log onto mysql and update column

Please see earlier question:

http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/Q_28319524.html

That works if input is an array and output is echo.



But input table a_messages2_TEST.dateAgo (varchar) is an array and output same column using update.

And there needs to be a mysqli or pdo login to mysql

Note the effect of relying on a date/time string where the year is not specified.  This may or may not produce what you want.  After this has been run, you would want to use phpMyAdmin or a table maintenance script to manually correct the values that could not be converted from the "freeform" to the ISO-8601 standard date.  Once you're satisfied with that process, you can ALTER TABLE to remove the dateAgo column, and rename the validDateAgo column to dateAgo.

"There needs to be" is not a question that we can answer.  This is something that should be a part of your basic library of examples.  You can copy the connection examples from this article.  
http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/PHP_Databases/A_11177-PHP-MySQL-Deprecated-as-of-PHP-5-5-0.html

You can use the connection information over and over.  Usually a programmer would have a common script called at the top of all PHP scripts.  A data base connection might be included in the common script.
output same column using update
I very gently but strongly urge you to NOT do that.  Here is why:
http://en.wikipedia.org/wiki/Mung_%28computer_term%29

There are two good choices:  You can use ALTER TABLE to add a new column and you can update the new column as you convert the datetime strings into the ISO-8601 standard values.  Or you can copy the table and make the updates in the copied table.  I would prefer the first option, because you will be able to use a tool such as phpMyAdmin to examine the rows and make manual corrections if needed.  With the original and standardized datetime values in the same row you will have only one place to look for things that require manual intervention.

If you UPDATE the original rows by overwriting the original columns, you will have lost the original data.  In other words, the process is not reversible and once it is started it must be 100% successful, or you must accept an arbitrarily large failure rate.  Those are not circumstances you want to live with!  See Antipractice #2 and #3.

 You can use ALTER TABLE to add a new column dateAgo_EDIT
so I can compare but I do not know the where statement.

Line 340 destroys the $arr array, so this script will probably be pretty useless.  It was meant as a teaching example to show the design of how you might get some of the data/time values into a usable format.  Obviously it will not work for all of them, but it can reduce the amount of manual work that must be done to correct the contents of the data base.  

Do you have a data base table that has these "strange" date/time values?  If so, you can use a SELECT query to get a results set, then you can use while() to iterate over the results set.  Inside the while loop you can generate the ISO-8601 standard date/time value and you can insert this value into the new column that you've added to the table. This is what is going on in line 267-308.

no these are legacy values

Are the "legacy values" in a data base table?  If so, please post the CREATE TABLE statement and tell us what column contains the legacy values.  If not, please explain where the legacy values are recorded and where you want to put the standardized values.

the only column of that is different is dateAgo
a_messages: dateAgo is datetime (correct)

I checked the code before I decided to run

a_messages is the production table, the column dateAgo is correct datetime and every field has a datetime value

the table a_messages2 (which is not in your code) are the older values which I which to insert into a_messages
dateAgo was varchar and there were many different types of false values

Ray PaseurCommented:
Yes, I understand about dateAgo values.  "Just now" and many of the others are meaningless because there is no date/time context.  This is the sort of thing that has to be handled manually.

Anyway, I hope the concept is clear in the example.  I tested the code and it did what was expected.  Best regards, ~Ray
