Run the php code without a file

[zariashasha]

Hello, I wondered if it is possible to run a large code in php without a file?
i.e. let's say there is a link (something like file hosting) on it there is a file s_include.php (open to view code), is it possible to read its code and then run it on php without saving the file?

You can pass the code to the php command like that:

php -r "echo PHP_VERSION;"

yes,i know this method, but what if I have a code of 1000 lines?

It depends on the code, you can also use a pipe stream to execute the php code that was taken from another process, in example:

cat some-file.php | php -r 'eval(file("php://stdin"));'

If you have the link where the code is available then you can replace the file function by file_get_contents

In PHP, you cannot directly execute code without a file. PHP is designed to read and interpret code from files rather than from direct input. However, you can use the eval() function to evaluate PHP code from a string. However, using eval() can introduce security risks and is generally not recommended unless you have complete control and trust over the code being executed. Storing the code in a file and including or requiring that file is a safer and more maintainable approach.
