A palindrome is a word or phrase that is identical forward o

A palindrome is a word or phrase that is identical forward or backward, such as the word “racecar.” A standard palindrome is similar to a perfect palindrome, except that spaces and punctuation are ignored in a standard palindrome. For example, “Madam, I’m Adam” is a standard palindrome because the characters are identical forward or backward, provided you remove the spaces and punctuation marks.

Write a PHP script that checks a word or a phrase (stored in a string variable) to determine if it is a standard palindrome, a perfect palindrome, or not a palindrome at all. Also, for each letter that the word/phrase contains, count and print the number of times that each consonant and vowel is encountered. Your output will look as follows:

Word/phrase: racecar

Perfect palindrome

Contains consonants:

r - 2

c - 2

Contains vowels:

a - 2

e - 1

Solution

<?php
$word = \"racecar\"; // declare a varibale
$wordRem = preg_replace(\"/[^a-zA-Z]/\", \"\", $word);//word after removing spacces and special characters
$reverse = strrev($word); // reverse the word
$vowels = array(\'a\',\'e\',\'i\',\'o\',\'u\');//all vowels in array
if ($wordRem == $reverse){ // compare if the original word is same as the reverse of the same word
echo \"Word/phrase: \" . $word . \"<br>\";
echo \"Perfect palindrome\" . \"<br>\";
}
else{
echo \"Word/phrase: \" . $word . \"<br>\";
echo \"Not a palindrome\" . \"<br>\";
}
$wordVowel = \"\";
$wordConsonant = \"\";
$len = strlen($wordRem);
for($i=0; $i<$len; $i++){
if(in_array($wordRem[$i], $vowels))
{
$wordVowel .= $wordRem[$i];
}
   else{
       $wordConsonant .= $wordRem[$i];
   }
}
echo \"Contains consonants:\" . \"<br>\";
foreach (count_chars($wordConsonant, 1) as $i => $val) {
echo chr($i) . \"-\" . $val . \"<br>\";
}
echo \"Contains vowels:\" . \"<br>\";
foreach (count_chars($wordVowel, 1) as $i => $val) {
echo chr($i) . \"-\" . $val . \"<br>\";
}
?>
