how to use str_replace?

guuguu

Ok.. I can write files now...

Now I need to know How to delete/change them..
How do I use str_replace command? I have tried to read PHPmanual but I cant make any sense of it...

Let say that I have txt file called colors.txt and it contains: black

How can I change black to red?
And can I change file name with str_replace?

Could you just give me very simple example please?

ok lets go with this...


$string = "My favorite color is black";

#lets replace black with red now, with the function.
#Then assign it back to $string...
#First option, the string to LOOK for, and the 2nd option is what to replace it with, and the third option is what item to use this on.

$string = str_replace("black", "red", $string);

echo $string;

#Will display: My favorite color is red

Thanks 🙂

But I still got lots of questions....

When writing file, how can I define where I want that file to be?

I am using this code to write files:

<?php
$vastaus = 'Success';
echo $vastaus;
$handle = fopen($tiedosto, 'a');
fwrite($handle, $tuote);
fclose($handle);
?>

Now this is writing everthing in cgi-bin. I want to write diffirent dir that php is.

You would... do this...

$filename = "myDirectory/myfile.php";

Then write to that filename...
