How to add array element with increasing number of keyed arrays in PHP?
I have an array $a
$a[1] = "A";
$a[2] = "B";
$a[3] = "C";
$a[4] = "D";
Let's say "X"
is a new value that I want to add the middle position at array
, I want to add it to the second position array
, which $a[2]
, but I want to increment the counter keys
array
, which will become:
$a[1] = "A";
$a[2] = "X";
$a[3] = "B";
$a[4] = "C";
$a[5] = "D";
In this case I want to implement it in a loop, checking some conditions with if, I tried using slice and splice, both don't work
Do it as shown below: -
<?php
$a = array( 1=>'A', 2=>'B', 3=>'C', 4=>'D' );
$b = array( 'x' );
array_splice( $a, 1, 0, $b );
$a = array_combine(range(1, count($a)), array_values($a));
print_r($a);
Output: - https://eval.in/837366
I think you can try this
$a = array( 'a', 'b', 'c', 'd', 'e' );
$b = array( 'x' );
array_splice( $a, 3, 0, $b ); // splice in at position 3
Use php funtion for this array_splice
<?php
$a = array( 'A', 'B', 'C', 'D', 'E' );
$b = array( 'X' ); // array optional or
//$b= 'x';
array_splice( $a, 1, 0, $b ); // splice in at position 1
print_r($a);
?>
