String

String is a PHP topic. In plain words you use it for a short String example in a college portal page. Don’t start with a slogan — start with that picture.

Smallest example: the smallest String example you can type. Type it, run it, and say what you see. If you can do that from memory, you know String.

From the example next to this theory — String — explode splits strings; count works on arrays.

Trap — only saying “String” with no example. Fix that before you talk about advanced PHP.

Viva — what is String? Then show the smallest String example you can type. Then name the trap.

Exam tip

What is String? Show this: the smallest String example you can type. Trap: only saying “String” with no example.

Example

<?php
$s = "prep,pilot,php";
$parts = explode(",", $s);
echo strtoupper($parts[0]) . " count=" . count($parts);

String — explode splits strings; count works on arrays.
