    hello fellas..
    i have this problem replacing a specific word with a variable...for example:

    -------------example.php contains this -------------
    $string = "My name is [Name] what's yours?";
    $NewString = str_replace('[Name]','$myname',$string);
    ----------------------------------------------------

    -------------names.php contains the names-----------
    $myname = "James bond";
    ------------------------------------------------------
    so my final code will look like this:

    in names.php file....
    -------------------------
    include 'example.php';
    $myname = "James bond";
    echo $NewString;
    -------------------------

    now it should output 'My name is James bond what's yours?'
    but when i tested it it shows the variable $myname instead...
    the problem is that i have to replace the word with variable before i put that variable inside the replace function..
    any ideas?

    Hi,

    Try removing the ' ' around the variable $myname.

    $NewString = str_replace('[Name]',$myname,$string);

    Regards,

    Steve

    you didnt understand what im trying 2 do...
    okay lemme give another example:

    I have this emailing script. I wanna do a custom message which contains the [name] tag that will read the variables of emails instead...

    so simply i need to replace this [name] tag with the email variable.. coz from time to time i need 2 update this custom message from the database.. and i dont want to change it from my source code..

    for instance: i have textbox to update this message. this textbox will output my message with the places of possible areas I can replace with varibles..
    so if I insert [name] tag 3 times it should echo the name inside my variable 3 times...did u get the idea?

    Hello,

    if you use stre_replace with '$variable_name' instead of $variable_name as the second parameter, it will take the sting '$variable_name' and not it's content.

    Another way of doing so is by using double quotes like this : echo "Hello $bob";

    It saves one step.

    Have a great day!

    Rather than replacing the String why don't you just put the variable in the output like:

    "My name is $name what's yours?";

    and if you need to use str_replace Steve was correct.

    The problem here is that by the time you set $myname after including example.php, the str_replace() function has already been executed (at that time $myname wasn't set, and thus blank). Try putting the $myname line ABOVE the include of example.php

    why don't you use a small function such as

    function replace_name($myname){
return "My name is ".$myname." what's yours?";
}
