QR code is a type of two dimensional barcode which is abbreviated from <\/span><\/span>Quick Response Code<\/span><\/span><\/strong> . <\/span>It is an optical label which contains information about the item. <\/span>It is simply attached to the item. <\/span>It contains black squares which are arranged in a squares grid with white background.<\/span><\/span><\/p>\n

In this blog we will learn how to generate QR code using PHP step by step. <\/span>With the help of simple PHP script you can generate QR code for Text, Phone, URL, Email and SMS.<\/span><\/span>
\n<\/a>\"generate<\/a>
\n<\/a><\/p>\n

In this project you need to create two files:<\/span><\/span><\/p>\n

    \n
  1. qrcode.php<\/span><\/span><\/strong><\/li>\n
  2. index.php<\/span><\/span><\/strong><\/li>\n<\/ol>\n

    \"generate<\/a><\/p>\n

    STEP 1: Define class QrCode in qrcode.php:<\/span><\/span><\/h3>\n

    1. Create a class QrCode. <\/span>In this class, we will define the URL for GOOGLE CHART API and functions to generate the QR code for Text, Phone, URL, Email and SMS.<\/span><\/span><\/p>\n

    <span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">class QrCode {<\/span><\/span>\r\n<span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\n}<\/span><\/span><\/pre>\n
    STEP 2: Define URL of Google chart API in QrCode Class:<\/span><\/span><\/h3>\n
    1. We create variables to store the URL of Google chart API and data which is used to create the QR code.<\/span><\/span><\/p>\n
    <span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">class QrCode {<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\n\/\/URL OF GOOGLE CHART API<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\nprivate $apiUrl = 'https:\/\/chart.apis.google.com\/chart';<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\n\/\/ DATA TO CREATE QR CODE<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\nprivate $data;<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\n}<\/span><\/span><\/pre>\n
    STEP 3: Define Functions to generate QR code of different types in QrCode Class:<\/span><\/span><\/h3>\n
    We have the following types and functions for the same in which we can generate the QR Code:<\/span><\/span><\/p>\n
    1.URL<\/span><\/span><\/strong><\/p>\n
    <span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\/\/ Function which is used to generate the URL type of QR Code.<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\npublic function URL($url = null) {<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\n$this-&gt;data = preg_match(\"#^https?\\:\\\/\\\/#\", $url) ? <\/span><span style=\"vertical-align: inherit;\">$url : \"https:\/\/{$url}\";<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\n}<\/span><\/span><\/pre>\n
    2.Text<\/span><\/span><\/strong><\/p>\n
    <span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\/\/ Function which is used to generate the TEXT type of QR Code.<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\npublic function TEXT($text) {<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\n$this-&gt;data = $text;<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">\r\n}<\/span><\/span><\/pre>\n
    3. EMAIL<\/span><\/span><\/strong><\/p>\n
