Pessoal, estou um tanto pérdido e preciso de uma força aqui

 

Preciso arranjar uma forma de varrer uma pasta e ver quais imagens (só tem imagens la) que tem la e depois ncomparar com uma lista que vem do MySql.

 

Depois, as nimagens que estiverem a mais na pasta que não tem na tabela do MySql, excluir essa imagem da pasta.

 

Como fazer isso?

Ok

agora, fiz assim:

<?php
$dir = "imagens/upload/venda/miniaturas/";

// Abre um diretorio conhecido, e faz a leitura de seu conteudo
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
           $NomesFotos[] = $file;
        }
        closedir($dh);
    }
}
$NomeTodasFotos = implode(';',$NomesFotos);
print $NomeTodasFotos;
?>
[/oode]
isso esta me retornando assim: (só tem duas fotos no diretorio)
[code]
.;..;2a3568999b212ce219fdae211f5a3f09.JPG;ff61f5f32cd8cf6ae950d1a0525c6609.JPG
[/code]
Minhas duvidas
Esse inicio|; 
[code]
.;..;
[/code]
Pode ser tirado com substring ou pode acontecer de esse inicio, dependendo o diretorio ou do numero de imagens pode mudar?

Olhe a ideia do codigo:
[code]

<?php 
header('Content-Type: text/html; charset=utf-8');
include ("global/funcoes_php/var.php");
include("global/funcoes_php/conexao.php"); 
$MySQL = new TMySQL();
$MySQL->connect($host, $db, $user, $pass);
?>

<?php
function varre ($dir) {
// Abre um diretorio conhecido, e faz a leitura de seu conteudo
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
           $NomesFotos[] = $file;
        }
        closedir($dh);
    }
}
$NomeTodasFotos = implode(';',$NomesFotos);
$NomeTodasFotos = substr($NomeTodasFotos, 5);
return $NomeTodasFotos;
} 
?>

Entendi.

Porem, pode ser que va imagens gif, png e não ha como controlar isso.

Então agora ja consegui criar uma string com os nomes vindos do banco e do diretorio separados por ; em duas variaveis.

 

Agora falta ver qual imagem nesta em uma e não esta na outra e criar a funçao para excluir essa imagem da pasta.

Segue o que eu ja consegui

 

<?php 
header('Content-Type: text/html; charset=utf-8');
include ("global/funcoes_php/var.php");
include("global/funcoes_php/conexao.php"); 
$MySQL = new TMySQL();
$MySQL->connect($host, $db, $user, $pass);
?>

<?php
function varre ($dir) {
// Abre um diretorio conhecido, e faz a leitura de seu conteudo
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
           $NomesFotos[] = $file;
        }
        closedir($dh);
    }
}
$NomeTodasFotos = implode(';',$NomesFotos);
$NomeTodasFotos = substr($NomeTodasFotos, 5);
return $NomeTodasFotos;
} 

   $sql=mysql_query("
	    select 
			ImoveisCadastroVenda.Foto, 
			ImoveisCadastroVenda.Foto2, 
			ImoveisCadastroVenda.Foto3, 
			ImoveisCadastroVenda.Foto4, 
			ImoveisCadastroVenda.Foto5, 
			ImoveisCadastroVenda.Foto6, 
			ImoveisCadastroVenda.Foto7, 
			ImoveisCadastroVenda.Foto8,
			ImoveisCadastroVenda.Foto9, 
			ImoveisCadastroVenda.Foto10 
		from 
		   ImoveisCadastroVenda 
		        ") or die("iiiiiiiii");
		
		while (list($Foto1,$Foto2,$Foto3,$Foto4,$Foto5,$Foto6,$Foto7,$Foto8,$Foto9,$Foto10) = mysql_fetch_row($sql)){
			$NomesFotos2[] = $Foto1.";".$Foto2.";".$Foto3.";".$Foto4.";".$Foto5.";".$Foto6.";".$Foto7.";".$Foto8.";".$Foto9.";".$Foto10;
//aqui vai a comparaçao
		}
		
		$NomeTodasFotos2 = implode(';',$NomesFotos2);
        $NomeTodasFotos2 = substr($NomeTodasFotos2, 5);
		print $NomeTodasFotos2."<P>";
		$dir = "imagens/upload/venda/miniaturas/";
		print varre($dir)."<P>";		

?>

hum... acho que trabalhar com arrays é bem mais simples, fácil e rápido..

