str_replace query

Nixon

Hey all,

Can anybody see why this is nto working. It returns 'http:////' instead of 'http://'. So it is adding extra slashes.

Thanks.

$i=1;

while ($i<=4)

{

$link="link";
$link.=$i;

$replace=str_replace( "\\\", "/", $$link);

$$link=$replace;

echo($$link);

$i++;

}

It is double backslashes because it escapes the last quote if it isn't.

Is there a reason for using variable variables here?

why do you have double $ for link.
when you reference a variable like that, it creates a new variable with the name of the value. (what did I just say?)

$foo = "bar";
$$foo = 1;//create a variable called bar and set it to 1
echo $bar;//outputs a 1

try removing the double $ from $$link.

YEah the variable is right, its a way to use a variable in a while loop without using an array. SO I get the variables $link1, $link2, $link3 and $link4. That bit works fine, its jsut the backslashes being replaced that doesn't work.

What is the value of $link? (the value when in str_replace())

I'll try to reproduce it over here, but I don't have enough data...

$link1 could be http:\www.jack.com\jack.jpg

I now want to convert all those backslashes to forward slashes.

I did the following:

$link = '\\[url]www.jack.com\jack.jpg[/url]';
$replace=str_replace( "\\", "/", $link); 
echo $replace;

And the output:

/www.jack.com/jack.jpg

Now if I use \\www.jack.com\jack.jpg, I get //www.jack.com/jack.jpg.

I'm think you should try the above code to make sure your environment is groovy. And then I'd be a little hesitant about using variable variables. Its made your code rather difficult to read and its hard to tell if str_replace() is getting hung up on it (I didn't have enough info to setup my script with variable variables).
