PHP中创建空文件的代码[file_put_contents vs touch]_php技巧

I has passed a small test to check which function is faster to create a new file.

file_put_contents vs touch

for($i = ; $i {
file_put_contents('dir/file'.$i, '');
}
?>

Average time: 0,1145s

for($i = ; $i {
touch('dir/file'.$i);
}
?>

Average time: 0,2322s

所以，file_put_contents比touch快，大约两倍。
