randomly insert a character when writing to a text file
Hi all
I’m using this code to write to a text file:
[code=php]if (file_exists($file)) {
$fp = fopen($file, “w”) or die(
require(“fileerror.php”)
); }
$numBytes = fwrite($fp, $values) or die(
require(“fileerror.php”)
);
fclose($fp);
please tell me if this could be improved.
what I need to do is randomly insert a character when writing to a text file.
So it looks all jumbled up when loaded at.
e.g.
this is the text file now:
[CODE]
Email Notification: emails sent to you whenever someone replies. Only registered users are eligible.
and this is how I’d like it:
[CODE]
Em%a%il No%%%ti%fi%%c%ati%%%on: e%a%i%ls s%en%t to% y%ou whe%%ne%ver %%som%eo%ne rep%%li%es%%%. On%ly %reg%%is%te%red%%% us%e%rs are e%%%lig%i%ble%.
it doesn’t have to be the % character, it can be anything that will not mess with the php code that generates it.
Can this be done?
Cheers
Chris

$myString = "Email Notification: emails sent to you whenever " .
"someone replies. Only registered users are eligible.";
$newString = "";
for($i=0; $i<strlen($myString); $i++)
{
$newString .= substr($myString, $i, 1);
if(rand(1,10) <= 4) # 40% of the time
{
$newString .= '%'; # change this to desired character
}
}
echo "<p>$newString</p>n";

[B][font=technical][size=3]please note that this will not work.
this line will always insert the first charater.
[font=monospace][size=5] [code=php][/size][/font]
$newString .= substr($myString,0,1);
[/code]
and should be changed to:
[font=monospace][size=5] [code=php][/size][/font]
$newString .= substr($myString,$i,$i+1);
[/code]
[/size][/font] [/B][/QUOTE]

[B]OK... all is great.
I just need to be able to write 'ö' as the desired character.
if I tell it to write 'ö' it doesn't write the character to the text file. just the 'ö/'.
can this be done?
Chris
arrrr! it won't show the code for ö [/B][/QUOTE]
Maybe use
