PREG_SPLIT_NO_EMPTY |
Causes empty substrings to be discarded. |
|
PREG_SPLIT_DELIM_CAPTURE |
Causes any references inside pattern to be captured and returned as part of the function's output. |
|
PREG_SPLIT_OFFSET_CAPTURE |
Causes the position of each substring to be returned as part of the function's output (similar to PREG_OFFSET_CAPTURE in preg_match()). |
Here's an example of how preg_split() can be used:
<?php
$s = 'Ten times he called, and ten times nobody answered';
var_dump (preg_split ('/[ ,]/', $s));
?>
This script causes the string $s to be split whenever either a space or a comma is found, resulting in the following output:
array(10) {
[0]=>
string(3) "Ten"
[1]=>
string(5) "times"
[2]=>
string(2) "he"
[3]=>
string(6) "called"
[4]=>
string(0) ""
[5]=>
string(3) "and"
[6]=>
string(3) "ten"
[7]=>
string(5) "times"
[8]=>
string(6) "nobody"
[9]=>
string(8) "answered"
}
As you can imagine, the explode() function by itself would have been inadequate in this case, because it would have been able to split $s based only on a single character.
