[Solved] not scraping website with PHP [closed]

by

[ad_1] The reason why this isn’t working is because the actual website got a lot more between “Summary:” and the “<span class…” What you could try (that seems to work) is to change it into the simpler form: $contents=file_get_contents(“http://www.weather-forecast.com/locations/San-Francisco/forecasts/latest”); preg_match(‘/<span class=”phrase”>(.*?)<\/s/’, $contents,$matches); print_r($matches[0]); This will pick out more matches, but since we’re only interested in … Read more

[Solved] How to use recursion to sum specific values in a multidimensional array?

by

[ad_1] Recursion doesn’t seem to be necessary for the “parent” direct values, so that can be done with a direct foreach loop. The “children” indirect values require recursion. I’ve elected to use array_walk_recursive() to access every “leaf node” in the array. This will also store the parents’ indirect values too, so I subtract those values … Read more

[Solved] PHP switch trouble [closed]

by

[ad_1] the expression ($item>=17) && ($item<=20) evaluates to 0, as the value of $item is 0. the switch-case statement will merely match the value of $item with case values. So, your code, in first case is equivalent to switch($item){ case (1): $case=”<16″; break; case ( 0): $case=”>=17_<=20″; break; case ( 0): $case=”>=21_<=25″; break; } 0 … Read more
