PHP Coding Tips

13 comment(s)

In this post I will show and share to you some of the tips in php that will make your code more cleaner, faster and flexible. This is good for beginner who just starting to learn php. There are many shorcuts to achieve the same result output in php.

Single & Double Quotes

For me, single quotes is more faster than using a double quotes. I will try to explain it in my example.

echo '$var - static text here';

// Output: $var - static text here.


$var2 = "Rob";

echo "$var2 - static text here.";

// Output: Rob - static text here.

As you can see in a single quotes it will not read the variable so it will run fast. Im not telling you not to use double quotes but avoid it as possible.

Arithmetic
Okay, we will use some shortcut here.

$var = $var + 1;

$var2 = $var2 - 1;

Is the same as:


$var ++;
// or
$var2 --;

Control Structure
You can see here the normal if else statement.

    if( $name == 'rob' ) {

        echo 'Rob';

    } else {

        echo 'Not Rob';

    }

The other statement that will do same result.

echo ( $name == 'rob' ) ? 'Rob' : 'Not Rob';

Concatenation
This example is an email message code.

$message = "Greetings $user, nn"

    ."We have contacted you. n"

    ."You have won!n"

    ."and taking all your assets.nn"

    ."Thank you ";

Also, use tabs instead of space in formatting your code. Thats all. Hopefully you learn something in this post :).

dragonheartman: Good stuff! Single quotes are also nice because they allow you to easily output html if you are using php to dynamically do so without having to escape out the quotes.

echo '';

instead of...

echo "";; Monday, July 13th, 2009

Johnny: I don't get the first point. you use static text with the single-quote only.. yeah it will be faster when use it without a var in it then with one. but it doesnt make a difference how you quote that.
You dont even use (your) single-quotes in the last example..
