如何评估变量内容作为PHP代码?

i want to be able to write some code that would contain html and php and then save it in a variable and print it where i need it but i dont know to make the php code inside the variable go through the php compiler before beeing send to the browser.

example:

$var='echo "Hello World"';

echo $var;

output is echo "Hello World".

but i want the output to be Hello World.

Can someone explain me how to do this. thanks.

    You're looking for eval. You should not do this and/or use this unless you really know what you're doing.
