PHP program to add item at the beginning of associative array
To add an item at the beginning of the associative array, the code is as follows−
Example
Live Demo
<?php
$arr = array( "p"=>"150", "q"=>"100", "r"=>"120", "s"=>"110", "t"=>"115", "u"=>"103", "v"=>"105", "w"=>"125" );
echo "Initial Array...\n";
print_r($arr);
array_unshift($arr,"100");
echo "Updated Array...\n";
print_r($arr);
?>
Output
This will produce the following output−
Initial Array...
Array(
[p] => 150
[q] => 100
[r] => 120
[s] => 110
[t] => 115
[u] => 103
[v] => 105
[w] => 125
)
Updated Array...
Array (
[0] => 100
[p] => 150
[q] => 100
[r] => 120
[s] => 110
[t] => 115
[u] => 103
[v] => 105
[w] => 125
