Get the First 2, 3, 4, 5, or 10 Characters from a String in PHP

How to Get the First 2, 3, 4, 5, or 10 Characters from a String in PHP

In PHP, you can use the substr() function to get the first 2, 3, 4, 5, or 10 characters from a string. The substr() function takes two arguments: the first argument is the string, and the second argument is the number of characters to get.

For example, the following code will get the first 2 characters from the string "Hello, world!":

$string = "Hello, world!";
$firstTwoCharacters = substr($string, 0, 2);

echo $firstTwoCharacters; // Output: "He"


The substr() function also has a third argument, which is the offset. The offset specifies the position of the first character to get. For example, the following code will get the first 2 characters from the string "Hello, world!", starting at the third character:

$string = "Hello, world!";
$firstTwoCharacters = substr($string, 3, 2);

echo $firstTwoCharacters; // Output: "lo"

You can also use the substr() function to get the last 2, 3, 4, 5, or 10 characters from a string. To do this, you simply use a negative value for the second argument. For example, the following code will get the last 2 characters from the string "Hello, world!":

$string = "Hello, world!";
$lastTwoCharacters = substr($string, -2);

echo $lastTwoCharacters; // Output: "or"

<?php

// Declare a string variable
$string = "Hello, world!";

// Get the first 2 characters
$firstTwoCharacters = substr($string, 0, 2);

// Get the first 3 characters
$firstThreeCharacters = substr($string, 0, 3);

// Get the first 4 characters
$firstFourCharacters = substr($string, 0, 4);

// Get the first 5 characters
$firstFiveCharacters = substr($string, 0, 5);

// Get the first 10 characters
$firstTenCharacters = substr($string, 0, 10);

// Print the values of the variables
echo $firstTwoCharacters . "<br>";
echo $firstThreeCharacters . "<br>";
echo $firstFourCharacters . "<br>";
echo $firstFiveCharacters . "<br>";
echo $firstTenCharacters . "<br>";
