Associative array replace

These arrays contains same keys simple like follow topic (prop is unique): Check if associative array contains value, and retrieve key / position in array

<?php
$array = array(
array("prop" => "1", "content" => "text"),
array("prop" => "2", "content" => "text"),
array("prop" => "3", "content" => "text"),
array("prop" => "4", "content" => "text")
);
$found = current(array_filter($array, function($item) {
  return isset($item['prop']) && 3 == $item['prop'];
}));
print_r($found);

I got prop 3: 

Array
(
  [prop] => 3
  [content] => text
)

So I want to replace value in $array with:

array("prop" => "3", "content" => "replaced text")

Since prop is unique, just extract the arrays using prop as the index and then access it that way:

$array = array_column($array, null, 'prop');
$array[3]['content'] = 'replaced text';

You might want to use an isset to make sure $array[3]['content'] exists.
