How to concatenate two variables into a string array in php

In PHP, concatenating variables can be implemented using the . operator. The same operation is done to concatenate two variables into a string array. The specific implementation method is as follows:

1. Use the . operator to splice variables:

$var1 = "Hello";
$var2 = "World";
$string = $var1 . " " . $var2; // 将变量拼接为字符串 "Hello World"

2. Use the spliced ​​string explode() function is converted to an array:

$var1 = "Hello";
$var2 = "World";
$string = $var1 . " " . $var2; // 拼接变量为字符串 "Hello World"
$array = explode(" ", $string); // 使用空格分隔符将字符串转换为数组
print_r($array); // 输出结果为["Hello", "World"]

Note: Using the explode() function requires specifying a delimiter, so that the string will be cut according to the delimiter into array items.

In addition to using the explode() function, we can also use the array's [] operator to add variable values ​​to the array:

$var1 = "Hello";
$var2 = "World";
$array = [$var1, $var2]; // 直接使用数组添加变量值
print_r($array); // 输出结果为["Hello", "World"]

Or simpler writing:

$var1 = "Hello";
$var2 = "World";
$array = [$var1, " ", $var2]; // 直接使用数组添加变量值和分隔符
print_r($array); // 输出结果为["Hello", " ", "World"]

In this way, the two variables can be spliced ​​into a string array. According to actual needs, you can choose to use the explode() function or the [] operator of the array to implement it.
