I want to count how many characters matched the beginning when compare two string.
Here is one solution:
<?php
echo '<br>$str1: ', $str1 = 'Hello World';
echo '<br>$str2: ', $str2 = 'Hello WoXld';
for($i2=1; $i2 <= strlen($str1); $i2++):
$char = substr($str1, 0, $i2);
$ok = strcmp(substr($str1, 0, $i2), substr($str2, 0, $i2) );
if($ok):
echo '<h3>' .$ok .' ' .$char .'</h3>';
else:
echo '<h6>' .$ok .' ' .$char .'</h6>';
endif;
endfor;
echo '<br><br><br>';
?>
Output:
Thanks for your help, it working fine and solved my problem…
