__construct()

__construct()

Constructor.

It initializes some fields.

Ends the given string $haystack with the string $needle?

Parameters

string $haystack
string $needle

Returns

boolean —

true, if the parameter $haystack ends with the character sequences $needle, false otherwise

concatUserDefinedVariables()

concatUserDefinedVariables(  $tokens)

Parameters

$tokens

concatComments()

concatComments(  $tokens)

Parameters

$tokens

isBacktick()

isBacktick(  $token)

Parameters

$token

balanceBackticks()

balanceBackticks(  $tokens)

Parameters

$tokens

balanceCharacter()

balanceCharacter(  $tokens,   $idx,   $char)

Parameters

$tokens
$idx
$char

concatColReferences()

concatColReferences(  $tokens)

This function concats some tokens to a column reference.

There are two different cases:

  1. If the current token ends with a dot, we will add the next token
  2. If the next token starts with a dot, we will add it to the previous token

Parameters

$tokens

concatEscapeSequences()

concatEscapeSequences(  $tokens)

Parameters

$tokens

balanceParenthesis()

balanceParenthesis(  $tokens)

Parameters

$tokens
