Pushing a value into an array automatically creates a numeric key for it   When adding a key-value pair to an array  you already have the key  you don t need one to be created for you  Pushing a key into an array doesn t make sense  You can only set the value of the specific key in the array      no key array push  array   value      same as   array      value      key already known  array  key     value

A bit late but if you don t mind a nested array you could take this approach    main array   array      Your array that you want to push the value into  value   10    The value you want to push into  main array array push  main array  array  Key    gt   value      To clarify   if you output json encode  main array  that will look like    Key   10

Nope  there is no array push   equivalent for associative arrays because there is no way determine the next key    You ll have to use   arrayname indexname     value

hi i had same problem i find this solution you should use two arrays then combine them both    lt  php   fname array  Peter   Ben   Joe      age array  35   37   43      c array combine  fname  age    print r  c      gt    reference   w3schools

Exactly what Pekka said     Alternatively  you can probably use array merge like this if you wanted   array merge   GET  array  rule 0    gt   rule 1       But I d prefer Pekka s method probably as it is much simpler

I was just looking for the same thing and I realized that  once again  my thinking is different because I am old school  I go all the way back to BASIC and PERL and sometimes I forget how easy things really are in PHP   I just made this function to take all settings from the database where their are 3 columns  setkey  item  key   amp  value  value  and place them into an array called settings using the same key value without using push just like above   Pretty easy  amp  simple really       Get All Settings  settings getGlobalSettings         Apply User Theme Choice  theme choice    settings  theme        etc etc etc          function getGlobalSettings          dbc   mysqli connect wds db host  wds db user  wds db pass  or die  MySQL Error      mysqli error         mysqli select db  dbc  wds db name  or die  MySQL Error      mysqli error          MySQL    SELECT   FROM systemSettings        result   mysqli query  dbc   MySQL       while  row   mysqli fetch array  result                       settings  row  item       row  value         NO NEED FOR PUSH               mysqli close  dbc   return  settings        So like the other posts explain    In php there is no need to  PUSH  an array when you are using   Key    Value  AND    There is no need to define the array first either     array array     Don t need to define or push  Just assign  array  key     value  It is automatically a push and a declaration at the same time   I must add that for security reasons   P oor  H elpless  P rotection  I means Programming for Dummies  I mean PHP     hehehe I suggest that you only use this concept for what I intended  Any other method could be a security risk  There  made my disclaimer

You can use the union operator     to combine arrays and keep the keys of the added array  For example    lt  php   arr1   array  foo    gt   bar     arr2   array  baz    gt   bof     arr3    arr1    arr2   print r  arr3       prints     array        foo    gt   bar         baz    gt   bof           So you could do   GET    array  one    gt  1      There s more info on the usage of the union operator vs array merge in the documentation at http   php net manual en function array-merge php
