I'm not sure how you could do that as there could be multiple sets of
quotes. If you have:
1 2 "3 4" 5 6 "7 8" 9
How would you write a preg to split only on those *not* encased in quotes?
Here was my solution (posted before for another question):
/**
* does a regular explode, but also accounts for the deliminator to be
within quoted fields
* for example, if called as such:
* splitQuoteFriendly(',', '0,1,2,"3,I am still 3",4');
* it will return:
* array(0 => '0',
* 1 => '1',
* 2 => '2',
* 3 => '"3,I am still 3"',
* 4 => '4');
* @param string deliminator to explode by
* @param string text to explode
* @param string text which surrounds quoted fields (defaults to ")
* @return array array of fields after explode
*/
function explodeQuoteFriendly($delim, $text, $quote = '"') {
$strictFields = explode($delim, $text);
for($sl = 0, $l = 0; $sl < sizeof($strictFields); ++$sl) {
$fields[$l] = $strictFields[$sl];
$numQuotes = 0;
while(fmod($numQuotes += substr_count($strictFields[$sl], $quote),
2) == 1) {
++$sl;
$fields[$l] .= $delim.$strictFields[$sl];
}
++$l;
}
return $fields;
}
