How to get first 5 characters from string using php

$myStr = "开发者_StackOverflow中文版HelloWordl";

result should be like this

$result = "Hello";

For single-byte strings (e.g. US-ASCII, ISO 8859 family, etc.) use substr and for multi-byte strings (e.g. UTF-8, UTF-16, etc.) use mb_substr:

// singlebyte strings
$result = substr($myStr, 0, 5);
// multibyte strings
$result = mb_substr($myStr, 0, 5);

Use substr():

$result = substr($myStr, 0, 5);

You can use the substr function like this:

echo substr($myStr, 0, 5);

The second argument to substr is from what position what you want to start and third arguments is for how many characters you want to return.

An alternative way to get only one character.

$str = 'abcdefghij';
echo $str{5};

I would particularly not use this, but for the purpose of education. We can use that to answer the question:

$newString = '';
for ($i = 0; $i < 5; $i++) {
    $newString .= $str{$i};
}
echo $newString;

For anyone using that. Bear in mind curly brace syntax for accessing array elements and string offsets is deprecated from PHP 7.4

You can get your result by simply use substr():

Syntax substr(string,start,length)

Example

<?php
$myStr = "HelloWordl";
echo substr($myStr,0,5);
?>

Output :

 Hello
