', $ num); // separate integers from decimals $ rl = $ num [1]; // the decimal part value $ j = strlen ($ num [0]) % 3; // Number of digits in the integer $ sl = substr ($ num [0], 0, $ j ); // Obtain the number of less than three digits in the front $ sr = substr ($ num [0], $ j); // Obtain the number of the full three digits in the back $ I = 0; while ($ I <= strlen ($ sr) {$ rvalue = $ rvalue. ','. substr ($ sr, $ I, 3); // three digits are extracted and then merged, separated by commas $ I = $ I + 3;} $ rvalue = $ sl. $ rvalue; $ rvalue = substr ($ rvalue, 0, strlen ($ rvalue)-1); // remove the last comma $ r Value = explode (',', $ rvalue); // break it into an array if ($ rvalue [0] = 0) {array_shift ($ rvalue ); // if the first element is 0, delete the first element} $ rv = $ rvalue [0]; // for ($ I = 1; $ I <count ($ rvalue); $ I ++) {$ rv = $ rv. ','. $ rvalue [$ I];} if (! Empty ($ rl) {$ rvalue = $ rv. '.
