t3lib_sqlparser::parseFieldList ( &$  parseString,
$  stopRegex = '' 
)

Parsing the fields in the "SELECT [$selectFields] FROM" part of a query into an array. The output from this function can be compiled back into a field list with ->compileFieldList() Will detect the keywords "DESC" and "ASC" after the table name; thus is can be used for parsing the more simply ORDER BY and GROUP BY field lists as well!

Parameters:
string The string with fieldnames, eg. "title, uid AS myUid, max(tstamp), count(*)" etc. NOTICE: passed by reference!
string Regular expressing to STOP parsing, eg. '^(FROM)([[:space:]]*)'
Returns:
array If successful parsing, returns an array, otherwise an error string.

t3lib_sqlparser::parseFromTables ( &$  parseString,
$  stopRegex = '' 
)

Parsing the tablenames in the "FROM [$parseString] WHERE" part of a query into an array. The success of this parsing determines if that part of the query is supported by TYPO3.

Parameters:
string list of tables, eg. "pages, tt_content" or "pages A, pages B". NOTICE: passed by reference!
string Regular expressing to STOP parsing, eg. '^(WHERE)([[:space:]]*)'
Returns:
array If successful parsing, returns an array, otherwise an error string.

t3lib_sqlparser::parseWhereClause ( &$  parseString,
$  stopRegex = '' 
)

Parsing the WHERE clause fields in the "WHERE [$parseString] ..." part of a query into a multidimensional array. The success of this parsing determines if that part of the query is supported by TYPO3.

Parameters:
string WHERE clause to parse. NOTICE: passed by reference!
string Regular expressing to STOP parsing, eg. '^(GROUP BY|ORDER BY|LIMIT)([[:space:]]*)'
Returns:
mixed If successful parsing, returns an array, otherwise an error string.

t3lib_sqlparser::parseFieldDef ( &$  parseString,
$  stopRegex = '' 
)

Parsing the WHERE clause fields in the "WHERE [$parseString] ..." part of a query into a multidimensional array. The success of this parsing determines if that part of the query is supported by TYPO3.

Parameters:
string WHERE clause to parse. NOTICE: passed by reference!
string Regular expressing to STOP parsing, eg. '^(GROUP BY|ORDER BY|LIMIT)([[:space:]]*)'
Returns:
mixed If successful parsing, returns an array, otherwise an error string.

t3lib_sqlparser::nextPart ( &$  parseString,
$  regex,
$  trimAll = FALSE 
)

Strips off a part of the parseString and returns the matching part. Helper function for the parsing methods.

Parameters:
string Parse string; if $regex finds anything the value of the first () level will be stripped of the string in the beginning. Further $parseString is left-trimmed (on success). Notice; parsestring is passed by reference.
string Regex to find a matching part in the beginning of the string. Rules: You MUST start the regex with "^" (finding stuff in the beginning of string) and the result of the first parenthesis is what will be returned to you (and stripped of the string). Eg. '^(AND|OR|&&)[[:space:]]+' will return AND, OR or && if found and having one of more whitespaces after it, plus shorten $parseString with that match and any space after (by ltrim())
boolean If set the full match of the regex is stripped of the beginning of the string!
Returns:
string The value of the first parenthesis level of the REGEX.

t3lib_sqlparser::getValue ( &$  parseString,

Parameters:
string The parseString, eg. "(0,1,2,3) ..." or "('asdf','qwer') ..." or "1234 ..." or "'My string value here' ..."
string The comparator used before. If "NOT IN" or "IN" then the value is expected to be a list of values. Otherwise just an integer (un-quoted) or string (quoted)
Returns:
mixed The value (string/integer). Otherwise an array with error message in first key (0)
