Question

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?

Answer 1

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).
