WHAT STEPS WILL REPRODUCE THE PROBLEM?

1. $sql = "SELECT SQL_CALC_FOUND_ROWS SmTable.*, MATCH 
(SmTable.fulltextsearch_keyword) AGAINST ('google googles') AS keyword_score 
FROM SmTable WHERE SmTable.status = 'A' AND (SmTable.country_id = 1 AND 
SmTable.state_id = 10) AND MATCH (SmTable.fulltextsearch_keyword) AGAINST 
('google googles') ORDER BY SmTable.level DESC, keyword_score DESC LIMIT 0,10"

2. $parser = new PHPSQLParser($sql);

WHAT IS THE EXPECTED OUTPUT? WHAT DO YOU SEE INSTEAD?

No output expected.

Instead, it hits line 1242 and prints smth:
if(!is_array($processed)) {
    print_r($processed);   // 1242
    $processed = false;
}

Looks like the parser expects every expression tree to be an array, but the 
code for parsing an "AGAINST" clause will return a single value rather than an 
array if the contents are a single value (on line 1112):

$processed = $list[0];

Changing this to return an array will fix the glitch for your particular code 
sample:

$processed = array($list[0]);

Regarding the print_r: It looks like the author put the print_r in there 
because that is an exceptional case that should normally never occur and 
signals a parsing bug.  But since you have the source code you can just comment 
it out :-)

It looks like there's another debug statement that occurs on lines 165-169 if 
the argument to parse is not a string:

if(!is_string($sql)) {
    echo "SQL:\n";
    print_r($sql);
    exit;
}
