I have a function that returns an array. I have another function that just returns the first row, but for some reason, it makes me use an intermediate variable, i.e. this fails:
function f1(/*some args*/) {
return /*an array*/;
}
function f2(/*some args*/) {
return f1(/*some args*/)[0];
}
. . . with:
Parse error: syntax error, unexpected '[' in util.php on line 10
But, this works:
function f1(/*some args*/) {
return /*an array*/;
}
function f2(/*some args*/) {
$temp = f1(/*some args*/);
return $temp[0];
}
I wasn't able to find anything pertinent online (my searches kept getting confused by people with "?", "{", "<", etc.).
I'm self-taught in PHP - is there some reason why I can't do this directly that I've missed?
