问题描述

以下是Javascript中的代码：

Below is the code in Javascript:

const printNumberStarMatrix = function (row, col) {

    for (let i = 1; i <= row; ++i) {
        let strToPrint = "";
        for (let j = col - i; j >= 1; --j) {
            strToPrint = j + strToPrint;
        }
        while (strToPrint.length < col) {
            strToPrint += "*";
        }
        console.log(strToPrint);
    }
}

我的尝试：



以下是我用php编写的代码：

				$strToPrint = $j + $strToPrint;
			}
	}
	while ($strToPrint < $col) {
		$strToPrint += "*";

echo $strToPrint;
	};
$printNumberStarMatrix(5, 6);
