Drupal custom module is not working - php

Question

Here is my custom.info
name = Custom
description = Custom module
core = 7.x
package = Own
and custom.module
<?php
/**
* #file
* An example custom module for selecting, updating and deleting query
*/
/**
* Implementation of hook_block_info()
*/
echo 'Today: \n';
echo date('m/d/Y');
function custom_block_info() {
$block['custom'] = array('info' => t('Custom block'))
return $block;
}
/**
* Implements hook_block_view.
*/
function custom_block_view($delta = '') {
global $user;
$block['content'] = t('Hello #user from IP #host',array(
'#user' => format_username($user),
'#host' => $user->hostname`enter code here`
));
$result = db_select('node','a')
->fields('a', array('title'))
->execute();
foreach($result as $node) {
$items[] = array(
'data' => t($node->title)
);
}
$block['content'] .= theme('item_list', array(
'items' => $items
));
return $block;
}
But this custom module is not displaying data in the sidebar where had i put the block. i have place the echo statement above the code it's not even displaying that echo statement in block can any one tell me how to resolve this????
P.S. I have installed drupal i ve changed nothing in database!

Answer 1

Check if your module is active in the modules list (admin/modules) if so try to put your echo statements in a hook_init like this:
function custom_init(){
echo 'Today: \n';
echo date('m/d/Y');
}
then clear all drupal cache Configuration > Performance > Clear alla caches (admin/config/development/performance)
