Hola, he utilizado el buscador y no he encontrado mi duda.
Estoy tratando de hacer a mano una comprobación de tags de BBCode, que compruebe que las etiquetas abiertas de cada tipo estén luego cerradas.
He intentado utilizar tanto eregi() como preg_match(), pero no consigo utilizarlas correctamente. Según he oído eregi() está deprecated.
Sería algo así:
function str_postea($cadena1,$cadena2,$texto) {
$contador=0;
while(preg_match('/'.$cadena1.'/',$texto))
$contador++;
while(preg_match('/'.$cadena2.'/',$texto))
$contador--;
while($contador>0) {
$texto = $texto.$cadena2;
$contador--;
}
while($contador<0) {
$texto = str_replace($cadena2,"",$texto);
$contador++;
}
return $texto;
}
$texto = str_postea("[b]","[/b]",$texto);
El problema es que los primeros while de la función son infinitos, pues si existe la cadena, existe siempre. ¿Alguna idea de cómo podría arreglarlo?
Gracias.
Mira si esto te sirve, es el BBCode Parser que viene con el editor Markitup.

Con este sistema no tengo que hacer el follón del contador. Es más simple de lo que pensaba :-*
Resuelto, ¡Muchas gracias!
