How to put array elements into php table

In PHP, array is a very commonly used data type that can store multiple values ​​and operate on these values. Arrays are also the most common data structure when processing tabular data.

We can use PHP arrays to store each row of data in the table, and each row of data can be regarded as an array composed of multiple elements. So, how do you put each row of data in the table into an array element?

The following is a sample table data:

| Name  | Age | Gender |
|-------|-----|--------|
| Alice | 20  | Female |
| Bob   | 25  | Male   |
| Charlie | 30 | Male  |

We need to put each row of data into an array element, you can follow the following steps:

1. Create An empty array used to store the array elements of each row of data:

$tableData = array();

2. Loop through each row of data in the table and convert each row of data into array elements:

foreach($rowData as $row) {
    // 将每一行数据转换成数组元素
    $rowArray = array($row['Name'], $row['Age'], $row['Gender']);
    
    // 将数组元素添加到表格数据数组中
    array_push($tableData, $rowArray);
}

In the above code, $rowData is an array containing each row of data. Each row of data is an associative array containing three key-value pairs (Name, Age, Gender). In the loop, we convert each row of data into an array of three elements ($rowArray), and then add this array as an element to the $tableData array.

Now, the $tableData array stores all the data in the table. Each element is an array composed of three values, which can be easily operated. For example, we can use a foreach loop to traverse the entire array and output each row of data:

foreach($tableData as $row) {
    echo $row[0] . " is " . $row[1] . " years old and " . $row[2];
}

In the above code, $row is an array composed of three values, $row[0], $row[1 ], $row[2] represents the first, second and third values. Because we store each row of data in the order of Name, Age, Gender, the first value is Name, the second value is Age, and the third value is Gender.

In summary, the steps to put table data into array elements are as follows:

1. Create an empty array to store the array elements of each row of data.
2. Loop through each row of data in the table, convert each row of data into array elements, and add the array elements to the table data array.
3. Use array operation functions or loop through the array to operate on table data.

The above is how to put table data into array elements in PHP. I hope it will be helpful to everyone.
