I'm not sure.....(This isn't homework is it?) I don't get what you mean with the 1-4 thing....but does this help at all ?
You can easily read in a list of characters from a promt as one variable... i.e.
Script is called my_script:
echo "enter a few strings"
read myinput
echo "This is the vairable called myinput that I have: $myinput"
Then when executed you have:
$ my_script
enter a few strings
a qwer 35 asf 45
This is the vairable called myinput that I have: a qwer 35 asf 45
Therefore multiple strings can be passsed into one variable. Basically the spaces are just characters within the string.

SYNOPSIS
bool ctype_print (string $text)
DESCRIPTION
Checks if all of the characters in the provided string, $text, are printable.
PARAMETERS

RETURN VALUES
Returns TRUE if every character in $text will actually create output (including blanks). Returns FALSE if $text contains control charac-
ters or characters that do not have any output or control function at all.
EXAMPLES
Example #1
A ctype_print(3) example
<?php
$strings = array('string1' => "asdf
", 'string2' => 'arf12', 'string3' => 'LKA#@%.54');
foreach ($strings as $name => $testcase) {
if (ctype_print($testcase)) {
echo "The string '$name' consists of all printable characters.
";
} else {
echo "The string '$name' does not consist of all printable characters.
";
}
}
?>
The above example will output:
The string 'string1' does not consist of all printable characters.
The string 'string2' consists of all printable characters.
The string 'string3' consists of all printable characters.

Note
If an integer between -128 and 255 inclusive is provided, it is interpreted as the ASCII value of a single character (negative val-
ues have 256 added in order to allow characters in the Extended ASCII range). Any other integer is interpreted as a string contain-
ing the decimal digits of the integer.
