I want to show certain data from a MySql table to ExtJs Datagrid.using PHP.
I have searched alot but there are no threads on this topic
I found one but with ExtJs 2

Hope you have gone through examples - http://docs.sencha.com/ext-js/4-0/#!/example/grid/array-grid.html

Below is a small sample hoping that you are looking for the same:

Code:

//Define the model below, map the fields in your JSON coming from the server to the field names in this model

Ext.define('GridModel', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'company', type: 'string'},
        {name: 'price', type: 'string'},
        {name: 'change', type: 'string'},
        {name: 'pctChange', type: 'string'}
    ]
});


//Define the store below, providing it the Model and the URL of PHP file

var storeVar = Ext.create('Ext.data.Store', {
    pageSize: 5,
    model: 'GridModel',
    proxy: {
        type: 'ajax',
        url : 'stores_page_grid.php',
        reader: {
            type: 'json'
        },
        extraParams:{
            action:'pagingTestGrid'
        }
    },
    autoLoad: false
});




// create the Grid

var grid = Ext.create('Ext.grid.Panel', {
    id:'gridId',
    store: storeVar,
    columns: [
        {
            text    : 'Company',
            flex    : 1,
            sortable : false,
            dataIndex: 'company'
        },
        {
            text    : 'Price',
            width    : 75,
            sortable : true,
            dataIndex: 'price'
        },
        {
            text    : 'Change',
            width    : 75,
            sortable : true,
            dataIndex: 'change'
        },
        {
            text    : '% Change',
            width    : 75,
            sortable : true,
            dataIndex: 'pctChange'
        }
    ],
    // paging bar on the bottom
    bbar: Ext.create('Ext.PagingToolbar', {
        store: storeVar,
        displayInfo: true,
        displayMsg: 'Displaying topics {0} - {1} of {2}',
        emptyMsg: "No topics to display"
    }),
    height: 350,
    width: 600,
    title: 'Array Grid',
    renderTo: 'grid-example',
    viewConfig: {
        stripeRows: true
    }
});

You can use PHP script to query data from mySQL and use json_encode to return that data.
