Manual: array_push

Updated

array_push

(PHP4 )

array_push -- Push one or more elements onto the end of array

Description

int array_push (array array, mixed var [, mixed ...])

Array_push() treats array as a stack, and pushes the passed variables onto the end of array. The length of array increases by the number of variables pushed. Has the same effect as:
$array[] = $var;
repeated for each var.

Returns the new number of elements in the array.

Example 1. Array_push() example
$stack = array (1, 2); array_push ($stack, "+", 3);

This example would result in $stack having 4 elements: 1, 2, "+", and 3.

See also: array_pop(), array_shift(), and array_unshift().

$array[] = $var; works with php 3... array_push will not create an array for you... The variable must already exist, and must be an array. Go with the old if you are not sure what your doing.

Could someone tell me how to delete elements from, or somehow wipe out an array in PHP 3.0 (can't use array_pop in this version...)? I need to reuse the array, but put less elements in. Any help would be terriffic. -a

It's possible to delete an array (at least in php 3) using "unset ($arrayname);" (without the quotes).

How does one push a key value pair into a php3 array. This implementation seems logical, but it is unacceptable to PHP3 parser: Array[] = "Name"=>AnotherArray; this implementation is based on the example given in the user notes of the array function: $users = array("djuan"=>array(.... If a discrete pair is (key,array) then one ought to be able to push a pair onto an array. This however does not seem to be the case with the php3 syntax. Looking forward to an answer...

I finally found the answer to the above question. If you want to push a key value pair onto an associative array. This is the "correct" syntax. Array[$Key] = AnotherArray; Hope this helps somebody.

If you want to add a element to a linear table (one dimensional) the traditional method is best.<pre>$array_name[]=$variable_name</pre>. On the other hand if you want to insert a <pre>($key,$val)</pre> into an array the easy way is <pre>$array_name[$key]=$val</pre>. Thats all.

is there one function in php, that can delete an element from an array and shift the rest of the elements up or down, so that there is no empty location in the array.

Hi there, Does anyone know how to add elements to an ALREADY EXISTING 2 dimentional array? Regards,SC.

I needed to use array_push with PHP3, and instead of array_push($array,$item) I used $array[count($array)] = $item, to add the last element. Works if you have number-based arrays (i.e elements are ordered).

Can someone help me with php3 ? I've got this table with field productid and productdescription, now I want the user to see the productdescription and if selected it should return the value productid, this table is highly dynamic; How do I fill this array for a combo box ?!?

This has already been asked but how do I push an element onto a two dimentional array in PHP4? I tried <pre>array_push($array[Sub_array],element);</pre> to no avail.
