str_replace function not working correctly

[littlea5h]

So i am trying to replace spaces and forward slashes in a url with a hyphen. Say we have a website named: www.example.com/car/bmw/porsche where bmw/porsche is one value

 

I can seem to get it to work for a space but having trouble with the forward slash. This is what i have for the space (yes i know the search and replace are at opposite ends but it seems to work and doesn't work if i swap them round)

 

$name = str_replace("-", " ", $request[2]);
$id = $category->find_id_by_name($name);

I tried a number of ways to make it work but it still doesn't seem to want to listen.. these are the ways i have tried but neither work:

 

1.

$name = str_replace("-", array(" ", "/"), $request[2]);
$id = $category->find_id_by_name($name);

2.

$chars = array(" ", "/");
$name = str_replace("-", $chars, $request[2]);
$id = $category->find_id_by_name($name);

Both which produce the error:-  Notice: Array to string conversion

 

3.

$name = str_replace(array("-","//"), " ", $request[2]);
$id = $category->find_id_by_name($name);

In the above code, space works but not the forward slash. Tried changing the forward slash to a single one, single quotes with both one and two slashes but still nothing. I have spent a good couple of hours fiddling around with it but nothing seems to work

<?php

    $str = "abc/def/gh i/x y";

    $new = str_replace(array(' ','/'), '-', $str);


    echo "<pre>$str\n$new</pre>";


    /**** result ********


    abc/def/gh i/x y

    abc-def-gh-i-x-y


    *********************/

?>

<?php
    $str = "abc/def/gh i/x y";
    $new = str_replace(array(' ','/'), '-', $str);
    
    echo "<pre>$str\n$new</pre>";
    
    /**** result ********

    abc/def/gh i/x y
    abc-def-gh-i-x-y

    *********************/
?>

 

 

Thanks a bunch! I tested it for the '/' and it worked like a charm but i needed it for the space aswell, so after fiddling around,i put it inside an array again and I changed it to this:

 $char = array("/"," ");
            $name = str_replace("-", $char, $request[2]);
            $id = $category->find_id_by_name($name);

 

However it doesnt work either, displays that error i stated above so i used the index to get the forward slash and it worked:

e.g

$name = str_replace("-", $char[0], $request[2]);<-- works for forward slash but not space

$name = str_replace("-", $char[1], $request[2]);<-- works for space but not forward slash

I just can't seem to get them to work together!! And from your example you have shown me, $request[2] is not shown but this is needed as this is where the data is, it would really help me out much if my code above was used

Change

 $char = array("/"," ");
            $name = str_replace("-", $char, $request[2])

to

 $char = array("/"," ");
            $name = str_replace($char, "-", $request[2]);

edit : PS what does this give?

 

print_r($request)

Change

 $char = array("/"," ");
            $name = str_replace("-", $char, $request[2])

to

 $char = array("/"," ");
            $name = str_replace($char, "-", $request[2]);

 

Does not work as search and replace works backwards for some reason :s

and print_r($request) ?

[littlea5h]

 $char = array("/"," ");
            $name = str_replace($char, "-", $request[2]);

edit : PS what does this give?

 

print_r($request)

 

With this code...
