exec() removes trailing newline

[kkmuffme]

Description

The following code:

<?php
echo substr_count( shell_exec( 'echo "hello"; echo "world"' ), PHP_EOL ) . PHP_EOL;
exec( 'echo "hello"; echo "world"', $output );
echo substr_count( implode( PHP_EOL, $output ), PHP_EOL ) . PHP_EOL;

Resulted in this output:

2
1

But I expected this output instead:

2
2

This makes it impossible to know whether the output contained a trailing newline or not in "exec()", however this can be significant. (using shell_exec with explode isn't an alternative, since I generally also need the exit code)

Changing this will probably break tons of code, therefore I guess this should be handled with an additional param perhaps? ($output_exclude_last_trailing_newline = false)

Hi @kkmuffme. What are you suggesting though? That each line in the output array contains the newline? Or that there is an additional empty string in the output array? Tbh, the exec functions are already enough of a mess, it might be best to just use proc_open().
