The ucwords() function is a built-in function in PHP and is used to convert the first character of every word in a string to upper-case.
Syntax:
string ucwords ( $string, $separator )
Parameter: This function accepts two parameters out of which first is compulsory and second is optional. Both of the parameters are explained below:
- $string: This is the input string of which you want to convert the first character of every word to uppercase.
- $separator: This is an optional parameter. This parameter specifies a character which will be used a separator for the words in the input string. For example, if the separator character is ‘|’ and the input string is “Hello|world” then it means that the string contains two words “Hello” and “world”.
Return value: This function returns a string with the first character of every word in uppercase.
Examples:
Input : $str = "Geeks for neveropen"
ucwords($str)
Output: Geeks For Geeks
Input : $str = "going BACK he SAW THIS"
ucwords($str)
Output: Going BACK He SAW THIS
Below programs illustrate the ucwords() function in PHP:
Program 1:
<?php // original string $str = "Geeks for neveropen"; // string after converting first character // of every word to uppercase $resStr = ucwords($str); print_r($resStr); ?> |
Output:
Geeks For Geeks
Program 2:
<?php // original string $str = "Geeks#for#neveropen #PHP #tutorials"; $separator = '#'; // string after converting first character // of every word to uppercase $resStr = ucwords($str, $separator); print_r($resStr); ?> |
Output:
Geeks#For#Geeks #PHP #Tutorials
Note: You should not use the character ‘$’ as a separator because any name in PHP that starts with $ is considered as a variable name. So, your program may give an error that variable not found.
