How to pass form input value to php function

I want to write a php page in which there is a html form. I want to send all input (number for example) of my form to a php function (instead of a javascript function; I make this to hide my javascript function code).
How can I send input value to php function?
Is it possible to call the php function through onclick="function(param1, param2)"?
I know that javascript is a client-side language while php is server-side.
If it is possible, how can I write the return of the function in an input field?
I want to remain in my page.
Is it correct - action="#"?
My code is:
<form action="#" method="get">
Inserisci number1:
<input type="text" name="val1" id="val1"></input>
<?php echo "ciaoooo"; ?>
<br></br>
Inserisci number2:
<input type="text" name="val2" id="val2"></input>
<br></br>
<input type="submit" value="send"></input>
</form>
Help me in the implementation of the simple php function and in the passage of values from input to function!
Thanks!

Make your action empty. You don't need to set the onclick attribute, that's only javascript. When you click your submit button, it will reload your page with input from the form. So write your PHP code at the top of the form.
<?php
if( isset($_GET['submit']) )
{
//be sure to validate and clean your variables
$val1 = htmlentities($_GET['val1']);
$val2 = htmlentities($_GET['val2']);
//then you can use them in a PHP function.
$result = myFunction($val1, $val2);
}
?>
<?php if( isset($result) ) echo $result; //print the result above the form ?>
<form action="" method="get">
Inserisci number1:
<input type="text" name="val1" id="val1"></input>
<?php echo "ciaoooo"; ?>
<br></br>
Inserisci number2:
<input type="text" name="val2" id="val2"></input>

<input type="submit" name="submit" value="send"></input>

You need to look into Ajax; Start here this is the best way to stay on the current page and be able to send inputs to php.
<!DOCTYPE html>
<html>
<head>
<script>
function showHint(str)
{
var xmlhttp;
if (str.length==0)
{
document.getElementById("txtHint").innerHTML="";
return;
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","gethint.php?q="+str,true);
xmlhttp.send();
}
</script>
</head>
<body>
<h3>Start typing a name in the input field below:</h3>
<form action="">
First name: <input type="text" id="txt1" onkeyup="showHint(this.value)" />
</form>
<p>Suggestions: <span id="txtHint"></span></p>
</body>
</html>
This gets the users input on the textbox and opens the webpage gethint.php?q=ja from here the php script can do anything with $_GET['q'] and echo back to the page James, Jason....etc

Remain in my page in the sense that after I click on my button the result is visible in an input field in the same php page.

No, the action should be the name of php file. With on click you may only call JavaScript. And please be aware the hiding your code from the user undermines trust. JS runs on the browser so some trust is needed.

Ok @Christoph but I want to hide some formulas. If I use javascript formulas are visible through web browser.

This is pretty basic, just put in the php file you want to use for processing in the element.
For example
<form action="process.php" method="post">
Then in process.php you would get the form values using $_POST['name of the variable]

You can write your php file to the action attr of form element.
At the php side you can get the form value by $_POST['element_name'].

In his question he says "I want to remain in my page" this to me says Ajax.

Remain in my page in the sense that after I click on my button the result is visible in an input field in the same php page.

You need to look into Ajax; Start here this is the best way to stay on the current page and be able to send inputs to php.
<!DOCTYPE html>
<html>
<head>
<script>
function showHint(str)
{
var xmlhttp;
if (str.length==0)
{
document.getElementById("txtHint").innerHTML="";
return;
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","gethint.php?q="+str,true);
xmlhttp.send();
}
</script>
</head>
<body>
<h3>Start typing a name in the input field below:</h3>
<form action="">
First name: <input type="text" id="txt1" onkeyup="showHint(this.value)" />
</form>
<p>Suggestions: <span id="txtHint"></span></p>
</body>
</html>

No, the action should be the name of php file. With on click you may only call JavaScript. And please be aware the hiding your code from the user undermines trust. JS runs on the browser so some trust is needed.

Ok @Christoph but I want to hide some formulas. If I use javascript formulas are visible through web browser.

This is pretty basic, just put in the php file you want to use for processing in the element.
For example
<form action="process.php" method="post">
Then in process.php you would get the form values using $_POST['name of the variable]

You can write your php file to the action attr of form element.
At the php side you can get the form value by $_POST['element_name'].
