String adding in PHP |
We can add two strings and generate a new string in PHP by using a single dot. This way we can add any number of strings by using " . " ( dot ) in between them. We will learn different types of string addition in PHP. Let us start with simple adding of two strings by using a single dot between them. Here is the example.
$string1="Welcome to plus2net.com";
$string2=" PHP section ";
$string=$string1.$string2;
echo $string;
The out put of the above command will give the full sentence "Welcome to plus2net.com PHP section ". Now let us learn how we can add different strings to a common string variable. Here is the code.
$string= " Hello, ";
$string .=" Welcome to ";
$string .=" plus2net.com ";
echo $string;
The above code will print all the strings one after other forming the complete sentence.
We can merge one string inside another string like this.
$string2=" PHP section ";
$string= "Welcome to plus2net.com $string2";
echo $string;
Here the code will display full string with string2 value added at the end. But this way we can't add function inside a string. Let us try to add one function to display present date inside the welcome message. Here like a string we can't add. The following line won't display today's date along with the string. This is not going to work .
$string= "Welcome to plus2net.com $string2 today on date('m/d/y')”;
We have to modify the above line like this to display current date.
$string= "Welcome to plus2net.com $string2 today on ". date("m/d/y");
echo $string;
