PHP - Capitalise first character of each word expect certain words

I have a batch of strings like so:

tHe iPad hAS gONE ouT of STOCK
PoWER uP YOur iPhone
wHAT moDEL is YOUR aPPLE iPHOne

I want to capitalise the first character of each word and have the remaining characters lowercase - except any references of iPhone or iPad. As in:

By using:

ucwords(strtolower($string));

This can do most of what is needed but obviously also does it on iPadand iPhone:

The Ipad Has Gone Out Of Stock
Power Up Your Iphone
What Model Is Your Apple Iphone

How can I do achieve the below:

The iPad Has Gone Out Of Stock
Power Up Your iPhone
What Model Is Your Apple iPhone
Solution

  • You can use str_replace for this. If you use arrays for the first two arguments, you can define a set of words and replacements:

    echo str_replace(['Ipad', 'Iphone'], ['iPad', 'iPhone'], ucwords(strtolower($string)));

    From the documentation:

    If search and replace are arrays, then str_replace() takes a value from each array and uses them to search and replace on subject.
