A while back I wrote a little read-eval-print loop that essentially
constituted a very basic php shell:

This has almost always run fine for me with the cgi versions of php 4, and
often proves to be a great help in quickly testing various snippets of code.
However, I just recently tried to use this with PHP 5.1.2, and found that it
doesn't work. Specifically, it seems to wait for input to be typed without
issuing a prompt. Upon entering a line, there's no response, until one
presses ctrl-d. At this point, it throws a parse error:
syntax error, unexpected ')' in phpsh5(23): eval()'d code on line 1
regardless of whether or not there are in fact any unmatched parenths (or any
parenths at all) on the entered line. And it apparently doesn't execute any
of the code at all until one enters exit as a command.
I've tried switching from /dev/stdin to php://stdin, tried adding -f or -a to
the processing options nothing seems to make a difference. I also tried
removing my _readln() function, and simple entering a default expression.
This produces the expected (if repetetive and ultimately practically useless)
results, so I assume it's something in my _readln() function that throws it
off.
Any ideas how to get this to work with PHP 5?
Works for me, PHP 5.1.4. Prehaps you have some kind of output buffering
enabled. Using the -n command line switch will disable your php.ini
which should stop anything like that.
The syntax error you are getting is caused by not entering any input.
Your line 23 becomes:
$returnval = eval(return(););
Return expects some value to be provided, hence the syntax error.