 

algo como in_array, ou array_dif(ou algo assim..)

Utilize a flag GLOB_BRACE no segundo parâmetro de glob() para casar mais tipos de arquivos no padrão.

Algo assim:

 

$dir = 'imagens/upload/venda/miniaturas/*.{jpg,gif,png}';
$NomeTodasFotos = glob( $dir, GLOB_BRACE );

print_r( $NomeTodasFotos );

Não, não

 

Essa parte eu ja fiz.

Agora tenho duas variaveis com os nomes das imagens que vem do banco em uma variavel. Sendo que os nomes são separadas por ';':

$NomeTodasFotos2 = implode(';',$NomesFotos2);
$NomeTodasFotos2 = substr($NomeTodasFotos2, 5);
E tambem tenho uma variavel com os nomes das imagens que estão na pasta tambem separadas por ';':

$dir = "imagens/upload/venda/miniaturas/";
$NomeTodasFotos = varre($dir)
Conforme a função varre acima.

Agora preciso ver quais nomes de fotos estão na variavel $NomeTodasFotos2 e que não estão na variavel $NomeTodasFotos e excluir elas na pasta.

 

Como faço isso?

 

Tentei fazer assim mas não deu resultado algum:

 

preg_match($NomeTodasFotos2, varre($dir), $matches, PREG_OFFSET_CAPTURE);
print_r($matches);

To com uma previa do resultado das variaveis aqui:

Ve se ajuda:

preg_match($b, $a, $matches2, PREG_OFFSET_CAPTURE);
print_r($matches2);
Isso não imprime nada na tela e como podem ver a primeira imagem nas duas variaveis é mesma.

Sabe aquelas plaquinhas motivacionais: "U're doing it wrong!" ? Então...

 

<?php

# Parte do banco de dados
$conn = mysql_connect('localhost','root','') or die(mysql_error());
$db = mysql_select_db('imasters') or die(mysql_error());

$sql = "SELECT `foto`, `foto2`, `foto3`, `foto4`, `foto5`, `foto6`, `foto7`, `foto8`, `foto9`, `foto10` FROM `ImoveisCadastroVenda`";
$rs = mysql_query($sql, $conn) or die(mysql_error());

$fotosDb = array();
while(false !== ($row = mysql_fetch_row($rs))) $fotosDb = array_merge($fotosDb, $row);

# Fim da parte do banco de dados, início da parte de diretórios

chdir('imagens');
$fotosDiretorio = glob('*.{jpg,gif,png}', GLOB_BRACE);

foreach(array_diff($fotosDiretorio, $fotosDb) as $apagar) unlink($apagar);

Mas olha só:

 

Me responde uma coisa:

No codigo abaixo:

		  for ($i=0;$i<sizeof($NomesFotos2);$i++)
		  {
			  $fotografia[]=explode(";",$NomesFotos2[$i]);
		  }

		  for ($i=0;$i<mysql_num_rows($sql);$i++){
			 $foto[]="$"."fotografia[$i]";
		  }
		  $fotos= implode(',',$foto);

		  print $fotos;
		  $dir = "imagens/upload/venda/miniaturas/";
		  $NomeTodasFotos1= varre($dir);		
		  $result = array_diff($NomeTodasFotos1,$fotos);
		  print_r($result)."<p><p><p>";
Expecificadamente nessa parte

for ($i=0;$i<mysql_num_rows($sql);$i++){
			 $foto[]="$"."fotografia[$i]";
		  }
		  $fotos= implode(',',$foto);

		  print $fotos;
		  $dir = "imagens/upload/venda/miniaturas/";
		  $NomeTodasFotos1= varre($dir);		
		  $result = array_diff($NomeTodasFotos1,$fotos);
		  print_r($result)."<p><p><p>";
a variavel $fotos me retorna seguinte:

