explode()

The explode() function breaks a string into an array.

explode(separator,string,limit)

In above syntax, "separator" specifies where to break the string, "string" string to split and "limit" specifies the number of array elements to return. Possible values limits are:

1. > 0 : Returns an array with a maximum of limit element(s)
2. < 0 : Returns an array except for the last-limit elements()
3. 0 : Returns an array with one element

Example:

<?php
$str = 'Monday,Tuesday,Wednesday,Thursday,Friday,Saturday,Sunday';

// zero limit
print_r(explode(',',$str,0));
print "<br>";

// positive limit
print_r(explode(',',$str,4));
print "<br>";

// negative limit 
print_r(explode(',',$str,-2));
?>    

Output:

Array ( [0] => Monday,Tuesday,Wednesday, Thursday,Friday,Saturday, Sunday ) 
Array ( [0] => Monday [1] => Tuesday [2] => Wednesday [3] => Thursday,Friday,Saturday, Sunday ) 
Array ( [0] => Monday [1] => Tuesday [2] => Wednesday [3] => Thursday [4] => Friday )
