How php converts text files to csv files
This article mainly introduces how php converts text files to csv files. It is a very practical technique to implement the function of converting text files to output files through inheritance and extension of the SplFileObject class,
Do a share of the function, the text image in the form of CSV to share to the mail and other applications.First, CSV comma-separated value file format (comma-separated values), plain text form, comma-delimited, row of data does not cross the line.Picture converted to Base64 string Publicstring WriteBase64 (string path)
Univocity-parsers is an open-source Java project. For csv/tsv/fixed-width text file parsing, it provides a rich and powerful function with the Simple API development interface. Further introductions will be made later.Unlike other analytic libraries, Univocity-parsers has designed a set of own architectures based on high performance and scalability. Based on this architecture, developers can build a new fil

The contents in csv format are separated by commas (,). In reality, the content can be split. Each line is followed by a '\ n' branch.
Then, execute the output at the end. For example
The code is as follows:
$ Filename = "plcnetinfo_00000000date0000.csv ";Header ("Content-type: application/vnd. ms-excel ");Header ("Content-Disposition: attac
back. For example
Copy the Code code as follows:$filename = "plcnetinfo_{$date}.csv";Header ("Content-type:application/vnd.ms-excel");Header ("content-disposition:attachment; Filename= $filename ");
Header ("expires:0");Header ("Pragma:public");Header ("Cache-control:must-revalidate, Post-check=0, pre-check=0");Header ("Cache-control:public");Echo (Mb_convert_encoding ($exportdata, "gb2312", "UTF-8"));
However, when exporting the number,
PHP can quickly read the encapsulation class sharing of large CSV files by line (also applicable to other large text files ). The reading of large CSV files has been described earlier (PHP code example for reading and processing large CSV files by row ), however, there are still some problems in how to quickly and comp
run the output in the back. For example
Copy Code code as follows:
