Php Solutions
Solution 1 - Php
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);
Solution 2 - Php
Use substr():
$result = substr($myStr, 0, 5);
Solution 3 - Php
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.
Solution 4 - Php
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

Solution 5 - Php
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
