today i will teach you how you can break down a whole sentence into separate words.

lets say i have a string called $string and this is how i declared it:

$string = "breaking down sentence into each word array";

well, if i wanted to break it down, i would have to manually do it like this:

$string1 = "breaking";
$string2 = "down ";
$string3 = "sentence ";
$string4 = "into ";
$string5 = "each ";
$string6 = "word ";
$string7 = "array";

oh, boy, there's gotta be an easier way to do this. i have good news for you, yes you can with a PHP function called explode();

here's and example script:


this would be the output:
OUTPUT:


search:
Split a string by string
Returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by the string delimiter.
explode

(PHP 4, PHP 5)

explode � Split a string by string
Description
array explode ( string $delimiter, string $string [, int $limit] )

Returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by the string delimiter.
Parameters

delimiter

The boundary string.
string

The input string.
limit

If limit is set, the returned array will contain a maximum of limit elements with the last element containing the rest of string.

If the limit parameter is negative, all components except the last -limit are returned.

Although implode() can, for historical reasons, accept its parameters in either order, explode() cannot. You must ensure that the delimiter argument comes before the string argument.
Return Values

If delimiter is an empty string (""), explode() will return FALSE. If delimiter contains a value that is not contained in string, then explode() will return an array containing string.
ChangeLog

Version Description
5.1.0 Support for negative limits was added
4.0.1 The limit parameter was added
