[PHP]spłaszczenie zagnieżdżonych tablic php 5.3.0, jak zrobić to najkrócej ? Opcje

[madrazel]

udało mi się znaleźć takie 2 skrypty:

Kod

<code><span class="html"><span class="default">  </span><span class="keyword">function </span><span class="default">array_flatten</span><span class="keyword">(</span><span class="default">$a</span><span class="keyword">) {
        foreach(</span><span class="default">$a </span><span class="keyword">as </span><span class="default">$k</span><span class="keyword">=></span><span class="default">$v</span><span class="keyword">) </span><span class="default">$a</span><span class="keyword">[</span><span class="default">$k</span><span class="keyword">]=(array)</span><span class="default">$v</span><span class="keyword">;
        return </span><span class="default">call_user_func_array</span><span class="keyword">(</span><span class="default">array_merge</span><span class="keyword">,</span><span class="default">$a</span><span class="keyword">);
      }</span></span></code>

Kod

<span class="ident">function</span> <span class="ident">flatten_array</span><span class="punct">(</span><span class="ident">array</span> <span class="global">$a</span><span class="punct">)</span> <span class="punct">{</span>

          <span class="keyword">if</span> <span class="punct">(</span><span class="ident">is_array</span><span class="punct">(</span><span class="global">$a</span><span class="punct">[</span><span class="global">$i</span><span class="punct">]))</span> <span class="punct">{</span>
              <span class="ident">array_splice</span><span class="punct">(</span><span class="global">$a</span><span class="punct">,</span> <span class="global">$i</span><span class="punct">,</span> <span class="number">1</span><span class="punct">,</span> <span class="global">$a</span><span class="punct">[</span><span class="global">$i</span><span class="punct">]);</span>
          <span class="punct">}</span> <span class="keyword">else</span> <span class="punct">{</span>
              <span class="global">$i</span><span class="punct">++;</span>
          <span class="punct">}</span>
      <span class="punct">}</span>
      <span class="keyword">return</span> <span class="global">$a</span><span class="punct">;</span>
  <span class="punct">}</span>

ale to są stare wpisy sprzed ponad roku, może jest w najnowszej wersji php jakaś jednolinijkowa funcja na to ?

o rany boskie a cóż to się stało że mi się kody nie chciały wkleić ?

Nie wiem czy jest gotowa funkcja ew. możesz napisać swoją.
Użyć do tego is_array i sprawdzać.

[PHP] pobierz, plaintext 
<?php
 
$a = array('jeden', 'dwa', array('trzy', 'cztery', array('piec')));
 
$n = array();
 
function testowa($x) {
	global $n;
	foreach ($x as $value) {
		if (!is_array($value)) {
			$n[] = $value;
		}else{
			testowa($value);
		}
	}
}
 
testowa($a);
 
echo '<pre>';
	print_r($n);
echo '</pre>';
 
?>
