PHP code 1: Merging two indexed arrays

PHP代碼1：合并兩個索引數組

<?php$arr1 = array(10, 20, 30, 40, 50);$arr2 = array(60, 70, 80, 90, 10);//merging arrays$arr3 = array_merge($arr1, $arr2);//printing print_r ($arr3); ?>

Output

輸出量

Array ([0] => 10[1] => 20[2] => 30[3] => 40[4] => 50[5] => 60[6] => 70[7] => 80[8] => 90[9] => 10 )

PHP code 2: Merging two associative arrays having different keys and values

PHP代碼2：合并兩個具有不同鍵和值的關聯數組

<?php$arr1 = array("a" => "Hello", "b" => "Hi");$arr2 = array("c" => "Bye!", "d" => "Nothing");//merging arrays$arr3 = array_merge($arr1, $arr2);//printing print_r ($arr3); ?>

Output

輸出量

Array ([a] => Hello[b] => Hi[c] => Bye![d] => Nothing )

PHP Code 3: Merging two associative arrays having different keys and duplicate value

PHP代碼3：合并兩個具有不同鍵和重復值的關聯數組

<?php$arr1 = array("a" => "Hello", "b" => "Hi");$arr2 = array("c" => "Hello", "d" => "Hi");//merging arrays$arr3 = array_merge($arr1, $arr2);//printing print_r ($arr3); ?>

Output

輸出量

Array ([a] => Hello[b] => Hi[c] => Hello[d] => Hi )

PHP Code 4: Merging two associative arrays having duplicate keys and unique values

PHP代碼4：合并兩個具有重復鍵和唯一值的關聯數組

<?php$arr1 = array("a" => "Hello", "b" => "Hi");$arr2 = array("a" => "Okay!", "d" => "Nothing");//merging arrays$arr3 = array_merge($arr1, $arr2);//printing print_r ($arr3); ?>

Output

輸出量

Array ([a] => Okay![b] => Hi[d] => Nothing )

PHP Code 5: Merging indexed and associative arrays

PHP代碼5：合并索引數組和關聯數組

<?php$arr1 = array(10, 20, 30, 40);$arr2 = array("c" => "Hello", "d" => "Hi");//merging arrays$arr3 = array_merge($arr1, $arr2);//printing print_r ($arr3); ?>

Output

輸出量

Array ([0] => 10[1] => 20[2] => 30[3] => 40[c] => Hello[d] => Hi )
