Manipulating strings for use with capitals is a simple job in PHP as there are 5 functions built in to help you with this task. strtoupper, strtolower, ucwords, ucfirst and lcfirst. In this tutorial I will show you how to use them and examples included.
strtoupper
strtoupper will capitalize all letters in the string given.
This could be used to create an emphasis on a important point such as a title etc.
Now we will move onto strtolower.
strtolower
strtolower is the opposite to strtoupper. strtolower makes all characters in a string to lowercase.
As you can now see all characters are now in the lower case. This can be great if there are lots of capitals in a string may save time rather manually lowering the case.
ucwords
ucwords makes the first letter of every word into a uppercase letter.
ucfirst
ucfirst is similar to the function ucwords but ucfirst only changes the first letter of the first word in the string.
lcfirst
lcfirst does the same function as ucfirst but in reverse so makes the first letter of the first word of the string to lower case.
So that’s it there is several basic functions that are built in to PHP. If you have any questions or feedback please leave a comment.