$fotografia[0],$fotografia[1],$fotografia[2],$fotografia[3],$fotografia[4],$fotografia[5],$fotografia[6],$fotografia[7],$fotografia[8],$fotografia[9],$fotografia[10],$fotografia[11],$fotografia[12],$fotografia[13],$fotografia[14],$fotografia[15]
porem, se eu jogar essa variavel como esta no codigo na array_diff, não funciona. Porem, se eu jogar seu conteudo la ai funciona.

Tipo:

		  $result = array_diff($NomeTodasFotos1,$fotografia[0],$fotografia[1],$fotografia[2],$fotografia[3],$fotografia[4],$fotografia[5],$fotografia[6],$fotografia[7],$fotografia[8],$fotografia[9],$fotografia[10],$fotografia[11],$fotografia[12],$fotografia[13],$fotografia[14],$fotografia[15] 
);
		  print_r($result)."<p><p><p>";
Porque?

Não entendo porque você está complicando tudo heheheh, fazendo explode's, implode's, for's. O Evandro já mostrou como fazer, de uma forma bem simples e que funciona.

 

Veja, o processo é gerar duas listas (arrays), uma contendo o nome das imagens salvas no banco de dados, e outra lista com os arquivos salvos no servidor. Feito isso, utilizando apenas uma função de array do PHP, você encontra as imagens que estão no servidor e não estão no banco de dados. Do resto é só mandar um unlink() nelas e acabou! Não precisa de fazer implode para depois fazer explode nem nada, é simples.

 

Aproveitando, vale a leitura: http://pt.wikipedia.org/wiki/Keep_It_Simple

Ok

 

Entendi mais ou menos.

Mas, e no caso de eu ter dois diretorios com as mesmas fotos (miniaturas e normais) como fazer se chdir só há uma vez no código?

 

<?php 
header('Content-Type: text/html; charset=utf-8');
include ("global/funcoes_php/var.php");
include("global/funcoes_php/conexao.php"); 
$MySQL = new TMySQL();
$MySQL->connect($host, $db, $user, $pass);

$sql = "SELECT `foto`, `foto2`, `foto3`, `foto4`, `foto5`, `foto6`, `foto7`, `foto8`, `foto9`, `foto10` FROM `ImoveisCadastroVenda`";
$rs = mysql_query($sql) or die(mysql_error());

$fotosDb = array();
while(false !== ($row = mysql_fetch_row($rs))) 
$fotosDb = array_merge($fotosDb, $row);

# Fim da parte do banco de dados, início da parte de diretórios

//chdir('imagens/upload/venda/miniaturas/');
chdir('imagens/upload/venda/normais/');
$fotosDiretorio = glob('*.{JPG,JPEG,GIF,PNG,jpg,jpeg,gif,png}', GLOB_BRACE);

foreach(array_diff($fotosDiretorio, $fotosDb) as $apagar) unlink($apagar);

?>

Ok.

Entendido todo o processo mas, só para a questão de aprendizado mesmo.

 

E, se no diretorio, tiver por exemplo, arquivos .doc e não tiver como voce ter controle disso, como seria?

Pergunto pois ai não haverá como usar a função glob. 

chdir('imagens/upload/venda/normais/');
$fotosDiretorio = glob('*.{JPG,JPEG,GIF,PNG,jpg,jpeg,gif,png}', GLOB_BRACE);
Ou vai?

Nesse casoi deveria ser do jeito que eu estava fazendo mesmo né?

           $NomesFotos[] = $file;
        }
        closedir($dh);
    }
}
$NomeTodasFotos = implode(';',$NomesFotos);
$NomeTodasFotos = substr($NomeTodasFotos, 5);
$NomeTodasFotos = explode(';',$NomeTodasFotos);
return $NomeTodasFotos;
