This function simulates the print_r function in PHP.
Download: Link.
function print_r(obj,pre,child)
{
if(pre === undefined) pre = false;
if(child === undefined) child = 0;
var n = "\n";
var t = " ";
var ts = "";
if(pre) for(var i = 0; i <= child; i++) ts += t;
if(obj.constructor == Array || obj.constructor == Object)
{
if(pre && child == 0)
{
document.write('<pre>'+n);
document.write('Array'+n);
document.write('('+n);
}
else if(pre && child > 0)
{
document.write(ts+'('+n);
}
else
{
document.write('Array (');
}
for(var value in obj)
{
if(obj[value].constructor == Array|| obj[value].constructor == Object)
{
var newChild = child + 1;
if(pre && child == 0)
{
document.write(ts+'['+value+'] => Array'+n);
}
else if(pre && child > 0)
{
document.write(ts+t+'['+value+'] => Array'+n);
newChild++;
}
else
{
document.write(" ["+value+"] => ");
}
print_r(obj[value],pre,newChild);
}
else
{
if(pre && child == 0)
{
document.write(t+'['+value+'] => '+obj[value]+n);
}
else if(pre && child > 0)
{
document.write(ts+t+'['+value+'] => '+obj[value]+n);
}
else
{
document.write(' ['+value+'] => '+obj[value]+' ');
}
}
}
if(pre && child == 0)
{
document.write(') ');
document.write('</pre>');
}
else if(pre && child > 0)
{
document.write(ts+') '+n);
}
else
{
document.write(') ');
}
}
}
Usage:
When you want to nicely format the array with the pre tags, set true after the array parameter in the function.
var array = new Array();
array[0] = 'test0';
array[1] = 'test1';
array[2] = new Array('test2','test3');
array[3] = new Array('test4',new Array('test5','test6'));
array[4] = new Array('test7',new Array('test8',new Array('test9','test10')));
print_r(array);
print_r(array,true);
Output:
Array ( [0] => test0 [1] => test1 [2] => Array ( [0] => test2 [1] => test3 ) [3] ...
Array
(
[0] => test0
[1] => test1
[2] => Array
(
[0] => test2
[1] => test3
)
[3] => Array
(
[0] => test4
[1] => Array
(
[0] => test5
[1] => test6
)
)
[4] => Array
(
[0] => test7
[1] => Array
(
[0] => test8
[1] => Array
(
[0] => test9
[1] => test10
)
)
)
)
This is a simple bookmark function for JavaScript.
function bookmark(title,url)
{
if(title === undefined) title = document.title;
if(url === undefined) url = document.URL;
if(window.sidebar) window.sidebar.addPanel(title,url,''); // Mozilla Firefox Bookmark
else if(window.external) window.external.AddFavorite(url,title); // IE Favorite
else if(window.opera && window.print) return true; // Opera Hotlist
}
Parameters are optional.
The target _blank attribute is not valid when working with XHTML Strict.
The next JavaScript example is a quick workaround to avoid an invalid XHTML page:
New:
document.observe('dom:loaded',function()
{
$$('a[rel="external"]')).each(function(a))
{
a.target = '_blank';
}
});
Old:
document.observe('dom:loaded',function()
{
$$('a').each(function(a)
{
if(a.rel.include('external')) a.target = '_blank';
});
});
When the dom is loaded we search for links. We well loop trough that searching for the value external in the rel attribute, when found we add a target=”_blank” attribute to the link.
So:
<a rel="external" href="somewhereelse">Link</a>
Becomes:
<a rel="external" href="somewhereelse" target="_blank">Link</a>
This workaround is written in JavaScript for prototype users, if you need one without using prototype just drop a comment and i’ll fix you one.
This function simulates the in_array function from PHP.
function in_array(needle, haystack, strict)
{
var found = false, key, strict = !!strict;
for (key in haystack)
{
if ((strict && haystack[key] === needle) || (!strict && haystack[key] == needle))
{
found = true;
break;
}
}
return found;
}
Usage:
var array = new Array('foo', 'bar', 5);
in_array('foo', array); //returns true
in_array('test', array); //returns false
in_array(5, array, true); //returns true
in_array('5', array, true); //returns false while checking strict because 5 is an integer and not a string
This is a function for deleting one single item or an array with items from an array.
function array_delete(&$array, $key_to_be_deleted)
{
$new = array();
if(is_string($key_to_be_deleted))
{
if(!array_key_exists($key_to_be_deleted, $array)) return;
foreach($array as $key => $value) if($key != $key_to_be_deleted) $new[$key] = $value;
$array = $new;
}
if(is_array($key_to_be_deleted)) foreach($key_to_be_deleted as $del) array_delete(&$array, $del);
}
Usage:
array_delete($array, 'item')
In this post i explain how to make a modulair system with clear urls with PHP and .htaccess.
Folder setup:
index.php
.htaccess
/configurations
/modRewrite.php
/modules
/home
/index.php
/test
/index.php
/page.php
Explanation:
Pretty self explaining, all of the configuration files are been put in the configurations folder and modules goes in the modules folder.
.htaccess
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/%{REQUEST_URI} [QSA,L]
Explanation:
RewriteEngine On: Turns on the RewriteEngine.
RewriteCond %{REQUEST_FILENAME} !-f: If the requested file excists, use it.
RewriteCond %{REQUEST_FILENAME} !-d: If the requested folder excists, use it.
RewriteRule ^(.*)$ index.php/%{REQUEST_URI} [QSA,L]: Everything gets redirected to index.php
/configurations/modRewrite.php
if(isset($_SERVER['PATH_INFO']))
{
$parameters = explode('/', $_SERVER['PATH_INFO']);
array_shift($parameters);
}
if(count($parameters) > 1)
{
foreach($parameters as $key => $parameter) define('item'.($key + 1), $parameter);
}
elseif(count($parameters) == 1)
{
define('item1', $parameters[0]);
define('item2', 'index');
}
else
{
define('item1', 'home');
define('item2', 'index');
}
Explanation:
With $_SERVER['PATH_INFO'] we grab everything on the right side of the hostname, example: domainname.nl/test/page -> /test/page.
Next we split that up on the / explode('/', $_SERVER['PATH_INFO']) so we’re getting an array like this: Array ( [0] => [1] => home [2] => page ). We don’t need the first parameter so we remove that one with array_shift($parameters).
After that we’re going to define some constats we can use in our code, these are item1, item2, etc…
index.php
require_once('/configurations/modRewrite.php');
include('/modules/'.item1.'/'.item2.'.php');
Explanation:
Pretty self explaining again, loads the configuration file modRewrite and loads the given module.
Usage:
www.domainname.nl -> /modules/home/index.php
www.domainname.nl/test -> /modules/test/index.php
www.domainname.nl/test/page -> /modules/test/page.php
www.domainname.nl/test/page/7 -> /modules/test/pagie.php the 7 we can use as and id for page numbering for example.
