The explode() function

The explode() function is used to split a string into an array.

Syntax: explode(separator,string[,limit]);

separator – the character or characters at which the string should be split.

string – the input string

limit – the maximum number of array elements you allow the string to be split into.

Example inputs:

1.
$str= "This is a simple program";
print_r(explode(" ",$str));

2.
$str= "This is a simple program";
print_r(explode(" ",$str,3));

Carefully note the difference in output between the two examples.

Example outputs:

1.
Array ( [0] => This [1] => is [2] => a [3] => simple [4] => program )

2.
Array ( [0] => This [1] => is [2] => a simple program )
