Mod_rewrite檢查php文件是否存在

Question

我正在嘗試編寫一些mod_rewrite規則。 目前一切正常。 目前，我的通用網址如下所示：

http://website.com/about-us
http://website.com/privacy

目前，這兩個鏈接是mod_rewritten到content.php ，因為about-us和privacy不存在.php文件，而是它們的內容存儲在content.php檢索的數據庫中。

我有另一個網址：

http://website.com/contact-us

哪個確實存在.php文件，因為它包含自定義數據。 如何查看contact-us.php存在。 如果是，請將website.com/contact-us重定向到website.com/contact-us.php ，否則，重定向到website.com/content.php

下面是我的mod_rewrite文件：

RewriteEngine On

# I want the following condition and rule to look to see if the .php file exists,
# and if it does, redirect to the physical page, otherwise, redirect to content.php
RewriteCond %{DOCUMENT_ROOT}/([a-zA-Z0-9\-_]+).php -f
RewriteRule ^([a-zA-Z0-9\-_]+)\.php$ [L]


RewriteRule ^([a-zA-Z0-9\-_]+)$ /content.php [L]
RewriteRule ^(product1|product2|product3)/(designer1|designer2|designer3)$ /search.php?productType=$1&designer=$2 [L]
RewriteRule ^sale/(product1|product2|product3)$ /search.php?sale=1&productType=$1 [L]

如果您需要任何進一步的信息，請告訴我！ 我很感謝回復:)

Answer 1

將.htaccess代碼更改為

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d # not an existing dir
RewriteCond %{REQUEST_FILENAME} !-f # not an existing file
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}\.php -f # and page.php exists

# redirect to the physical page
RewriteRule ^(.*)$ $1.php [L]

# otherwise, redirect to content.php
RewriteRule ^ /content.php [L]

RewriteRule ^sale/(product[123])$ /search.php?sale=1&productType=$1 [QSA,NC,L]
RewriteRule ^(product[123])/(designer[123])$ /search.php?productType=$1&designer=$2 [QSA,NC,L]

我還簡化了其他RewriteRule的模式匹配。 注意使用[QSA]自動轉發任何額外的查詢參數，使用[NC]使匹配不區分大小寫。

我會用這個：

#
# redirect first the evidences:
#
RewriteRule ^(product1|product2|product3)/(designer1|designer2|designer3)$ /search.php?    productType=$1&designer=$2 [L]
RewriteRule ^sale/(product1|product2|product3)$ /search.php?sale=1&productType=$1 [L]

#
# redirect then the generality:
#
RewriteCond %{DOCUMENT_ROOT}%%{REQUEST_URI}.php -f
RewriteRule ^ %{DOCUMENT_ROOT}%%{REQUEST_URI}.php [L]

#
# all other requests are rewritten to /content.php:
#
RewriteRule ^ /content.php [L]
