I get this error: Warning: preg_replace() [function.preg-replace]: No ending delimiter '.' found in but I can't figure out why

Here is the code:

foreach( $content as $item )
                {
                    $item = preg_replace( array('.',' '), array('-','-'), strtolower($item));
                    $replace = '<h4 id="'.utf8_decode($item).'">';
                    $phrase = preg_replace('/'.$tag.'/', $replace, $phrase, 1);
                }

Please also tell my WHY it doesn't work

  • @toscho. True. I was creating this within WordPress but I realize now that this indeed has nothing to do with WordPress. My Bad. – Interactive Nov 10 '14 at 8:45

preg_replace expects your first parameter to be a pattern.

Try a simple replace:

$item = str_replace( array('.',' '), array('-','-'), strtolower($item));
