Tips to Speed Up your PHP Applications

Leave a reply

PHP can be quite slow at times. Maybe because we do things we shouldn’t or maybe because we didn’t know the alternatives. So here we are giving you some tips to help you speed up your PHP applications. Enjoy!

Calculate the array size ahead

We usually see codes like this:

$myArray = array(1, 2, 3, 4);
for ($i = 0; $i <= count($myArray); $i++) {
echo $myArray[$i];
}

What’s wrong with the code? Every iteration

$myArray

is recounted — a huge waste of time. Instead, use this:

$myArray = array(1, 2, 3, 4);
$amount = count($myArray);
for ($i = 0; $i <= $amount; $i++) {
echo $myArray[$i];
}

Leave foreach() alone!

Do not use

foreach()

under any circumstances anymore since it has been proven (by several benchmarks) to be extremely slow.

Example of an inefficient piece of code which uses

foreach()

$myArray = array(1, 2, 3, 4);
foreach ($myArray as $value) {
echo $value;
}

Instead, just use regular for: They do exactly the same thing, but this one is much faster!

$myArray = array(1, 2, 3, 4);
$amount = count($myArray);
for ($i = 0; $i <= $amount; $i++) {
echo $myArray[$i];
}

Stay away from Double Quotes as much as possible

Double quotes search for variables within the string which takes up time; and if there’s no variables within the string then it’s pointless to use double quotes. Double quotes (” “) should only be used when needed, otherwise you should use single quotes.

Use echo Efficiently: PHP has to concatenate “Hello” and the value of

$myVar

, and then output it.

echo "Hello" . $myVar;

However, if you use a comma like this: PHP does not have to concatenate the “Hello” and

$myVar

, instead it just outputs both of them.

echo "Hello", $myVar;

PHP Interface and Abstract Explained

Leave a reply

This is going to be very simple explanation between interface and any abstract. We are not going to go as far as “you cannot instantiate an interface or an abstract… blah… any class with an abstract method should be declared as abstract.. etc.”

So, where and when to use interfaces? Normally people will use interface when abstracting becomes a problem.

Let’s say we have the following as example:

<?php
Person
Employee
Employer
Criminal
Rapist
President
Student
?>

Obviously, Employee is a Person, Criminal is a person etc.. Therefore we can have Person as a PARENT class. For person to be abstract, you decide within your application if a person object makes sense… just to not have alien objects.

Now, interfaces are used when, in a group of objects, you have two or more objects that share similar behavior. For instance: President and Employer will

makePolicy()

while Criminal and Rapist will

commitCrime()

. Having said that, normally people would put these methods in their respective classes (but defeating the OO designs). If you put

makePolicy()

in President and Employer class there will be duplication of code. It’s not a good idea as Student or Employee will not normally

makePolicy()

commitCrime()

. In fact, it means Employee object can

makePolicy()

of increasing salary ;) . Therefore in this case we use INTERFACES.

<?php
interface HighOffice {
public function makePolicy();
public function declareEmergency();
}

interface jailable {
public function commitCrime();
public function appeal();
}

abstract class Person {
public function getAge()
{
return "28years";
}
}

public class Employee extend Person {
//do stuff for employee
}

public class Criminal extend Person impliments jailable{
//do stuff for a criminal.

//these must be present.
public function commitCrime()
{

}
public function appeal()
{
}

public class President extend Person impliments HighOffice
{

//do other stuff for President

//then a President should make policies and declare emergency
public function makePolicy()
{
}
public function declareEmergency()
{
}
}

}

?>

Twitter oAuth Stuck in Callback Loop

Leave a reply

Twitter oAuth Stuck in Callback Loop

This problem can sometimes be caused by disabling or refusing to accept cookies. If not, the page cannot access the

$_GET parameters

in the URL then it will keep loooping if you have a check to look for them to see what stage your at in the oAuth process.

$dbc = mysqli_connect

must precede all the

mysqli_real_escape_string calls

to make it work. This is because you need an active mysqli connection to use that function.

