PHP str_replace

[Girl]

Hi people. I need help.
I want to use str_replace function a few times.
THe problem is this: for example i have two words: "table" and "house".
I want to replace one word's letters by other one, like:
house
touse
tause
tabse
table

I have letters, when I click on "t", "house"-becomes "touse". But when after it I click "a", it bcomes "hause", not "tause", means it doesn't keep the previous change.
I know I must keep that change somehow, but I don know how.
Please reply if you know.
Thanks

The simplest way of doing this is having a variable with the previous value in it. So if your working with $word then $prevWord would be the previous version of it. Before making any change to $word - simply use $prevWord = $word;. Then each change would actually be something like...

Code: Select all

$word=str_replace("a","o",$prevWord);

The str_replace() function replaces some characters with some other characters in a string.

Syntax:

str_replace(find,replace,string,count)

Where,

find:-Required. Specifies the value to find
replace:- Required. Specifies the value to replace the value in find
string:-Required. Specifies the string to be searched
count:-Optional. A variable that counts the number of replacements
