I want to implode this array to make a string with all keys = 'Palabra'. How can this be done? (the output should be: 'juana es')
Array
(
[0] => Array
(
[Palabra] => juana
)
[1] => Array
(
[Palabra] => es
[0] => Array
(
[Raiz] => ser
[Tipo] => verbo
[Tipo2] => verbo1
)
)
)
function foo( $needly, $array ) {
$results = array();
foreach ( $array as $key => $value ) {
if ( is_array( $value ) ) {
$results = array_merge($results, foo( $needly, $value ));
} else if ( $key == $needly ) {
$results[] = $value;
}
}
return $results;
}
echo implode( " ", foo( "Palabra", $your_array ) );
I ended using the foreach for lack of a better solution:
foreach ($array as $key => $palabra) {
$newArray[] = $array[$key]["Palabra"];
}
$string = implode(' ', $newArray);
I think the simplest solution is with array_walk_recursive.
<?php
$arr = array(
array(
'Palabra' => 'juana',
),
array(
'Palabra' => 'es',
array(
'Raiz' => 'ser',
'Tipo' => 'verbo',
'Tipo2' => 'verbo1',
),
),
);
$str = array();
array_walk_recursive($arr, function($value, $key) use(&$str) {
if ($key == 'Palabra') {
$str[] = $value;
}
});
$str = implode(' ', $str);
echo "$str\n";
The function passed in is called for each key-value pair in the array and any subarrays. Here we append any values with a matching key to an array and then implode the array to get a string.
