    2. COThe answer is "with code". There is no function or accepted way of doing this. You just need to program a solution, which is **too localized** for Stack Overflow. Hint: The answer will involved the `[]`, or "array indexing" operator. You should sit down and read a tutorial on PHP.

    3. COPrasanthBendra I want to fill the missing sum to getting $value $value=?+?+? that the point meagar That the reason I asked here because I cannot find any match function to doing this. 458752 is the defined/ inputed value $value the 0+458752+0 is array how to calculated it, look like fill a missing value till it equal but with an array key

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
