jquery datepicker with current date and custom date format

I searched the net to find a more simpler solution to set the current date with jQuery UI datepicker but didn't find anything. So here is the solution I used. Mixture of both normal JavaScript and jQuery. You can also check out how to use a custom date format with jQuery UI datepicker.

var currentTime = new Date();
var month = currentTime.getMonth() + 1;
var day = currentTime.getDate();
var year = currentTime.getFullYear();
var d = year + "-" + month + "-" + day;

$('.date-pick').datepicker({ dateFormat: 'yy-mm-dd' }).val(d);

How to get number of characters of a String in php - strlen()

You can use strlen() to easily find the length of an php string.

$str = 'Hello World';
echo strlen($str); // 11

Many new php developers make the mistake of using count() which is used to count elements in an array or properties in an object.
