t3lib_sqlparser::getValueInQuotes ( &$ parseString,

$ quote

)

Get value in quotes from $parseString. NOTICE: If a query being parsed was prepared for another database than MySQL this function should probably be changed

Parameters:

string String from which to find value in quotes. Notice that $parseString is passed by reference and is shortend by the output of this function.

string The quote used; input either " or '

Returns:
string The value, passed through stripslashes() !

Definition at line 1054 of file class.t3lib_sqlparser.php.

t3lib_sqlparser::nextPart ( &$ parseString,

$ regex,

$ trimAll = FALSE

)

Strips of 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.
