如何从外部文件显示/执行PHP？

Question

I have 2 files.

test.zt with the content of a lot of PHP and HTML come.

index.php where I'm including test.zt to display it's contents.

---

What I want to do now is to load test.zt contents into a variable (or something to be able to temporarily edit it). When it's done I want to use str_replace() function to change some text in the test.zt file temporarily. I do not want to overwrite the original test.zt source file.

After that I would like to display the changed file's content to the visitor.

Note: the code is containing PHP code and the page needs to execute that PHP code as well.

I have already tried to open the file with file_get_contents() and then echo out the contents, but it did not execute the PHP side of the content.

Is there any possibility to make this happen?

Answer 1

Basically, you are asking for what eval does. But before you use that, please do some research on what downsides that has.

Instead of using str_replace to “change some text”, you should probably rather just include a normal PHP file, and have that use variables from the main script to output parts of content that need to be dynamic.
