Note that the comparision is case-insensitive. * * Returns FALSE if there are no tokens left. * Does not return empty tokens. * Does not return the "delimiter" command as a token. * * Usage: * The first call to my_strtok() uses the $string and $delimiter arguments. * Every subsequent call to my_strtok() needs no arguments at all, or only * the $delimiter argument to use, as it keeps track of where it is in the * current string. To start over, or to tokenize a new string you simply * call my_strtok() with the both arguments again to initialize it. * The delimiter can be changed by the command "delimiter new_delimiter" in * the $string argument (the command is case-insensitive). * * Example: * $res = my_strtok($query, $delimiter); * while ($res) { * echo "token = $res
"; * $res = my_strtok(); * } * * Author: Andrey Adaikin, IVA Team, * @version $Revision: 1.3 $, $Date: 2005/09/28 $ */ function my_strtok($string = NULL, $delimiter = NULL) { static $str; // lower case $string (equals to strtolower($string)) static $str_original; // stores $string argument static $len; // length of the $string static $curr_pos; // current position in the $string static $match_pos; // position where the $delimiter is a substring of the $string static $delim; // lower case $delimiter (equals to strtolower($delimiter)) WriteLog ( "Enter my_strtok" ); if (NULL === $delimiter) { if (NULL !== $string) { $delim = strtolower($string); $match_pos = -1; } } else { if (!is_string($string) || !is_string($delimiter)) { return FALSE; } $str_original = $string; $str = strtolower($str_original); $len = strlen($str); $curr_pos = 0; $match_pos = -1; $delim = strtolower($delimiter); } if ($curr_pos >= $len) { return FALSE; } if ("" == $delim) { $delim = ";"; $match_pos = -1; } $dlen = strlen($delim); $result = FALSE; for ($i = $curr_pos; $i < $len; ++$i) { if ($match_pos < $i) { $match_pos = strpos($str, $delim, $i); if (FALSE === $match_pos) { $match_pos = $len; } } if ($i == $match_pos) { if ($i != $curr_pos) { $result = trim(substr($str_original, $curr_pos, $i - $curr_pos)); if (strncasecmp($result, 'delimiter', 9) == 0 && (strlen($result) == 9 || FALSE !== strpos(" \t", $result{9}))) { $delim = trim(strtolower(substr($result, 10))); if ("" == $delim) { $delim = ";"; } $match_pos = -1; $result = FALSE; } } $i += $dlen; if ($match_pos < 0) { $dlen = strlen($delim); } $curr_pos = $i--; if ("" === $result) { $result = FALSE; } if (FALSE !== $result) { break; } } else if ($str{$i} == "'") { for ($j = $i+1; $j < $len; ++$j) { if ($str{$j} == "\\") ++$j; else if ($str{$j} == "'") break; } $i = $j; } else if ($str{$i} == "\"") { for ($j = $i+1; $j < $len; ++$j) { if ($str{$j} == "\\") ++$j; else if ($str{$j} == "\"") break; } $i = $j; } else if ($i < $len-1 && $str{$i} == "/" && $str{$i+1} == "*") { $j = $i+2; while ($j) { $j = strpos($str, "*/", $j); if (!$j || $str{$j-1} != "\\") { break; } ++$j; } if (!$j) { break; } $i = $j+1; } else if ($str{$i} == "#") { $j = strpos($str, "\n", $i+1) or strpos($str, "\r", $i+1); if (!$j) { break; } $i = $j; } else if ($i < $len-2 && $str{$i} == "-" && $str{$i+1} == "-" && FALSE !== strpos(" \t", $str{$i+2})) { $j = strpos($str, "\n", $i+3) or strpos($str, "\r", $i+1); if (!$j) { break; } $i = $j; } else if ($str{$i} == "\\") { ++$i; } } if (FALSE === $result && $curr_pos < $len) { $result = trim(substr($str_original, $curr_pos)); if (strncasecmp($result, 'delimiter', 9) == 0 && (strlen($result) == 9 || FALSE !== strpos(" \t", $result{9}))) { $delim = trim(strtolower(substr($result, 10))); if ("" == $delim) { $delim = ";"; } $match_pos = -1; $dlen = strlen($delim); $result = FALSE; } $curr_pos = $len; if ("" === $result) { $result = FALSE; } } WriteLog ( "Exit my_strtok" ); return $result; } /* Processes a set of queries.
