You need a Ajax call to pass the JS value into php variable

JS Code will be (your js file)

var jsString="hello";
$.ajax({
    url: "ajax.php",
    type: "post",
    data: jsString
});

And in ajax.php (your php file) code will be

$phpString = $_POST['data'];     // assign hello to phpString

From: jQuery text truncation (read more style)

Try this:

var title = "This is your title";

var shortText = jQuery.trim(title).substring(0, 10)
    .split(" ").slice(0, -1).join(" ") + "...";

Tested here

And you can also use a plugin:

jQuery Expander Plugin

As a extension of String

String.prototype.trimToLength = function(m) {
  return (this.length > m) 
    ? jQuery.trim(this).substring(0, m).split(" ").slice(0, -1).join(" ") + "..."
    : this;
};

Use as

"This is your title".trimToLength(10);

You can pass the limit as the third parameter of explode that will do the job.

$split = explode('-', 'orange-yellow-red',2);
echo $split[1]; //output yellow-red
