They are both interpreted languages (scripts), they are both incredibly popular languages running a huge amount of the internet, and they are both some of the simplest languages to start out in.

How do you create a text editor in PHP?
Well it got nothing to do with PHP, you going to need JavaScript to do that :)
Why we use javascript as we have a powerful scripting language php?
First of all, PHP is server side, Javascript is client side. You cannot detect mouse gestures or any clicks with PHP the same way you cannot read a file or modify it or process a form (unless you use AJAX of course). Also, although I love PHP, and it has useful extensions such as the GD library, PHP is not a very good language. Overall we use javascript and PHP because they are used for two completely different things.
What is the difference between single quotes and double quotes?
in programming, single quotes are for characters, and double quotes are for string, but in php, javascript, html, css i don't see any difference between the two.
How can you declare the variable in PHP?
Variables in PHP do not need to be declared like some languages (e.g. JavaScript). This is all that needs to be done to assign a variable: $variable = "Value";
Why is PHP superior to Client side scripting languages such as Javascripting?
Website scripts run in one of two places - the client side or the server side.Client side development is done almost exclusively in JavaScript. This is, in addition to basic HTML and CSS code.So This is the main Reson Javascript is called Client Side scripting language. For Serverside PHP is used,Because PHP is used for development the Dynamically Website. And PHP Need atlist one serve.
What are the similarities between PHP and JavaScript?
there are not many similarities, except the if and else statements, loops, etc... but PHP talks to the server, JavaScript can't. That's why both languages have totally different functions. If you only use basic JavaScript, PHP doesn't differ too much.
How do you connect javascript using php?
Any communication between Javascript code and PHP code needs to be instigated by the Javascript. This is because Javascript is a client side script and PHP is server side. The server can't force data to the browser; it can only reply to requests. The technique of using Javascript on the client side to talk to server side scripts is referred to as AJAX (Asynchronous Javascript And XML). There are several libraries available for simplifying it's usage, and many online tutorials.
How can you pass a JavaScript value into a PHP file?
JavaScript lives in the browser, PHP lives on the server.To pass a value from JavaScript to a PHP page, you can eitherdo an HTML form submituse AJAXIn both cases, the value is sent to the server and you write your PHP to handle it and send a response.The important thing is that the JavaScript value won't be available in PHP when you first generate the page, creating the page and handling the value submitted from the browser are two distinct steps.
Does JavaScript interact with PHP?
Yes, JavaScript and PHP can interact with each other in web development. JavaScript is a client-side scripting language that runs in a user's browser, while PHP is a server-side language that runs on the server. The two languages can communicate with each other through the use of AJAX (Asynchronous JavaScript and XML) requests. JavaScript can make an AJAX request to a PHP script on the server, and the PHP script can process the request and return data back to the JavaScript code. This allows for dynamic, interactive web pages that can update their content without requiring a full page refresh. Overall, JavaScript and PHP are complementary technologies that can work together to create powerful web applications

How can you use a JavaScript variable in the PHP isset function?
You can't actually do that. There is no direct way to make JavaScript code talk to PHP code, as the two languages are interpreted in different locations. The PHP is interpreted by the server, and the JavaScript is interpreted by the client. This means it's easy enough to transfer data from PHP to JavaScript (by generating the JavaScript with the PHP), but not the other way around. If you're simply looking for a way to see if a JavaScript variable is set (from within the JavaScript itself), that can be done with a line like this one: if(myVariable !== undefined){ /* do stuff */} If you actually want to handle it on the PHP side, one way to do so would be to use additional PHP code when that happens. For example: <?php $jsVars = array(); ?> <script type="text/javascript"> var foo = 'bar'; <?php $jsVars['foo'] = 'bar';?> var yub = 'nub'; <?php $jsVars['yub'] = 'nub';?> </script> ... You can then check to see whether a certain variable has been set by seeing if it's in that array: <?php function jsIsset($varname){ global $jsVars; return array_key_exists($varname, $jsVars); } ?> This however, only works when the JavaScript is generated, not when it's interpreted by the client system. For example, imagine you have a variable that is defined by a JavaScript function that is called from an onclick event. By the time that event happens, the page has already been served and the PHP is done executing. If you want the JavaScript to tell the PHP that a variable is defined, you would need to do it through an AJAX request, which I believe is beyond the scope of this question.
How do you use the JavaScript confirm function in PHP?
It has to be done with Javascript. Though you could do something like this:
What programming language is used for webOS applications?

How can you close the iframe in calling page in php and javascript?
Using JavaScript, you can accomplish this by deleting the iframe node from the DOM.
How does form validation differ in JavaScript and PHP?
In JavaScript the validation is done client side, which means it can be easily bypassed by turning JavaScript off in your browser. But with PHP it is server side, which means you can't switch it off, so you can't bypass the validation.
