+ * all patterns will be replaced by that string. If both
+ * pattern and replacement
+ * parameters are arrays, each pattern will be
+ * replaced by the replacement counterpart. If
+ * there are fewer elements in the replacement
+ * array than in the pattern array, any extra
+ * patterns will be replaced by an empty string.
+ *
+ * replacement may contain references of the form
+ * \\n or
+ * $n, with the latter form
+ * being the preferred one. Every such reference will be replaced by the text
+ * captured by the n'th parenthesized pattern.
+ * n can be from 0 to 99, and
+ * \\0 or $0 refers to the text matched
+ * by the whole pattern. Opening parentheses are counted from left to right
+ * (starting from 1) to obtain the number of the capturing subpattern.
+ * To use backslash in replacement, it must be doubled
+ * ("\\\\" PHP string).
+ *
+ * When working with a replacement pattern where a backreference is
+ * immediately followed by another number (i.e.: placing a literal number
+ * immediately after a matched pattern), you cannot use the familiar
+ * \\1 notation for your backreference.
+ * \\11, for example, would confuse
+ * preg_replace since it does not know whether you
+ * want the \\1 backreference followed by a literal
+ * 1, or the \\11 backreference
+ * followed by nothing.  In this case the solution is to use
+ * ${1}1.  This creates an isolated
+ * $1 backreference, leaving the 1
+ * as a literal.
+ *
+ * When using the deprecated e modifier, this function escapes
+ * some characters (namely ', ",
+ * \ and NULL) in the strings that replace the
+ * backreferences. This is done to ensure that no syntax errors arise
+ * from backreference usage with either single or double quotes (e.g.
+ * 'strlen(\'$1\')+strlen("$2")'). Make sure you are
+ * aware of PHP's string
+ * syntax to know exactly how the interpreted string will look.
+ * @param string|array|string[] $subject The string or an array with strings to search and replace.
+ *
+ * If subject is an array, then the search and
+ * replace is performed on every entry of subject,
+ * and the return value is an array as well.
+ * @param int $limit The maximum possible replacements for each pattern in each
+ * subject string. Defaults to
+ * -1 (no limit).
+ * @param int $count If specified, this variable will be filled with the number of
+ * replacements done.
+ * @return string|array|string[] preg_replace returns an array if the
+ * subject parameter is an array, or a string
