

exit;
