PHP str_replace替换两个单词

Question

My code is below..

echo $type = str_replace(array('q','h','f'),array('Quarter','Half','Full'),$_POST['type']);

here on the above line $_POST['type'] have These 3 values;

1. $_POST type = 'q'
2. $_POST type = 'h'
3. $_POST type = 'f'

I want to replace

• q with Quarter
• h with Half
• f with Full.

My Problem is when $_POST['type']='h',

The result of above code means value of $type came HalFull.

Why this is happening...

Is there any solution for this...?

Thanks

Answer 1

It seems like it is replacing h with Half and then the last f of Half with Full

May be if you can provide a regexp that only replaces if the source string is exactly one character, then it would work.

Try this:

echo $type = preg_replace(array('/^q$/i','/^h$/i','/^f$/i'),array('Quarter','Half','Full'),$_POST['type']);

It works
