I need to do a sum of values from an xml file. As I have not worked with Curl extracting data from another file or page, I do not even know how to start. the file layout would be this.
0|0|0|0|3|0|0|46.000|
The value to be added would be the 46,000 + values of the next lines. More should be considered only the lines that have the value 3.
Does anyone have any type code? I already researched and found nothing related.
Just use preg_match_all to find all rows that fit a certain pattern (including the 3 character in the fifth position), and then add all the values found in the eighth position of each line:
preg_match_all('/\d+\|\d+\|\d+\|\d+\|3\|\d+\|\d+\|(\d+\.\d+)\|/',
$valores, $encontrados);
$total = 0;
foreach ($encontrados[1] as $encontrado) {
$total += floatval($encontrado);
}
If you do not know: the first argument of preg_match_all is a regular expression, and its purpose is to find all occurrences in a text that fit that expression - in this case, the format of the data you need.
