Php write array to csv file

Adrian Billington, February This makes it generally unsuited to being part of a robust database application. To meet this challenge, we often use a pattern parsing language called Regex which stands for Regular Expressions.

This technique is simple yet extremely effective. The tools that are provided by Oracle export, Data Pump, writeable external tables write data quickly, but in a proprietary format, so for true ASCII flat-files, we have to resort to our own homegrown utilities.

How to read Excel files with PHP

The buffer will only be null on the very first entry to the loop, so we make it the very last test; Lines For this reason, the example is omitted from this article, but is included in the accompanying download.

A dump utility would usually accept the delimiter as a parameter and concatenate a record piecemeal especially if using dynamic SQL ; Lines They would allow fields to be encased in double quotes as a signature that the value inside this field should be read literally including commas from the first double quote to the ending double quote.

FFLUSH procedures, but a test with our sample data took over 85 seconds, which is considerably slower than our baseline.

We will see that with simple techniques we can achieve significant performance gains for our data unloads.

When all source data has been added to the CLOB, we will write it to a flat-file in a single call. Also the setReadDataOnly method helps speed things up a bit by only loading the data from the cells without any special excel formatting.

When all source data has been added to the CLOB, we will write it to a flat-file in a single call. It's a pattern matching engine that is often embedded inside of other languages.

But, as you can guess, these cause further problems for programs- now, the commas of the world had safe haven usage inside of comma separated values, however, double quotes now could not be included inside of a double quote encased field value.

The tools that are provided by Oracle export, Data Pump, writeable external tables write data quickly, but in a proprietary format, so for true ASCII flat-files, we have to resort to our own homegrown utilities.

Both of the above code snippet prints output: Such is the life of a programmer: It is included in several utilities such as search functions inside of UltraEdit and Ace Text. That all said, I have chosen to write a regex pattern that can handle parsing the fields of a CSV with all the conditions I mentioned above.

We will run these on an 11g Release 1 database, but all examples are compatible with 10g and most of them with 9i. For this test, we will create a parallel pipelined function that writes the source data to flat-file and returns a single summary record per session.

The data to be dumped to flat-file will be sourced from a single table of 1 million rows, which we will create as follows. A simpler and possibly more elegant method is to use Oracle's parallel query PQ mechanism and create a parallel pipelined function to split the source data and dump it using multiple PQ slaves.

No Warrantees are implied or offered. For this we need ResultSet object.

Adrian Billington, February No support or service is offered or implied by your usage. This has a negligible impact overall. All examples in this article will use either implicit or explicit bulk fetches of the same size.

We have reduced our elapsed time to less than half the baseline: Both of the above code snippet prints output: This can also reduce the overall time it takes to access all of the source data; care should be taken over the resources required by the CLOB technique, particularly in PQ scenarios where it becomes unscalable.

This would the standard way of escaping a double quote character "by simply placing to double quote characters next to each other, as in "".

It is possible to map the result to a Java bean object. For example, sqlplus can spool data to flat-files very quickly, but it is a command utility and not part of the database. It returns a String array for each value in row.