Check your code for:

mysqli_real_escape_string

You need to change database connection to mysqli:

http://www.php.net/manual/en/mysqli.construct.php

This function was causing the loop:

// Escape/handler any bad characters passed through request variables.
private static function _escape($values)
{
debug('calling '.__FUNCTION__.'()...');
if(!is_array($values))
{
/* Quote if not integer */
if ( !is_numeric($values) || $values{0} == '0' )
{
$values = stripslashes($values);
// $values = mysqli_real_escape_string(self::$db, $values);

}
}
return $values;
}

Options for escaping:

$values = stripslashes($values);
// $values = mysqli_real_escape_string(self::$db, $values);
// $values = mysql_real_escape_string(self::$db, $values);

//alternative to mysql_real_escape_string
$search = array("\x00", "\n", "\r", "\\", "'", "\"", "\x1a");
$replace = array("\\x00", "\\n", "\\r", "\\\\" ,"\'", "\\\"", "\\\x1a");
$values = str_replace($search, $replace, $value);

I successfully fixed the problem by converting my db to the new mysqli way: Convert old mysql to new mysqli database connections in PHP code.

Full working escape function using mysqli:

// Escape/handler any bad characters passed through request variables.
private static function _escape($values)
{
debug('calling '.__FUNCTION__.'()...');
if(!is_array($values))
{
/* Quote if not integer */
if ( !is_numeric($values) || $values{0} == '0' )
{
if (!self::$db) self::_dbconnect();
$values = stripslashes($values);
self::$db->set_charset("utf8"); //set default character set
$values = mysqli_real_escape_string(self::$db, $values);
debug($values);
}
}
return $values;
}

This can be used with get vars to process

$_GET variables

safely to protect from mysql database injection attacks.

// Processes request vars into local vars dynamically.
private static function _getvars()
{
debug('calling '.__FUNCTION__.'()...');
$vars = array();
//load in GET variables
foreach($_GET as $n => $v)
{
$vars['GET'][$n] = self::_escape($v);
}

//load in POST variables
foreach($_POST as $n => $v)
{
$vars['POST'][$n] = self::_escape($v);
}
return $vars;
}

PHP Blog Engines

PHP Blog Engines

Picking the software that you will need for your blogging is no joke and never been an easy task since it’s not always just about the type of blog engines and content management systems you use. There are many different aspects also to consider when choosing which blogging software to pick like the following (in bold):

First you should know beforehand what features you’ll need? The type of software you might choose is very dependent on the type of blog you are going to run. Some blog engines are more developer and designer friendly, while others are geared more towards new users. It’s a matter of finding software based on the features you need. The size of the software’s community matters too. If it’s larger for one blogging system and much smaller and less active than another; keep in mind though that the more active community is usually a better choice for software, since more active users within development community means more improvements on the code base. The age of the software shows the maturity of the blogging platform. Young projects are more unstable, and are more likely to have bugs. So choose at your own risk.

Then there’s programming language. Many blog platforms run on either PHP or Rails. Apparently this development language is easily implemented on multiple platforms like Linux kernel, MS Windows. It is a preferred scripting language as it is fast, secure and non-compromising on development issues. Another big advantage of PHP development is reduction in attention development and maintenance cost. Since PHP is secure and available with uncompromised quality so it is used for implementation of low cost e-commerce solutions development.

The most loved PHP programming technologies are LAMP (for Linux Kernel) and WAMP (for Windows platform) and these are great platform support for PHP architecture. These architectures are like bundle of different Web development technologies like Apache HTTP Server, MySQL Database, and PHP. PHP engine compiles the PHP code and makes it quick and dynamic. Dedicated PHP developers have the knowledge to work on web development. They come-up with exact solutions for open source Web development with PHP. No wonder why this facility makes the website more flexible and user-friendly!!! You can always find just about any flavor of programming language you prefer though.

Let’s not forget about adding things like forums, a store, or some other feature to your blog. If you ever plan on extending the blog, some blogging software will be more suited to fill that need than others. Just some of most popular blogging systems are: of course WordPress, Drupal, Joomla, Movable Type, ExpressionEngine, Serendipity, etc…
