HTML Functions

HTML Functions
These functions generate HTML tags. Here is the list of functions.

Layout functions
string center(string text_to_be_centered)
Centers text with div tag.
e.g. echo center('This is centered text');

string div(string div_text, [style_info or style_class])
Generates div tag with the text given. The second option, $style, is optional. It should specify the style that will be applicable to the div tag.
e.g. echo div('KSF developed by Krishna Srikanth',"text-align:center;");

Appearance Functions
string para(string para_text, [style_info or style_class])
Generates para tag with the style specified
e.g echo para('This is paragraph text.','paraStyleClass');

string heading(int heading_size, string heading_text)
Generates heading tag.
e.g. echo heading(1,'This is heading 1 tag');

Similarly, strong(), bold(), em(), italic(), sub(), sup(), small() functions take single parameter, i.e. the text to be displayed, and return the string with tags prefixed and suffixed.

pre(mixed content)
This can be used both for pre tag, as well as print_r() function. If the content is string, a string with pre tags will be attached. If the content is array, or some other, print_r() functionality is implemented and output is directly echoed. In the second case, pre tags are prefixed and suffixed automatically.
e.g.
echo pre('This is pre tag');
pre($myArray);
