How does the include (include_once) and require (require_once) functions work?
Everytime I step away from PHP, I seem to forget how the include and require work with respect to absolute and relative links.
PHP includes the "include/require files" first then the paths within the include/require are located relative the new location.
If you notice that paragraphs, h1 and other tags have different default margin among browsers, you might want to use the following css code.
* {margin:0px;padding:0px;}
This code removes the additional spaces for all html elements.
OR
If you only want to eliminate the space for selected tags, you will need to use something like the following:
<style>
.no_extra_space
{
margin:0px;
padding:0px;
}
</style>
<p class="no_extra_space">
</p>
use Tablename; select table_name, ENGINE FROM INFORMATION_SCHEMA.TABLES WHERE table_schema=DATABASE();
If you are getting this error : AppleSyncNotifier – System Error.
It is caused by the “MobileMe control panel (http://support.apple.com/kb/DL769)” application that you may not even be aware that was running on your system .
Remove "mobileme control panel" and this should eliminates this error.
What is the real difference between $this and self:: ?
A simple Google search will return several sites that show a definition such as this one:
“Use $this to refer to the current object. Use self to refer to the current class.”
But unless you are a PHP pro, you will need an example to illustrate this definition:
Here is an example to help you out:
class ycsoftware
{
static $stat = "static property";
public $pub='non static property';
public function test_this_self ()
{
print 'Trying to call the static member with this' . $this->stat;
// Nothing will be printed
print 'Trying to call the non static member with this' . $this->pub;
// OK 'non static property' will be printed
print 'Trying to call the static member with self' . self::stat;
// OK
print 'Trying to call the non static member with self' . self::pub
// ERROR
}
}
Use $this for non-static members Use self:: for static members only
