[SOLVED] multiple str_replace??

[daveh33]

$to = str_replace(" ", "+", $to1);

 

This line works fine - but I want it to also replace other characters - I tried to add the below code but it just seems to skip it and nothing is replaced, including the spaces

 

 

 

$to = str_replace(" ", "+", $to1);
$to = str_replace("<", "%3C", $to1);
$to = str_replace("#", "%23", $to1);
$to = str_replace("?", "%3F", $to1);
$to = str_replace(";", "%3B", $to1);
$to = str_replace(":", "%3A", $to1);
$to = str_replace("&", "%26", $to1);
$to = str_replace("$", "%24", $to1);
$to = str_replace("<", "%3C", $to1);
$to = str_replace(">", "%3E", $to1);
$to = str_replace("%", "%25", $to1);
$to = str_replace("{", "%7B", $to1);
$to = str_replace("}", "%7D", $to1);
$to = str_replace("|", "%7C", $to1);
$to = str_replace("@", "%40", $to1);
$to = str_replace("=", "%3D", $to1);

 

What am I doing wrong?

[rajivgonsalves]

I see the variable names

 

say $to1 = "some string";

 

following should be your code

 

$to = str_replace(" ", "+", $to1);
$to = str_replace("<", "%3C", $to);
$to = str_replace("#", "%23", $to);
$to = str_replace("?", "%3F", $to);
$to = str_replace(";", "%3B", $to);
$to = str_replace(":", "%3A", $to);
$to = str_replace("&", "%26", $to);
$to = str_replace("$", "%24", $to);
$to = str_replace("<", "%3C", $to);
$to = str_replace(">", "%3E", $to);
$to = str_replace("%", "%25", $to);
$to = str_replace("{", "%7B", $to);
$to = str_replace("}", "%7D", $to);
$to = str_replace("|", "%7C", $to);
$to = str_replace("@", "%40", $to);
$to = str_replace("=", "%3D", $to);

echo $to;

 

 

 

also you can use urlencode function in php for the same I think

there's htmlspecialchars()

htmlentities()

 

little easier than using mutliple str_replaces

 

 

EDIT

yeah and urlencode...I knew I forgot one

 

beat me to the punch

Well, you have to use use the previous variable and replace occurences within that string/variable.

 

What you currently have is replacing one character, and then when it comes to the next str_replace function, just overwriting it.

You can also use array's with str_replace, I don't know if you noticed that?

 

<?php
$find = array(" ","<","#","?",";",":","&","$","<",">","%","{","}","|","@","=");
$replace = array("+","%3C","%23","%3F","%3B","%3A","%26","%24","%3C","%3E","%25","%7B","%7D","%7C","%40","%3D");
$to = srt_repalce($find, $repalce, $to1);
?>

 

Also, you do know of the function called urlencode?

[daveh33]

many thanks - I got it working using mutliple str_replaces - but seeing the other ways, its not the best way.

 

I haven't used the str_replace function before so didn't know you could use arrays - I tested that and it works the same which a much shorter code.

 

Never used or heard of the urlencode before
