php追加到数组
$myArr = [1, 2, 3, 4];
array_push($myArr, 5, 8);
print_r($myArr); // [1, 2, 3, 4, 5, 8]
$myArr[] = -1;
print_r($myArr); // [1, 2, 3, 4, 5, 8, -1]
将数组添加到数组php
<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
/*
Array
(
[color] => green
[0] => 2
[1] => 4
[2] => a
[3] => b
[shape] => trapezoid
[4] => 4
)
*/
?>
array_push php
// array_push ( array &$array [, mixed $... ] ) : int
// 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:
<?php
$array[] = $var;
?>
// repeated for each passed value.
// Note: If you use array_push() to add one element to the array, it's better to use $array[] = because in that way there is no overhead of calling a function.
php在数组中插入
$original = array( 'a', 'b', 'c', 'd', 'e' );
$inserted = array( 'x' ); // not necessarily an array, see manual quote
array_splice( $original, 3, 0, $inserted ); // splice in at position 3
// $original is now a b c x d e
数组推送php
<?php
$a=array("red","green");
array_push($a,"blue","yellow");
print_r($a);
?>
