How to insert a string in the specified position in PHP
PHP has a built-in substr_replace()
function by using that we can insert a string at the specified
position.
In this below example, we are inserting the mr
after the Hi
in the following string.
$greet= "Hi gowtham";
$newstr = substr_replace($greet," mr", 2, 0);
echo $newstr;
Output:
Hi mr gowtham

is the string you need to insert into the$old_str
.$start
is the position you need to choose to start inserting the string.$length
is how many characters you need to remove from thestart
position.
