How do i get the first and last character of a string in php?

What is the simplest way of checking whether the first letter of a string $str is 'a' and the last letter is 'a' too?

Or use substr to get the last character:

if[$str[0] == 'a' && substr[$str,-1] == 'a'] {
    //do whatever you wanted
}

In this article, we will find the last character of a string in PHP. The last character can be found using the following methods.

• Using array[]method
• Using substr[] method

Using array[] Method: In this method, we will find the length of the string, then print the value of [length-1]. For example, if the string is “Akshit” Its length is 6, in zero-indexing, the value of [length-1] is 5 which is the character “t” The length can be found using the PHP strlen[] method.

The strlen[] is a built-in function in PHP which returns the length of a given string. It takes a string as a parameter and returns its length. It calculates the length of the string including all the whitespaces and special characters.

Syntax:

strlen[$string]

Example:

PHP

Output:

Last Character of string is : s

Using substr[] Method: The substr[] is a built-in function in PHP that is used to extract a part of string.

Syntax:

substr[string_name, start_position, string_length_to_cut]

Example: For example, if the string is “Akshit loves GeeksForGeeks”. The last character of the string is “s”. There are 2 ways to reach “s”. From the beginning “s” is at the 25th position. We can find the length of the string, then display “length-1”. This means we want to display part of the string using substr[] method where the starting point is “length-1”.

PHP

Output: From the end, “s” is at 1st position. We can display string from [-1]

Last character of String is : s

From end: “s” is at 1st position

We can display string from “-1”

PHP

Output

Last character of String is: s

NOTE: If you’re using multibyte character encodings like UTF-8, use mb_substr[] instead of substr .
