Understanding how to use eval

[george]

How can I save a little PHP code to $Tom, and then evaluate $Tom and save that to a variable as attempted below:?

$Tom = "echo 'blah'"eval($Tom);

When I try and use eval here, I get the following error:

Parse error: syntax error, unexpected $end, expecting ',' or ';'

 

Worse still, I want to save the result of eval to an array element.

 

as for saving the value to an array, I tried

$bob = eval($Tom);and array_push($myarray, $varone, "'".eval($Tom)."'") 

Didn't work.

I am very frustrated with eval.

How can I do what I am trying to do?

That is, save the result of eval to an array element?

 

I did a search on eval, and got a lot of suggestions and saw lots of requests for a replacement function, but the suggestions were what I have seen before, and did not know how to apply, and the requests for a replacement function went unanswered.

 

Thanks

You guys are great.

Where's your semicolon?

Did you check the manual?

The notes describe using a return statement inside the evaluated code to return a value, otherwise eval returns null.
