fopen, fclose, fwrite....

[pcbrainbuster]

Hello ,

I am a total begginer to PHP and need to know about the functions in the title - fopen, fclose, fwrite (and if there are more then them to) and why does it have f in front of it


And just one more thing

How do set PHP to start itself only when something has been clicked for a example a button ?

How do set PHP to start itself only when something has been clicked for a example a button ?

Don't send the request until the button is clicked.

Because it deals with files. They mimic the C functions.

Other than what's in the PHP docs (which I'm going to optimistically assume you've read), there's not really much more to them. You open a file with fopen(), read/write from it with fread()/fwrite(), then close it with fclose().

Please tell me

Patience is a virtue.

Thanks ,

I understand that now but one thing still haunts me... How would you simply stop PHP i mean in javascript you would do somthing like this -

<button id="id" onclick="asd()">Corck</button>
<script type="thetype">
function asd() {
the scripts
}
</script>

so the function part stops the scriipt from running if the button has not been clicked. but if you do that form thing the php script still has not function thing over it to stop it and how do you even asihn php a function name like asd().

Please give an example with php having an function name asined to it plus a button which is clicked for the php art to activate.

Please can you give me an example of the above ?

You have to understand that PHP does not interact with the DOM, or dynamically change things on the page.

As Twey posted, you would have to send the request to a page to change the data using <form>.

Well may i please have an example ? ,

Plus can javascript read/write/open/close files and can it also run php within it self like this -

<button onclick="asd()">Test</button>
<script>
function asd() {
<?php
echo "You fool !"
?>
}
</script>

Well can it ?
