PHP - Explode function substitution - script with more delimiters of words at once
Separation of words from sentence; checking, correcting and censoring of isolated words; reconstruction of sentence.

//Splitting of text string to an array elements (values) - substitution of explode function - for more delimiters at once

We have corrected sentence as one text string in $what variable.
