Convert to an array of strings At some point, you might want to create a CSV file and read it in these files, which means you need to convert those strings separated by commas into data. If the data was originally retrieved from the database, it is likely that it will only provide you with an array. At this point, y

Analysis of computer network protocol headers-Ethernet

Brief Analysis of the network protocol header-Ethernet [Ethernet protocol frame structure] when it comes to the Ethernet frame structure, its historical evolution is slightly chaotic. We will introduce the evolution of Ethernet standards. In 1980, DEC, schile, and Intel jointly developed the Ethernet I standard, defining the Ethernet frame format for the first time. On 1982, www.2cto.com updated the first version of www.2cto.com, which mainly changed the physical interface and the frame format r

Difference and connection between three access methods: PPPT, PPPoE, and PPPoA

Presumably, you should be familiar with ADSL and other access methods. We have learned that PPPT, PPPoE, and PPPoA should be available. So what are the differences and associations between the three access methods? Let's take a look at it in detail. First, let's look at the concept of the Bridge CPE method. 1) Bridging Mode: equivalent to connecting to a HUB. IP addresses must be set at both ends. For example, if the adsl modem works with the computer and a fixed IP address is assigned to the co

create a CSV file, which means you need to convert the data to a comma-delimited string. If the data was originally retrieved from the database, it is likely to provide an array. At this point, you can use the implode () function to combine array elements into a single string. As shown below: $csv =implode (",", $record); 6.
