PHP: How do I check the contents of an array for my string? -

-

I have a string which is coming from my database table, say $ needle. If the needle is not in my array, then I want to add it to my array.

If it is in my array, it is only in two times, even if I want to add it to my array (it will be three times maximum)

To see it Is the $ needle in my $ gear array, do I need a loop through the array with the strokes (or is there a quick method)?

The table has many needles, so I'm starting looping through the selection result.

This is the schematic of what I am trying to do ... 

  $ haystack = array (); While ($ line = mysql_fetch_assoc ($ result)) {$ needle = $ line ['data']; $ Num = no $ $ in needle $ hejstack $ / $ haystack is an array if ($ num <3) {$$ haystack [] = $ needle; // hope that it connects the needle}} // end time Get the next needle? Do anyone know how I should do this: 
 
  $ num = no $ needle $ hansstack  
 
 Thank you

You first use the value for each value to build the map , And after that only the value can increase if the value was calculated in the map & lt; 3, For example: 

  $ original_values_count = array_count_values ​​($ value); Forex currency ($ value as $ value) if ($ parent_man value_value [$ value] & lt; 3) $ value [] = $ value; Can not be completely avoided in the form of a loop, I can say that it is a good idea to choose the option to use the native PHP function in terms of speed compared to looping manually, all values ​​manually.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
