Automatically insert certain special characters at specific locations in a string using php codeigniter

I have a text field to enter a code, and it structure is like 200-00-0000.

When I enter the code in text field I have to generate the hyphen symbol(-) while typing the code at the specific locations as shown in the example code.

I'am using the PHP codeigniter.

Solution

You can use the following code:

<?php
    $data = '200000000';
    echo "".substr($data, 0, 3)."-".substr($data, 3, 3)."-".substr($data,6); // 200-000-0000
?>

check the DEMO here.

In case if you wants to create phone number format then you can use this as follows:

<?php
    $data = '2000000000';
    echo "(".substr($data, 0, 3).") ".substr($data, 3, 3)."-".substr($data,6); // (200) 000-0000
?>

Now; In case if you wants to go with some js code then you can use that as follows:

HTML CODE

</head>
<body>
<input type='text' id='customtext' name='customtext' />
</body>
</html>

JS CODE:

$(window).load(function()
{
   var phones = [{ "mask": "###-###-####"}, { "mask": "(###) ###-##############"}];
    $('#customtext').inputmask({ 
        mask: phones, 
        greedy: false, 
        definitions: { '#': { validator: "[0-9]", cardinality: 1}} });
});
