I have the following operation which splits a string whenever it encounters an alphabet:
$splitOriginal = preg_split("/[a-zA-Z]/", implode('', array_slice($array, $key)), 2);
I want to extend it in such a way that it splits the string whenever the variable encountered is NOT a number, bracket, plus sign, hyphen, newline or tab.
I have written a regex which can match the above:
preg_match('/^(?=.*[0-9])[- +()0-9\r\n\t]+$/', $value)
But I need to negate it, to match whenever the value being compared is NOT it. Would really appreciate any prompt help I can get.
Thank you.
My Answer:
'/[a-zA-Z]/', $originalString);
To split the string whenever it encounters a character that is not a number, sign, bracket, new line, or tab, you can use the following regex pattern:
php
$splitOriginal = preg_split('/[^0-9\(\)\[\]\{\}\+\-\*\/\n\t]/', $originalString);
This pattern uses the `^` symbol inside the square brackets to match any character that is not a number (`0-9`), opening or closing brackets (`\(\)`, `\[ \]`, `\{ \}`), arithmetic operators (`\+\-\*\/`), new line (`\n`), or tab (`\t`).
