regexp with preg_split doesn't work as expected

Question

I tested here regexpal.com and it should match, but it doesn't...

$tabla_contenido = "ouseout=\"sacarobs();\">06/01/2014&nbsp;10:21</a></td><td align='right'><a class='texto'><b>Pendiente</b></a></td><td align='right'><a class='texto'><b>Pendiente</b></a></td><tr class='eltr' onclick=\"ventana('mostrar_nota_de_pedido.php?nnp=117&ven=152&cli=0001&scl=C07&pr=96244651', 'pedidos_listadoNelson');\" ><td align='right'><a class='texto'>117</a></td><td align='right'><a c";
$tabla_data = preg_split("|<tr([^>.]|\.|\,)*>|", $tabla_contenido);
foreach ($tabla_data as $line){
    echo $line."\n\n\n";
}

$tabla_data is empty

first at all, choose a delimiter that is not a special character. This alternation ([^>.]|\.|\,)* has no sense, replace it with [^>]* . — Casimir et Hippolyte

The problem is that you are not escaping the | inside your regular expression. The easiest solution is to use a different delimiter, such as ~:

$tabla_data = preg_split("~<tr([^>.]|\.|\,)*>~", $tabla_contenido);

Alternatively, you could escape the | character with a backslash, i.e. | would become \|, but it makes your regex a bit unreadable, so I suggest using a different delimiter instead.
