--EXPECT--
Empty command array:
proc_open(): Argument #1 ($command) must have at least one element
Nul byte in program name:
Command array element 1 contains a null byte
Nul byte in argument:
Command array element 2 contains a null byte
Empty program name:
First element must contain a non-empty program name
Basic usage:
Hello World!
Environment inheritance:
string(5) "ENV_1"
bool(false)
Explicit environment:
bool(false)
string(5) "ENV_2"
Check that arguments are correctly passed through:
array (
0 => 'Simple',
1 => 'White space tab
newline',
2 => '"Quoted"',
3 => 'Qu"ot"ed',
4 => '\\Back\\slash\\',
5 => '\\\\Back\\\\slash\\\\',
6 => '\\"Qu\\"ot\\"ed\\"',
)
