Search $stringreplaced variable for I's and e's

[Love.Oasis]

I currently have code that searches a string for occurrences of different numbers stored inside an array. Upon a digit being found, the number in words is stored in the $stringreplaced variable.

The code then searches the $string variable for occurrences of I's and E's, and if any are founds, displays an appropriate message "x was found". How do I search the $stringreplaced variable instead for I's and E's, or in other words, the text display on line 3:

Orig string: 1234567ie89
I was foundE was found
onetwothreefourfivesixsevenieeightnine - The variable to display this, search all the text in bold on this line for i's and e's.

<?php
$find = array('1', '2', '3', '4', '5', '6', '7', '8', '9');
$replace = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine');

$string = '1234567ie89';
echo 'Orig string: ' .$string . '<br />';


$sarray = str_split($string, 1);
for($i = 0; $i < count($sarray); $i++)
{
    if(strtoupper($sarray[$i]) ==  'E')
        echo 'E was found';
    elseif(strtoupper($sarray[$i]) ==  'I')
        echo 'I was found';
    
    $found = array_search($sarray[$i], $find);
    if($found !== false)
        $sarray[$i] = $replace[$found];
}

$stringreplaced = implode('', $sarray);
echo '<br />' . $stringreplaced; 
?>

I am curious if this is still valid or if you are still looking for an answer to this question as it has been 2+months since your posting. However I will answer this question in an attempt to help not only you but people who might look for this answer in the future.

As I understand it, you are looking to replace 123 with onetwothree and count the occurrences of the letters I and E.

Very well, I would break these up into two different functions so each function may perform it's own action. The first we will call findChar and it will take two variables, the first would be the variable you are searching for and the second will be the string to search.

PHP Code:

function findChar($char, $string) {
  return preg_match(/$char/i, $string);
} 


This function will allow us to reuse it for what ever character you would like to find.

PHP Code:

$string = "mcndhskei1372idj";
if($i = findChar('i', $string)) { 
  echo "I was found $i time(s)<br />\n";
} 


Now you are looking to replace 123 with onetwothree.

PHP Code:

function digit2word($string) {
  $words = array('zero','one','two','three','four','five','six','seven','eight','nine');
  $replaced = '';
  for($i=0; $i<strlen($string); $i++) {
    if(is_numeric($string[$i])) {
      $replaced .= $words[$string[$i]];
    } else {
      $replaced .= $string[$i];
    }
  }
  return $replaced;
}

$string = '867-5309';

echo digit2word($string); 


Using these two functions you could find all the e's or i's in either the string before the replacement or the string after it being replaced with words for each of the digits.

I hope this helps,
