En este art\u00edculo vamos a averiguar como saber si una carpeta o directorio est\u00e1 vac\u00edo o tiene elementos (subcarpetas o archivos) con PHP.<\/p>\n

Para saber si un directorio existe tendremos que crear la siguiente condicional:<\/p>\n

if (is_dir('folder')) {\r\n   \/\/c\u00f3digo\r\n}<\/pre>\n
La funci\u00f3n is_dir() indica si el elemento pasado por par\u00e1metro es un directorio o no. Retorna TRUE si es un directorio y FALSE si no lo es.<\/p>\n
Para saber si el directorio que estamos tratando tiene archivos dentro deberemos escanearlo. PHP dispone de una funci\u00f3n muy potente que te retorna los elementos del directorio en un array.<\/p>\n
En el c\u00f3digo que vamos a ver a continuaci\u00f3n veremos un ejemplo m\u00e1s completo<\/p>\n
\/\/Si es un directorio\r\nif (is_dir('folder')) {\r\n    \/\/Escaneamos el directorio\r\n    $carpeta = @scandir('folder');\r\n    \/\/Miramos si existen archivos\r\n\u00a0\u00a0 \u00a0if (count($carpeta) > 2){\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0echo 'El directorio tiene archivos';\r\n        \/\/Miramos si existe el archivo pasado como par\u00e1metro\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0if (file_exists('folder\/index.php')) \r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0echo 'El archivo existe';\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0else\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0echo 'El archivo no existe';\r\n\u00a0\u00a0 \u00a0}else{\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0echo 'El directorio est\u00e1 vac\u00edo';\r\n\u00a0\u00a0 \u00a0}\r\n}\r\nelse {\r\n\u00a0\u00a0 \u00a0echo 'El directorio no existe.';\r\n}<\/pre>\n
En el c\u00f3digo de ejemplo estamos haciendo varias cosas, primero miramos si el elemento que estamos tratando es un directorio y si lo es escaneamos su contenido con la funci\u00f3n scandir(). Comprobamos que haya elementos con count($carpeta) > 2, evitando los elementos que debemos ignorar \u00ab.\/\u00bb y \u00ab..\/\u00bb y ya dentro miramos si existe un archivo indicado con la funci\u00f3n file_exists().<\/p>\n","protected":false},"excerpt":{"rendered":"
