![]() PS: There is currently a bug in regexr which causes it to show "Error" when first loaded. So matches0 in the firat example is the equivilant of tiele in the second. Here are some javascript demos of similar regular expressions (I'm using N and R instead of \n and \r). Matches0 contains all patterns matched by /w+/. These expressions has been tested on the following OS'es: ubuntu-20.04, ubuntu-18.04, windows-2022, windows-2019, windows-2016, macos-11, macos-10.15 and in the following PHP versions: 8.0, 7.4, 7.3, 7.2, 7.1, 7.0Īnd a successful CI run on a project that runs those tests: This function was DEPRECATED in PHP 5.3.0, and REMOVED in PHP 7.0.0. I got a string: this,is,a','b,test I want to explode it on commas except for commas that are wrapped in double quotes, these should be left unharmed. To remove line breaks (no blank items in the array): $skuList = preg_split('/+/', $_POST) But if you're not using 5. The third parameter however should be set to true. Note that the solution from is very similar, but doesn't handle \n\r. The function strstr() in PHP 5.3 should do this job. ![]() This handles the unusual \n\r as well as the usual \n\r, \n and \r. To preserve line breaks (as blank items in the array): $skuList = preg_split('/\r\n|\n\r|\r|\n/', $_POST) ` It serves a crucial role in string manipulation, allowing developers to convert a string into an array. So please use the solution from to cover all your bases: $skuList = preg_split('/\r\n|\r|\n/', $_POST) What is PHP Explode PHP Explode is an inbuilt function in PHP. So completely parse your data before storing it to remove any system dependent parts.Īndreas' comment made me realize that the 'Best Practice' solution I present here does not apply to the described use-case: the server's EOL (PHP) does not have anything to do with the EOL the browser (any OS) is using, but that (the browser) is where the string is coming from. While using named capture groups provides some declarative benefit, it also bloats the regex pattern and the output array - so I generally dont prefer to use them. This functions returns an array containing the strings formed by splitting the original string. it splits the string wherever the delimiter character occurs. The explode () function splits a string based on a string delimiter, i.e. The new system's constants might be different from the previous system's and the stored data might not work anymore. Your input strings are predictably formatted (in order), so you can write a single regex pattern containing optional capture groups at each of the expected 'units' in the input string. explode () is a built in function in PHP used to split a string in different strings. These constants make your page system independent, but you might run into problems when moving from one system to another when you use the constants with data stored on another system. PHP provides a lot of other very useful constants that you can use to make your code system independent, see this link to find useful and system independent directory constants. As mentioned in the comment to the first answer, the best practice is to use the PHP constant PHP_EOL which represents the current system's EOL ( End Of Line).
