PHP Header Question/Help

    Hey All,

    I am new to PHP coding and had a question on how to execute the following two requests.

    1. I want to have a header.php that will call H2 text from a pool of H2 texts at random.

    For example for:
    <H2>x</H2>
    <H2>y</H2>
    <H2>z</H2>
    <H2>a</H2>
    could be pulled at random when any page is called. What php codes would be able to accomplish these requests? If, endwhile, endif statements?

    2. Additionally I would only like to display a banner image on the static front-page.
    Would something like this work?

    <?php if(!is_home() || !is_front_page()) { ?>
    HEADER BANNER HERE
    <?php } ?>

    Just trying to get an idea of how to tackle this.

    Any help would be extremely appreciate.

    Thanks,
    Dave

    from a pool of H2 texts at random 

    <h2><?php
$input = array(
"x",
"y",
"z",
"a",
"b"
);
$rand_keys = array_rand($input, 1);
echo $input[$rand_keys[0]];
?></h2>

    (not tested) more or less the direct example from:
    http://php.net/manual/en/function.array-rand.php

    (not primarily a WordPress problem – please try to learn php through web search and web tutorials)

    display a banner image on the static front-page 

    <?php if( is_front_page() ) { ?>
HEADER BANNER HERE
<?php } ?>

    alchymyth,

    Thank you kindly for your reply. The header banner worked perfectly.

    I did some searching on the php.net/manual site and am learning quite a bit. However, I had one more question in regards to the array. How do you activate the is_front_page tag to work on FALSE boolean searches. That is, if the page is NOT the front_page I would like the following to return. This code works, but will apply to all pages, even the front_page, where two H2 headers would show up, and I only want one.

    <h2 class="intro">
<?php
$input = array("...because the little things make a difference.", "...because there’s always one more thing to do.",
"...because we listen to your wishes.",
"...because we can make your day perfect.");
$rand_keys = array_rand($input, 2);
echo $input[$rand_keys[0]] . "\n";
?>
</h2>

    I tried the following. It supplies a return of an empty H2 section. as if it is the front_page, when it is not:

    <h2 class="intro">
<?php if( is_front_page(FALSE) ) {
$input = array("...because the little things make a difference.", "...because there’s always one more thing to do.",
"...because we listen to your wishes.",
"...because we can make your day perfect.");
$rand_keys = array_rand($input, 2);
echo $input[$rand_keys[0]] . "\n"; } ?>
</h2>

    Again, please just direct me to a place to look, because I’m not sure of the terminology for which to search.

    Also, is there a php syntax checker?

    Thanks,
    Dave

    if the page is NOT the front_page

    if( !is_front_page() )

    again a fundamantal php problem…

    http://php.net/manual/en/language.operators.logical.php
    http://www.w3schools.com/php/php_operators.asp

    alternative:

    <?php if( is_front_page() ) : ?>
do one thing for the front page
<?php else : ?>
do something else on NOT front pages
<?php endif; ?>

    Thanks again. if( !is_front_page() ) worked like a charm.
