Google for Teachers Search Tricks

These search tricks can save you time when
researching online for your next project or just
to find out what time it is across the world, so
start using these right away.
1. Convert units. Whether you want to convert
currency, American and metric units, or any
other unit, try typing in the known unit and
the unknown unit to find your answer (like
"how many teaspoons in a tablespoon" or "10
US dollars in Euros").
2. Do a timeline search. Use "view:timeline"
followed by whatever you are researching to
get a timeline for that topic.
3. Get around blocked sites . If you are having
problems getting around a blocked site, just
type "cache:website address" with website
address being the address of the blocked site
to use Google’s cached copy to get where you
are going.
4. Use a tilde . Using a tilde (~) with a search
term will bring you results with related search
terms.
5. Use the image search. Type in your search
word, then select Images to use the image
search when trying to put a picture to your
term.
6. Get a definition. If you want a definition
without having to track down an online (or a
physical) dictionary, just type
"definition:word" to find the definition of the
word in your results (i.e.: "definition:
serendipity" will track down the definition of
the word "serendipity").
7. Search within a specific website . If you
know you want to look up Babe Ruth in
Wikipedia, type in "site:wikipedia.org Babe
Ruth" to go directly to the Wikipedia page
about Babe Ruth. It works for any site, not just
Wikipedia.
8. Search within a specific kind of site . If you
know you only want results from an
educational site, try "site:edu" or for a
government site, try "site:gov" and your search
term to get results only from sites with those
web addresses.
9. Search for a specific file type . If you know
you want a PDF (or maybe an MP3), just type
in "filetype:pdf" and your search term to find
results that are only in that file type.
10. Calculate with Google. Type in any normal
mathematical expressions to get the answer
immediately. For example, "2*4" will get you
the answer "8.
11. Time. Enter "what time is it" and any location
to find out the local time.
12. Find a term in a URL. This handy trick is
especially useful when searching blogs, where
dates are frequently used in the URL. If you
want to know about a topic for that year only
and not any other year, type "inurl:2009" and
your keyword to find results with your
keyword in URLs with 2009 in them.
13. Use Show Options to refine your search.
Click "Show Options" on your search result
page to have access to tools that will help you
filter and refine your results.
14. Search for a face . If you are looking for a
person and not just their name, type
"&imgtype=face" after the search results to
narrow your results to those with images of
faces

How to prevent SQL injections

Use prepared statements and parameterized
queries. These are SQL statements that are sent
to and parsed by the database server separately
from any parameters. This way it is impossible
for an attacker to inject malicious SQL.
You basically have two options to achieve this:
Using PDO:
$stmt = $pdo->prepare('SELECT * FROM
employees WHERE name = :name');
$stmt->execute(array('name' => $name));
foreach ($stmt as $row) {
// do something with $row
}
Using MySQLi:
$stmt = $dbConnection->prepare('SELECT *
FROM employees WHERE name = ?');
$stmt->bind_param('s', $name);
$stmt->execute();
$result = $stmt->get_result();
while ($row = $result->fetch_assoc()) {
// do something with $row
}
PDO
Note that when using PDO to access a MySQL
database real prepared statements are not used
by default. To fix this you have to disable the
emulation of prepared statements. An example
of creating a connection using PDO is:
$dbConnection = new PDO('mysql:dbna
me=dbtest;host=127.0.0.1;charset=utf8', 'user',
'pass');
$dbConnection->setAttribute(PD
O::ATTR_EMULATE_PREPARES, false);
$dbConnection->setAttribute(PD
O::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
In the above example the error mode isn't
strictly necessary, but it is advised to add it.
This way the script will not stop with a Fatal
Error when something goes wrong. And it gives
the developer the chance to catch any error(s)
which are thrown as PDOExceptions.
What is mandatory however is the first
setAttribute() line, which tells PDO to disable
emulated prepared statements and use real
prepared statements. This makes sure the
statement and the values aren't parsed by PHP
before sending it to the MySQL server (giving a
possible attacker no chance to inject malicious
SQL).
Although you can set the charset in the options
of the constructor, it's important to note that
'older' versions of PHP (< 5.3.6) silently ignored
the charset parameter in the DSN.
Explanation
What happens is that the SQL statement you
pass to prepare is parsed and compiled by the
database server. By specifying parameters
(either a ? or a named parameter like :name in
the example above) you tell the database engine
where you want to filter on. Then when you call
execute, the prepared statement is combined
with the parameter values you specify.
The important thing here is that the parameter
values are combined with the compiled
statement, not an SQL string. SQL injection
works by tricking the script into including
malicious strings when it creates SQL to send to
the database. So by sending the actual SQL
separately from the parameters, you limit the
risk of ending up with something you didn't
intend. Any parameters you send when using a
prepared statement will just be treated as
strings (although the database engine may do
some optimization so parameters may end up as
numbers too, of course). In the example above,
if the $name variable contains 'Sarah'; DELETE
FROM employees the result would simply be a
search for the string "'Sarah'; DELETE FROM
employees", and you will not end up with an
empty table.
Another benefit with using prepared statements
is that if you execute the same statement many
times in the same session it will only be parsed
and compiled once, giving you some speed
gains.
Oh, and since you asked about how to do it for
an insert, here's an example (using PDO):
$preparedStatement = $db->prepare('INSERT
INTO table (column) VALUES (:column)');
$preparedStatement->execute(array('column' =>
$unsafeValue));
