I did a search and did not find a code to leave only the first 4 characters of a string with a smaller size.
I tried this code:
$str = "Códigos";
$str = strtolower($str);
Only I need to leave are the first 4 numbers smaller than the others. What I always find are related to strings .
I think it might solve like this:
$numero = '1234567890';
echo '<small>'.substr($numero, 0, 4).'</small>'.substr($numero, 5);
Using substr I separated the string into 2 parts, one with the first 4% numbers .substr(0, 4) and another with the remaining .substr(5) and added the <small> tag to show in a smaller font.
The result will look like this in the browser:
<small>1234</small>567890
In php you can make a substr() to get the first 4 positions and then use the <font> to place it lower.
Example:
$str = "Gabriel Rodrigues";
function examplo($str) {
return "<font size='1'>" . substr($str, 0, 4) . "</font>" . substr($str, 5);
}
echo examplo($str);
