Truncating Strings: Retrieving the First 5 Characters

This question seeks a solution for extracting the first five characters from a given string in PHP. The provided input string is "HelloWordl", and the desired output should yield "Hello".

Single-Byte Strings

For strings with single-byte characters, such as ASCII or ISO 8859, the substr function can be employed:

<code class="php">$result = substr($myStr, 0, 5);</code>

In this snippet, substr starts (0) and retrieves (5) characters from the string $myStr.

Multi-Byte Strings

For strings with multi-byte characters, such as UTF-8 or UTF-16, mb_substr offers a solution:

<code class="php">$result = mb_substr($myStr, 0, 5);</code>

Similar to substr, mb_substr defines 0 as the starting point and 5 as the length of the extracted characters.

By utilizing either substr or mb_substr, depending on the string's encoding, you can effectively retrieve the first five characters from a given string in PHP.
