PHP String Concatenation Methods Explained

In PHP, you can combine two strings using the “.” operator. For example:

$str1 = "Hello";
$str2 = "World";
$result = $str1 . $str2;

echo $result; // 输出 "HelloWorld"

Another option is to use the concat() function to merge multiple strings together. For example:

$str1 = "Hello";
$str2 = "World";
$result = concat($str1, $str2);

echo $result; // 输出 "HelloWorld"

Please note that the concat() function in PHP is a variable function that can accept any number of parameters to combine them.
