How smart is perfectly compatible with php5.5 and preg_replace_callback How to replace preg_replace

Source: Shangpin China | Type: website encyclopedia | Time: 2015-05-29
Now the PHP 5.5 version comes out, and I installed some changes. The smart we used is incompatibility, and the following error occurs once running:
preg_replace():
 

This means that the/e parameter in preg_replace_callback is replaced by preg_replace_callback, which may be cancelled in PHP 5.5 for security reasons, but the preg_replace_callback function is not easy to use, I removed the preg_replace (e in $search.'e ') in the 270th line of the Smarty_Compiler.class.php file. It was really good, but the problem came up again. The chance of this problem coming up was not many. It was just that the php tag code {php} {/php} could not be written in the smart template.

There is no way to replace the preg_replace() with the preg_replace_callback() function. The specific replacement method is as follows:

Add a method to the Smarty_Compiler class:

function callback_source($matches){
return "".$ this->_quote_replace($this->left_delimiter). "php".str_repeat("n",substr_count("","n")). "".$ this->_quote_replace($this->right_delimiter). "";
}

Then find around line 270:
$source_content = preg_replace($search.'e', "'"
. $this->_quote_replace($this->left_delimiter) . ' php'
. "' . str_repeat("n", substr_count('\0', "n")) .'"
. $this->_quote_replace($this->right_delimiter)
. "'"
, $source_content);

Replace with:

$source_content = preg_replace_callback($search,
array("self","callback_source")
, $source_content);

That's fine, so it's perfectly compatible with php5.5.
