It is very easy to count DOM-Elements within a HTML-file by using jquery. Here is a little example:
Do you need to find out in PHP, when a file was modified? Then you should take a look at the PHP-function filemtime. This function expects a filename as parameter and returns the modification-time of this file.
Here is an example:
< ?php echo filemtime('anyfile.html'); ?>
This PHP-script will output the timestamp of the last modification of the file anyfile.html.
You can also format this by using the date-function:
Normally a HTML-list is displayed vertically, which means that each entry is below the previous entry. But for some reasons you might want to display the list vertically, e.g. for a menubar.
Here is a simple way to do that.
For this example I’ll use the following list:
<ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> </ul>
The result looks like this:
- Item 1
- Item 2
- Item 3
Now, we add some CSS:
In this article I’ll show you, how to output each element of an an assciative array in PHP. First of all, we need an associative array. In this example I’ll use an array with colors as the key and the corresponding HEX-code of this color as the value.
Let’s start! Here is the associative PHP array:
// Our associative array $arrMembers = array( 'Red'=>'ff0000', 'Green'=>'00ff00', 'Blue'=>'0000ff', 'Yellow'=>'ffff00' );
In PHP it’s easy to work with arrays. Just declare someting like this:
<?php $arrX = array("Kay", "Joe","Susan", "Frank"); ?>
Now you can access the values with their index (which starts a 0 for the first item).
<?php // output "Kay" echo $arrX; // output "Susan" echo $arrX; ?>
PHP offers you several ways to get a random value of the array. One simple way is by using the
array_rand() expects the array as a parameter and returns a random index value as integer which then can be used to get the array value.
In a JSF Page you might want to display all entries of a collection as a comma-separated list (or of course another separator). To do that you can use the JSF
If you want to insert a character like & e.g. within a JSF (Java Server Faces) component’s value attribute, you might get an error. To avoid this you must insert a HTML-Entity for the character. Here is a short list for common characters which you might need to replace in your JSF component. Character Entity … Read moreHow to insert special characters like &, < and > into a JSF component
