Search & Replace

[Anon]

Hi,

I am new to PHP and have gotten stuck on an issue. I need to search a string and replace elements of that string using PHP3.

Lets say we have a string named $string
if
$string = abcd

I need to replace "a" with 1, "b" with 2, "c" with 3, "d" with 4 and output that to $new_string

So $new_string would = 1234

If anyone can help I would appreciate it. I have tried several methods but all have failed in one way or another.

For literal strings:

$string="abcd";
$string=str_replace("a","1",$string);

$string is now "1bcd";

There are other ways to replace strings, including strtr() for this specific example as well as the ereg_replace() and preg_replace() functions.

Hi,

Thanks for taking the time to reply. I was able to get single letters replaced, however the problem I am having is getting all the letters replaced and not just one in the string.
