Question

Like I am attempting to use data by using SQL query. After that, the PHP variable contain 123 . Now I want to print 1, 2 and 3 separately on html page.

A string is basically an array of characters, so you can access each char by position easily. You will need to make sure that your value is a string - if it is a number you need to cast it .

<?php
$value = 123;

// Cast our value to a string
$stringValue = (string) $value;

$firstChar = $stringValue[0];
$secondChar = $stringValue[1];
$thirdChar = $stringValue[2];
echo $firstChar.PHP_EOL;
echo $secondChar.PHP_EOL;
echo $thirdChar.PHP_EOL;
