Situation

I'm struggling trying to minify my index.php file

I've tried

Here is what's in my : index.php

<?php include 'master.php'; ?>

<?php

function htmlmin($buffer)

{
    $search = array( '/\>[^\S ]+/s', '/[^\S ]+\</s', '/(\s)+/s' );
    $replace = array('>','<','\\1');

    if (preg_match("/\<html/i",$buffer) == 1 && preg_match("/\<\/html\>/i", $buffer) == 1) {
        $buffer = preg_replace($search, $replace, $buffer);
    }

    return $buffer;
}

ob_start("htmlmin");

?>

When I do view page source, I still see my html output is not minify. I know that I did something wrong, but I'm not sure what it is.

Did I forget to do something ? Am I on the right track ? Can someone please give me hint ?

I solved this

by using one of the grunt task: grunt-contrib-htmlmin

Install

you may install this plugin with this command:

npm install grunt-contrib-htmlmin --save-dev

Once the plugin has been installed, add this to your Gruntfile

grunt.loadNpmTasks('grunt-contrib-htmlmin');

Setting

htmlmin: {

    dist: {
        files: {
            'index.php': 'index.php',
        }
    }
}

Final File

grunt.initConfig({

        htmlmin: {

            dist: {
                files: {
                    'index.php': 'index.php',
                }
            }
        }

    });


    // Load NPM Tasks
    grunt.loadNpmTasks('grunt-contrib-htmlmin');

    // Default Setting
    grunt.registerTask('default', ['htmlmin']);

};

Execute

Just run grunt on your terminal, the index.php will be minified.

Test/Result

It will not be fun, If I don't show you guys the result. Here is it.
