通过使用类似方法的Professorfish答案很大程度上相距甚远,但是,嘿……符号和质量在a
使用以下代码获得的文件中gzip压缩:
$symbolsList = ['H', 'He', 'Li', 'Be', 'B', 'C', 'N', 'O', 'F', 'Ne', 'Na', 'Mg', 'Al', 'Si', 'P', 'S', 'Cl', 'Ar', 'K', 'Ca', 'Sc', 'Ti', 'V', 'Cr', 'Mg', 'Fe', 'Co', 'Ni', 'Cu', 'Zn', 'Ga', 'Ge', 'As', 'Se', 'Br', 'Kr', 'Rb', 'Sr', 'Y', 'Zr', 'Nb', 'Mo', 'Tc', 'Ru', 'Rh', 'Pd', 'Ag', 'Cd', 'In', 'Sn', 'Sb', 'Te', 'I', 'Xe', 'Cs', 'Ba', 'La', 'Ce', 'Pr', 'Nd', 'Pm', 'Sm', 'Eu', 'Gd', 'Tb', 'Dy', 'Ho', 'Er', 'Tm', 'Yb', 'Lu', 'Hf', 'Ta', 'W', 'Re', 'Os', 'Ir', 'Pt', 'Au', 'Hg', 'Tl', 'Pb', 'Bi', 'Po', 'At', 'Rn', 'Fr', 'Ra', 'Ac', 'Th', 'Pa', 'U'];
$massesList = [1.008, 4.003, 6.94, 9.012, 10.81, 12.011, 14.007, 15.999, 18.998, 20.18, 22.99, 24.305, 26.982, 28.085, 30.974, 32.06, 35.45, 39.948, 39.098, 40.078, 44.956, 47.867, 50.942, 51.996, 54.938, 55.845, 58.933, 58.6934, 63.546, 65.38, 69.726, 72.630, 74.922, 78.96, 79.904, 83.798, 85.468, 87.62, 88.906, 91.224, 92.906, 95.96, 98, 101.07, 102.906, 106.42, 107.868, 112.411, 114.818, 118.710, 121.760, 127.60, 126.904, 131.293, 132.905, 137.327, 138.905, 140.116, 140.908, 144.242, 145, 150.36, 151.964, 157.25, 158.925, 162.5, 164.93, 167.259, 168.934, 173.054, 174.967, 178.49, 180.948, 183.84, 186.207, 190.23, 192.217, 195.084, 196.967, 200.592, 204.38, 207.2, 208.98, 209, 210, 222, 223, 226, 227, 232.038, 231.036, 238.029];
$fileArrayContent = [$symbolsList, $massesList];
$fileStringContent = json_encode($fileArrayContent);
$file = gzopen('a', 'w9');
gzwrite($file, $fileStringContent);
gzclose($file);
该公式应存储在 $f
变量中:
$a=json_decode(gzfile('a')[0]);$r=@eval('return '.str_replace($a[0],$a[1],preg_replace(['#(?<=(?!\().)(\(|'.implode('|',$a[0]).')#','#\d+#'],['+${1}','*$0'],$f)).';');echo error_get_last()?'Invalid formula':$r;
这是取消评论的版本:
// Recover the data stored in the compressed file
$fileStringContent = gzfile('a')[0];
$fileArrayContent = json_decode($fileStringContent);
$symbolsList = $fileArrayContent[0];
$massesList = $fileArrayContent[1];
$formula = preg_replace('#(?<=(?!\().)(\(|'. implode('|', $symbolsList) .')#', '+${1}', $formula); // Add a "+" before each opening paranthesis and symbol not at the beginning of the string and not preceded by an opening paranthesis
$formula = preg_replace('#\d+#', '*$0', $formula); // Add a "*" before each number
$formula = str_replace($symbolsList, $massesList, $formula); // Replace each symbol with its corresponding mass
$result = @eval('return '. $formula .';'); // Evaluate the value without showing the errors
echo error_get_last() ? 'Invalid formula' : $result; // Print the value, or "Invalid formula" if there was an error
