Instead of detailing all the possible string functions you can use, we’ll just
give you a brief list. (There’s loads of them!) There’s an example of how to
use each string function, if you click on the links below. Just dip in to them
as and when needed.
chr( ) Convert an ASCII
value to a its equivalent character
ord( ) Find out what
the ASCII value of a character is
echo( ) An alternative
to the print statement
similar_text( ) Tells
you how similar two strings of text are
str_repeat( ) Repeat
a character a specified number of times
str_replace( ) Replace
one string with another
str_word_count( ) Tells
you how many words a string has
strlen( ) Gets the length
of a string
substr( ) Grab a number
of character from a string
Some more examples of string functions can be found on these external
sites:
In the next section, we’ll take a look at PHP Functions: what they are, and
how to create your own.
