1. PHP dynamic generation

Step one: Write JS code directly in the PHP file and declare in the header that this is a JavaScript file

Copy the code The code is as follows:

Step 2: Escape JavaScript with PHP output Code
Copy code The code is as follows:
function jsformat($str)
{
$str = trim($str );
$str = str_replace('\s\s', '\s', $str);
$str = str_replace(chr(10), '', $str);
$ str = str_replace(chr(13), '', $str);
$str = str_replace(' ', '', $str);
$str = str_replace('\', '\\' , $str);
$str = str_replace('"', '\"', $str);
$str = str_replace('\'', '\\'', $str);
$str = str_replace("'", "'", $str);
return $str;
}

Directly call jsformat($str)
The last step: proceed URL rewriting, for example, the PHP address is xxx/123.php, as long as it is rewritten to xxx/123.js, the purpose has been achieved.

Take PHPCMS as an example

Copy the code The code is as follows:
< ?php header('Content-Type: application/x-javascript; charset=UTF-8');?>
{pc:content action="position" posid="1" order="id DESC" num ="7" $catid=11}
function jsformat($str){
$str = trim($str);
$str = str_replace('\s\ s', '\s', $str);
$str = str_replace(chr(10), '', $str);
$str = str_replace(chr(13), '', $str );
$str = str_replace(' ', '', $str);
$str = str_replace('\', '\\', $str);
$str = str_replace(' "', '\"', $str);
$str = str_replace('\'', '\\'', $str);
$str = str_replace("'", "'" , $str);
return $str;
}
?>
{loop $data $v}
document.writeln("");?>");
{/loop}
{/pc}

Use document.writeln() to write the transferred code in each cycle.

2. PHP include JS file

Introduce a php link by writing javascript in html. The php is actually a file that generates js:

Copy the code The code is as follows:

if (20 == $ad_type_id) { // Couplet
ob_start ();
include TMPL_PATH . 'Code/duilian.js';
header("content-type: application/ x-javascript");
$code = ob_get_clean ();
echo $code;
}

Include js files in php, variables such as var swf in js, var swf = '', use ob cache here, pay attention to add header ("content-type: application/x-javascript") to allow browsing The server knows that this is a javascript script file.
