我試圖從數組中返回數據。代碼如下:從子程序返回數組
my %ignorables = map { $_ => 1 } qw([notice mpmstats: rdy bsy rd wr ka log dns cls bsy: in);
open my $error_fh, '<', 'iset_error_log';
sub findLines {
# Iterates over the lines in the file, putting each into $_
while (<$error_fh>) {
# Only worry about the lines containing [notice
if (/\[notice/) {
if (/\brdy\b/){
print "\n";
}
else {
print ",";
}
# Split the line into fields, separated by spaces, skip the %ignorables
my @line = grep { not defined $ignorables{$_} } split /\s+/;
# More cleanup
s/|^\[|notice|[]]//g for @line; # remove [ from [foo
# Output the line
@line = join(",", @line);
s/,,/,/g for @line;
print @line;
}
}
}
&findLines;
當我打印,輸出如下:
Mon,Jun,25,23:24:43,2012,999,1,0,1,0,0,0,0,Mon,Jun,25,23:24:43,2012,1,mod_was_ap22_http.c
Mon,Jun,25,23:32:44,2012,999,1,0,1,0,0,0,0,Mon,Jun,25,23:32:44,2012,1,mod_was_ap22_http.c
Mon,Jun,25,23:33:44,2012,999,1,0,1,0,0,0,0,Mon,Jun,25,23:33:44,2012,1,mod_was_ap22_http.c
Mon,Jun,25,23:45:44,2012,999,1,0,1,0,0,0,0,Mon,Jun,25,23:45:44,2012,1,mod_was_ap22_http.c
如何返回數組子程序之外?
你的意思,而不是打印呢?用巧妙僞裝的[return](http://perldoc.perl.org/functions/return.html)運算符。但你可能意味着別的東西。 – Schwern
