No programming concept frightens programmers more than regular expressions. For a lot of us, seeing code with regular expressions in it can bring a sense of dread and anxiety. We often have no idea what’s going on or how a regular expression does what it does.

In MacOS Sierra Apple added a Finder keyboard shortcut that makes it possible to quickly show all the hidden files and folders. You just need to do the following:

1. Open the Finder
2. Go to your Macintosh HD folder (access this from Devices in the left column)
3. Hold down CMD-Shift-. (dot)
4. All the hidden files will become visible
5. Hold down CMD-Shift-. (dot) a second time to hide the files again

The easiest way to find your hidden ~/Library/ folder is to do the following:

Therefore, if you have a form with more than one input field, always include a submit button. Specifically an <input> with the type="submit" attribute, or a <button> element should be present. (Note: IE7 has a bug where the typeattribute of a <button> defaults to button instead of submit. Therefore for IE7 compatibility you’ll need <button type="submit">.)

realized there was actually a built in option to turn off the removal of line breaks. No need to go editing the source.The PHP Simple HTML Dom Parser’s load function supports multiple useful parameters:load($str, $lowercase=true, $stripRN=false, $defaultBRText=DEFAULT_BR_TEXT)When calling the load function, simply pass false as the third parameter.$html = new simple_html_dom();$html->load(“stuff”, true, false);If using file_get_html, it’s the ninth parameter.file_get_html($url, $use_include_path = false, $context=null, $offset = -1, $maxLen=-1, $lowercase = true, $forceTagsClosed=true, $target_charset = DEFAULT_TARGET_CHARSET, $stripRN=true, $defaultBRText=DEFAULT_BR_TEXT)Edit: For str_get_html, it’s the fifth parameter (Thanks yitwail)str_get_html($str, $lowercase=true, $forceTagsClosed=true, $target_charset = DEFAULT_TARGET_CHARSET, $stripRN=true, $defaultBRText=DEFAULT_BR_TEXT, $defaultSpanText=DEFAULT_SPAN_TEXT)

Provided that your server receives data in the form of a string which it should if you’re using the jQuery serialize() function. It will be something like: name1=value&name2=value&name3=value You just need to parse the string into an array as follows: $parameters = array(); parse_str($_GET, $parameters); See the following for more information: http://www.php.net/manual/en/function.parse-str.php shareimprove this answer
