You can also use references on foreach values   foreach  array as  elementKey   gt   amp  element            element is the same than  amp  array  elementKey      if  isset  element  id    and  element  id       searched value             unset  element

Be careful with the main answer   with     id   gt 1  cat   gt  vip      id   gt 2  cat   gt  vip      id   gt 3  cat   gt  normal     and calling the function  foreach  array as  elementKey   gt   element        foreach  element as  valueKey   gt   value            if  valueKey     cat   amp  amp   value     vip                  delete this particular object from the  array             unset  array  elementKey                         it returns   2  gt   id   gt 3  cat   gt  normal     instead of   0  gt   id   gt 3  cat   gt  normal     It is because unset does not re-index the array   It reindexes   if we need it    result     foreach  array as  elementKey   gt   element        foreach  element as  valueKey   gt   value             found false          if  valueKey      cat   amp  amp   value      vip                 found true               break                     if   found                result    element

I m not much of a php programmer  but I can say that in C  you cannot modify an array while iterating through it   You may want to try using your foreach loop to identify the index of the element  or elements to remove  then delete the elements after the loop

It looks like your syntax for unset is invalid  and the lack of reindexing might cause trouble in the future   See   the section on PHP arrays     The correct syntax is shown above   Also keep in mind array-values for reindexing  so you don t ever index something you previously deleted

This should do the trick       reset  array   while  list  elementKey   element    each  array         while  list  key   value2    each  element             if  key     id   amp  amp   value     searched value                 unset  array  elementKey
