php - how to find out if csv file fields are tab delimited or comma delimited -


How to find out if the CSV file field tabs are delimited or are delimited with a comma, I need PHP validation. Can anyone help plz thanks in advance?

It is too late to answer this question, but hopefully it will help someone

This is a simple task that will return the delimiter of a file. 

  function getFileDelimiter ($ file, $ checkLines = 2) {$ file = new SplFileObject ($ file); $ Delimiter = array (',', '\ t', ';', '|', ':'); $ Result = array (); $ I = 0; While ($ file-> Valid () & amp; $ i & lt; = $ checkLines) {$ line = $ file-> Fgets (); Forex currency ($ delimiter $ as delimiter) {$ regExp = '/['.$delimiter.']/'; $ Fields = preg_split ($ regExp, $ line); If (count ($ field) & gt; 1) {if (empty! ($ Result [$ delimiter])) {$ result [$ delimiter] ++; } And {$ result [$ delimiter] = 1; }}} $ I ++; } $ Result = array_keys ($ result, maximum ($ result)); Returns $ result [0]; }

Use this function as shown below: 

  $ delimiter = getFileDelimiter ('abc.csv'); // Check the 2 lines to set the delimiter $ delimiter = getFileDelimiter ('abc.csv', 5); // Check the 5 lines to set the delimiter

PS I used preg_split () instead of explosion () because the explosion ('\ t', $ value ) Will not give proper results.

Update: Thanks for @RichardEB, pointing to a bug in code. I have updated it now.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
