Join David Powers for an in-depth discussion in this video Dealing with different CSV formats, part of Code Clinic: PHP.
- The functions we've created work well,…but they won't work with every CSV file.…There's no single standard for CSV.…Although CSV is normally assumed…to mean comma-separated values,…it can also mean character-separated values.…In spite of being no single CSV standard,…all CSV files share common features.…Each field is separated by a delimeter character.…The comma is the most common,…but tabs and colons are also widely used as delimeters.…
Whichever character is used,…it must be the same throughout the file.…Fields can be enclosed in quotes.…These are optional unless the field contains line breaks…or the same character as the delimeter.…Double quotes are normally used,…but single quotes are also acceptable.…If a field contains quotes,…the quotes need to be escaped.…This is normally done by proceeding the quotes…with another quotation mark,…but a different escape character is sometimes used.…
The effect of these inconsistencies…is demonstrated by this file cars_table.php.…You can find this file and/or related files…
David introduces challenges and provides an overview of his solutions in PHP. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
