When renumbering an array using
$arr=array_values($arr); // Renumber array
I realized that a line break is being introduced into one of the array strings, which I don't want.
My string is going from:
Property Type
to Property
Type
In any case I am using:
$newelement = preg_replace("/[^A-Za-z0-9\s\s+]/", " ", $element);
already to remove unwanted characters prior to database insertion, so I tried to change it to:
$newelement = preg_replace("/[^A-Za-z0-9\s\s+'<br>''<br>''/n''/cr']/", " ", $element);
But there is no change, and the ?line feed/line break/carriage return is still there.
Am I doing the preg_replace call correctly?

The line break can be removed from string by using str_replace() function.
The preg_replace() function is an inbuilt function in PHP which is used to perform a regular expression for search and replace the content. Syntax: preg_replace( $pattern, $replacement, $subject, $limit, $count ) Parameters: This function accepts five parameters as mention above and describe below.
str_replace replaces a specific occurrence of a string, for instance "foo" will only match and replace that: "foo". preg_replace will do regular expression matching, for instance "/f. {2}/" will match and replace "foo", but also "fey", "fir", "fox", "f12", etc.
The preg_replace() function returns a string or array of strings where all matches of a pattern or list of patterns found in the input are replaced with substrings. There are three different ways to use this function: 1. One pattern and a replacement string.
That preg looks a bit complicated. And then you have ^ in the beginning as not A-Z... or linefeed. So you don't want to replace linefeed?
How about
$newelement = preg_replace("/[\n\r]/", "", $element);
or
$newelement = preg_replace("/[^A-Za-z ]/", "", $element);
\s also matches linefeed (\n).
