Preg Replace Question

[tserfer]

Helllo guys

 

Lets say we have 2 strings that we want to replace . For example

 

1) rand(

2) mt_rand(

 

 

(I know that these 2 are functions but lets say that they are strings).

 

If i do:

 

$source = preg_replace( "/rand\(/","NEW");

 

it will Replace the mt_rand as well and it will become

mt_NEW(

 

How can i fix it so that it will replace the whole function and not a part of it?

We are talking about functions in strings

 

 

Hope you understand

Thanks

If there isn't a possible conflict, why not check for rand with a space in front, or not with an underscore in front?

$string = preg_replace('~\brand\(~','new',$string);
