文本文件数据库处理函数库_PHP

inputfunctiondeal withdatabasedocumenttext

因为我租不起MySQL支持 所以只能采用扁平文件存储

我是采用perl常用的
"|"定界的格式就像 "name|email|homepage" 这样的格式。

随便写了几个函数
觉得还是有点用处的。 大家有什么心得

也希望能告诉我啊
我来完善完善。






// dtf.inc.php3

// DTF -- Delimited Text File Functions

// Function to manage a delimited text file database



function dtf_fetch_all_as_string($filename) {

$fp = fopen( $filename, "r" );

$current = fread($fp, filesize($filename));

fclose($fp);

return $current;

}





function dtf_fetch_all_as_array($dbname) {

return file($dbname);

}



function dtf_update_db($dbname, $item) {

if (file_exists($dbname)):

$fp = fopen($dbname,"w+");

fputs($fp,$item);

fclose($fp);

else:

$fp = fopen($dbname,"w");

fputs($fp,$item);

fclose($fp);

endif;

}



function dtf_get_total_rows($dbname) {

return count(file($dbname));

}



function dtf_remove_pipe($input) {

if (is_string($input)) {

// $input=ereg_replace("|","",$input); // It’s said that str-replace is faster than ereg_replace

$input=str_replace("|","",$input);

}

if (is_array($input)) {

for ($i=0; $i
$input[$i] = ereg_replace("|","|",$input[$i]);

}

}

return $input;

}





// 这个函数没有用, 用htmlspecialchars就可以

// 但是如果只需要处理""而不需要处理 引号和 &时就很有用

function dtf_remove_html_tag($input) {

if (is_string($input)) {

$input = ereg_replace("
$input = ereg_replace(">",">",$input);

}

if (is_array($input)) {

for ($i=0; $i
$input[$i] = ereg_replace("
$input[$i] = ereg_replace(">",">",$input[$i]);

}

}

return $input;

}





// 可以定制这个函数, 控制是否允许html标记等

function dtf_sanitize($input) {

$input = dtf_remove_pipe($input);

// $input = dtf_remove_html_tag($input);

$input = stripslashes($input);

$input = htmlspecialchars($input);

return $input;

}

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
