PHP - String Functions

Given $text = "abcdefg", which code extracts every second character starting from index 1 using substring extraction in a loop?

Afor ($i = 0; $i < strlen($text); $i += 2) { echo substr($text, $i, 2); }

Bfor ($i = 1; $i < strlen($text); $i += 2) { echo substr($text, $i, 1); }

Cfor ($i = 1; $i <= strlen($text); $i++) { echo substr($text, $i, 1); }

Dfor ($i = 1; $i < strlen($text); $i++) { echo substr($text, $i, 2); }

Step-by-Step Solution

Solution:

Step 1: Loop from index 1 with step 2
Start at 1 to get second character, increment by 2 to get every second character.
Step 2: Extract one character at each position
Use substr with length 1 to get single character at current index.
Final Answer:
for ($i = 1; $i < strlen($text); $i += 2) { echo substr($text, $i, 1); } -> Option B
Quick Check:
Loop with step 2 and substr length 1 extracts every second char [OK]

Quick Trick: Loop with step 2, substr length 1 extracts chars one by one [OK]
