a.PHP -> HTML & JavaScript
额 超简单,我也要写= =~
html代码中
/>
JavaScript代码中
复制代码 代码如下:
b.PHP MySQL
php代码中
复制代码 代码如下:
$dbcnx = @mysql_connect ( "localhost", "root", "1234" );
if (! $dbcnx) {
echo ("Unable to connect to the " . "database server at this time.");
exit ();
}
if (! @mysql_select_db ( "pms" )) {
echo ("Unable to locate the joke " . "database at this time.");
exit ();
}
mysql_query ( "SET NAMES 'GB2312'" );
$q=mysql_query("select * from ability where ALV = 1");
while($row=mysql_fetch_array($q)){
$array1[] = $row[AName];
}
?>
2.HTML
a. HTML -> PHP (POST方式)
html代码中
复制代码 代码如下:
do.php 文件代码中
复制代码 代码如下:
echo $_POST['count'];
?>
b. HTML -> JavaScript
JavaScript代码中 (可获得,可更改)
复制代码 代码如下:
3.JavaScript
a. JavaScript -> HTML (通用法, 未验证)
JavaScript代码中
复制代码 代码如下:
html代码
复制代码 代码如下:
b. JavaScript -> PHP
通过html的转接
1.JavaScript代码先给html
复制代码 代码如下:
2.html代码给php
复制代码 代码如下:
3.do.php接收到
复制代码 代码如下:
echo $_POST['count'];
?>

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.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
