/**
* Searches subject for matches to
* pattern and replaces them with
* replacement.
*
* @param mixed $pattern The pattern to search for. It can be either a string or an array with
* strings.
*
* Several PCRE modifiers
* are also available.
* @param mixed $replacement The string or an array with strings to replace. If this parameter is a
* string and the pattern parameter is an array,
* 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
* otherwise.
*
* If matches are found, the new subject will
* be returned, otherwise subject will be
* returned unchanged.

* @throws PcreException
