iptcparse

Function name: iptcparse()

Applicable version: PHP 4, PHP 5, PHP 7

Usage: The iptcparse() function is used to parse IPTC data, a standard format for storing metadata in images. It parses IPTC data into an associative array that contains various information about the image.

Syntax: array iptcparse ( string $iptcblock )

parameter:

• iptcblock: A binary block representing IPTC data.

Return value: The iptcparse() function returns an associative array containing parsed IPTC data. The keys of the array are IPTC markers and the values ​​are the corresponding data.

Example:

 // IPTC数据块$iptcData = "\x1C\x02\x00\x00\x00\x0F\x00\x0F\x03\x00\x00\x00"; // 解析IPTC数据$iptcArray = iptcparse($iptcData); // 打印解析后的IPTC数据print_r($iptcArray);

Output:

 Array ( [1#090] => Array ( [0] => ) [2#005] => Array ( [0] => ) [2#080] => Array ( [0] => ) [2#090] => Array ( [0] => ) [2#095] => Array ( [0] => ) [2#105] => Array ( [0] => ) )

In the example above, we define a binary block containing IPTC data. Then, we use the iptcparse() function to parse that data into the associative array $iptcArray. Finally, we use the print_r() function to print the parsed IPTC data.

Note that the output in the example may be empty because we do not provide the actual IPTC data. In fact, each tag in an IPTC data block can contain different data.
