How to output 99 multiplication table in php
With the continuous development of computer technology, more and more programming languages are developed and used. Among them, PHP, as a scripting language widely used in Web development, has a large user group both at home and abroad. The advantage of PHP language over other languages is that it can be easily mixed with HTML, and the time required to write PHP code is much less than other languages. In this article we will introduce how to use PHP to implement multiplication table table output.
1. What is the multiplication table
The multiplication table is knowledge that primary school students must understand and learn when learning mathematics. In the multiplication table, 1 to 10 are used as row and column factors for multiplication. The column subscripts are usually arranged horizontally and the row subscripts are arranged vertically.
2. Ideas for realizing multiplication table output
The main idea for realizing multiplication table output is to use HTML table tags and loop through the PHP program to output the contents of each row and column. First, we need to determine what should be output in each row and column. Because each item in the table is the product of rows and columns, so when the row subscript is $i and the column subscript is $j, the output content should be is $i*$j.
Next, we need to use the HTML table tag to loop out the contents of each row and column, and finally generate a multiplication table.
3. Implement the specific code
Below, we give a practical example to realize the output of the multiplication table. The code is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>乘法表</title>
</head>
<body>
<table border="1">
<?php
for($i=1;$i<=9;$i++){//外层循环，控制行数
echo "<tr>";//生成表格行开始标签
for($j=1;$j<=$i;$j++){//内层循环，控制列数
echo "<td>".$i."x".$j."=".($i*$j)."</td>";//输出单元格内容
}
echo "</tr>";//生成表格行结束标签
}
?>
</table>
</body>
</html>4. Summary
This article introduces how to use PHP to realize the table output of the multiplication table. As can be seen from the above code, the power of PHP is that it can be easily mixed with HTML code to quickly generate the required page.
In actual development, we can make some improvements and optimizations to the code as needed, such as beautifying tables through CSS styles. No matter how it is optimized and improved, PHP, a simple and powerful language, is undoubtedly one of the indispensable and important tools in web development.
