How to add a table to a two-dimensional array in php

PHP is a popular server-side programming language that is widely used in web development. When developing web applications, data tables are a very common way of presentation. Two-dimensional arrays in PHP are very efficient when processing data, and converting two-dimensional arrays into tables is also very easy.

How to convert a two-dimensional array into a table?

In PHP, we can use a for loop to traverse each element in the two-dimensional array and output it to an HTML table. Below we use the following sample data to show how to convert a two-dimensional array into a table:

$data = array( array("Number","Name","Age"), array("1","John","24"), array("2","Smith","28"), array("3","Mike","20") );

The above sample data contains the data of a table, including table headers and data rows. The header includes three columns: "Number", "Name" and "Age", and the data row includes three columns of data: "1", "John", and "24".

First we need to create a table element in the HTML document. The way to create a table element is to add the following tag in the HTML code:

Next we need to add a header to the table. Table headers can be created by reusing a row element inside a table element. Also in the HTML code, we can use the following tags to create a header row element:

In the above tags, thead tag defines the position of the table header, while tr tag defines the header row element . Next we need to traverse the first row of data in the array and output it to the header row element. The PHP code is as follows:

In the above code, we use PHP's foreach loop to traverse the first row of data in the array, and output each element as header column data to the th tag.

Next we need to add data rows to the table. Data rows can be created by reusing multiple row elements inside a table element. Also in the HTML code, we can use the following tags to create a data row element:

In the above tags, the tbody tag defines the position of the data row, while the tr tag defines the data row element. Next we need to iterate through the data rows in the array and output them into the data row element. The PHP code is as follows:

In the above code, we use PHP's for loop to traverse the data rows in the array, and use a foreach loop to traverse each element in each data row, and It is output to the td tag as data column data.

Finally, we insert the table header and data rows into the table element. The PHP code is as follows:

Now we have successfully converted the two-dimensional array into a table, which contains The header and data rows are removed, and each column of data is placed in an HTML td element.

Summary:

In PHP, converting a two-dimensional array into a table is very easy. We just need to iterate through each element in the array and output it to an HTML table. Here, we use a for loop and a foreach loop to traverse the elements in the array and output them to an HTML table.

If you want to use a two-dimensional array to create a data table in your PHP code, then the above method is well worth a try.
