Converting string with html styling ags to title case - php

Question

I'm using this function to convert text to title case:
function strtotitle($title) {
$smallwordsarray = array( 'of','a','the','and','an','or','nor','but','is','if','then','else','when', 'at','from','by','on','off','for','in','to','into','with','it', 'as' );
// Split the string into separate words
$words = explode(' ', $title);
foreach ($words as $key => $word) {
// If this word is the first, or it's not one of our small words, capitalise it
// with ucwords().
if ($key == 0 or !in_array($word, $smallwordsarray))
$words[$key] = ucwords($word);
}
// Join the words back into a string
$newtitle = implode(' ', $words);
return $newtitle;
}
The issue is that if text is bold, italic etc then the function does not work and will not title case the word.
For example: "This is a simple sentence" will be converted to "This is a Simple Sentence". But "This is a simple sentence" will be converted to "This is a simple Sentence".
Any help greatly appreciated.

Answer 1

If you are talking about HTML tags and you want to save it, you can use this implementation:
<?php
/* Your old string */
$string = "<b>asd</b>";
/* Remove html code */
$old = strip_tags($string);
/* Upper case the first letter */
$new = ucfirst($old);
/* Replace old word to new word in $string */
$real = str_replace($old,$new,$string);
/* Here the new string and the old string */
echo $real." ".$string;
?>
So the solution in your code looks like :
function strtotitle($title) {
$smallwordsarray = array( 'of','a','the','and','an','or','nor','but','is','if','then','else','when', 'at','from','by','on','off','for','in','to','into','with','it', 'as' );
// Split the string into separate words
$words = explode(' ', $title);
foreach ($words as $key => $word) {
// If this word is the first, or it's not one of our small words, capitalise it
// with ucwords().
if ($key == 0 or !in_array(strip_tags($word), $smallwordsarray)) {
$old = strip_tags($word);
$new = ucfirst($old);
$words[key] = str_replace($old,$new,$word);
}
}
// Join the words back into a string
$newtitle = implode(' ', $words);
return $newtitle;
}

<?php
function strtotitle($title) {
$smallwordsarray = array( 'of','a','the','and','an','or','nor','but','is','if','then','else','when', 'at','from','by','on','off','for','in','to','into','with','it', 'as' );
$words = $temp = explode(' ', strip_tags($title));
foreach ($temp as $key => $word) {
if ($key == 0 or !in_array($word, $smallwordsarray)) $temp[$key] = ucwords($word);
}
foreach($words as $index => $word) $title = str_replace($word, $temp[$index], $title);
return $title;
}
var_dump(strtotitle('This is a simple sentence'));
var_dump(strtotitle('This is a <b>simple</b> <i>sentence</i>'));

Answer 3

You could use strip_tags this way:
function strtotitle($title) {
$smallwordsarray = array( 'of','a','the','and','an','or','nor','but','is','if','then','else','when', 'at','from','by','on','off','for','in','to','into','with','it', 'as' );
// Remove HTML tags
$titleWithoutTags = strip_tags($title);
// Split the string into separate words
$words = explode(' ', $titleWithoutTags);
foreach ($words as $key => $word) {
// If this word is the first, or it's not one of our small words, capitalise it
// with ucwords().
if ($key == 0 or !in_array($word, $smallwordsarray))
$words[$key] = ucwords($word);
}
// Join the words back into a string
$newtitle = implode(' ', $words);
return $newtitle;
}
