How can PHP remove lines with only one bump? And is it even possible? total lines 88 thousand

  • one
    For the described task, the regulars are from cannons on sparrows. In PHP, there is a function that returns the number of characters in a string variable (in common parlance, length). This is more than enough. And if the data array that needs to be cleaned lies in the database table, then the task is even simpler - deleting can (and should be!) Performed by means of a SQL server, and the PHP role will be reduced to sending one simple query on the server. - Akina
