we are going to learn about how to get the first n characters of a string in PHP.
In PHP, strings are the sequence of characters, where the index of the first character is 0, the second character is 1, third character is 3 etc.
Get the first n characters of a string
To get the first n characters of a string, we can use the built-in substr() function in PHP.
Here is an example, that gets the first 3 characters from a following string:
<?phpecho substr("Google", 0, 3);?>Output:
"Goo"
In the example above, we have passed 0, 3 as an arguments to the substr() function. So, it begins the extraction at index 0 and extracts before the 3rd character of a string.
Syntax : substr(string, start, length)
The second argument is start index and third argument is length that means how many characters you need to get from the start index.
