RE: [PHP] XSLT; XML = PHP code
Good day, To have PHP evaluate string contents as an expression, use eval(). The usual disclaimer comes with this function... be careful.

Ideally, the second string will consist of PHP code. I would like this outputted PHP code to be executed within the same script as the that which performs this transformation. Here is what I am wondering -- will I be able to evaluate the variable containing the new string somehow? In other words, I will have PHP code trapped in a variable, which I will need to have evaluated in order to have the code inside executed. How can I take a variable containing PHP code and have it get executed along with the rest of the script? In other words, $php_code_in_here = 'echo hi there;'; // PHP code in a variable Will this variable just be evaluated by the script as it is parsed?? Forgive me if the answer is staring me in the face, I'm just not seeing it. Thanks, Erik Erik Price Web Developer Temp Media Lab, H.H.

Thanks for the pointer, I have never used this function before. I'm not sure what it means by as with any function that outputs directly to the browser, since in their example it just shows an evaluation of a simple variable assignment (which I'm guessing doesn't get output to the browser). I will have to experiment with this and make sure it works right. The usual disclaimer comes with this function... be careful. (... of what?)

RE: [PHP] XSLT; XML = PHP code
Good day, eval() is a very powerful function. You should be careful that users can't find some way to execute arbitrary code by providing input that your program did not expect. Also, if your string doesn't have the correct syntax, your program will terminate.
