I know this is an old answer but it might be helpful for others to know that another difference between the two is that if you have to add more than 2 3 values per loop to an array it s faster to use        for  i   0   i  lt  10   i               array push  arr   i   i 2   i 3   i 4                instead of        for  i   0   i  lt  10   i               arr      i            arr      i 2            arr      i 3            arr      i 4                        edit- Forgot to close the bracket for the for conditional

You can add more than 1 element in one shot to array using array push    e g   array push  array name   element1   element2       Where  element1   element2     are elements to be added to array   But if you want to add only one element at one time  then other method  i e  using  array name    should be preferred

You should always use  array   if possible because as the box states there is no overhead for the function call  Thus it is a bit faster than the function call

When you call a function in PHP  such as array push     there are overheads to the call  as PHP has to look up the function reference  find its position in memory and execute whatever code it defines   Using  arr      some value   does not require a function call  and implements the addition straight into the data structure  Thus  when adding a lot of data it is a lot quicker and resource-efficient to use  arr

The difference is in the line below to  because in that way there is no overhead of calling a function       array push   will raise a warning if the first argument is not   an array  This differs from the  var   behaviour where a new array is   created
