Description Author

This class can validate values from examples with similar format.

It takes an example value, like for instance an e-mail address or a decimal value, and generates a regular expression based on that value considering a common list of delimiter characters.

The generated regular expression can be used to validate other values with similar format without having to specify that regular expression explicitly.

The class can also find all matches of the specified patterns in a given text string.

It can also search for text that is similar to a pattern.

Additional options may set the matching to be case sensitive or not, limit the length of matched text.

One way to validate data that needs to match a given format is to use regular expressions.

Regular expressions are powerful but they are also not easy to understand and often are error prone to create them manually.

This class provides an alternative approach to validate data with regular expressions without the need to manually create them.

It just takes a sample valid values and analyzes them to create regular expressions that match the values based on the position of typical delimiter characters.

There is also MatchAll method which will find all matches by pattern in given string. for example $clas->setPattern("my@gmail.com")->matchAll("Some string with some emails like cool@mail.com or onemore@gmail.com "); will return array of email matches. // Controll methods Method useEachLength(true||false) if set to True will add {1..} Length check for each part of regular Expression Method getRegular() return Generated regualr Expressions; Method caseSens(true||false) set to Generate case sensative regualar expression match or not. ('/i') Method setUseLength(true||false) if set to true add length check at the and of regular expression {10...} so tested string lngth must match to pattern length. Method getSimilar() accpet array of strings Return strings array that are similar to a pattern Method comvertAgains(string ) return array of strings that are transformed against pattern . Method isMatchAll($str) - Return True if one of the Patterns Match in Long text string method SetCorector - > set Arrayt of correction values for comvertAgainst Method .. see Example.php Method setUseNumb(true) - add [0-9] to each Peace of regular expression pattern used when need to match string with numbers Exmple.php - is sets of test that exaplain how it works .
