Preg_replace How to replace Preg_replace_callback

Younger brother previously engaged in Delphi development, was forced to learn PHP society, today blow directly blindfolded.
How to change this, the program error needs to replace the preg_replace into Preg_replace_callback

$fields = Preg_replace ('/([a-za-z0-9_]+) \. ( [a-za-z0-9_*]+)/E ', "\ $this->_getfieldtable (' \\1 '). \\2 ' ", $fields);

Reply to discussion (solution)

This is too difficult!!!!

$fields = Preg_replace ('/([a-za-z0-9_]+) \. ( [a-za-z0-9_*]+]/', function ($r) {  return $this->_getfieldtable ($r [1]). $r [2];  }, $fields);

$fields = Preg_replace ('/([a-za-z0-9_]+) \. ( [a-za-z0-9_*]+]/', function ($r) {  return $this->_getfieldtable ($r [1]). $r [2];  }, $fields);

Error
Object of class Closure could not being converted to string

Then you've already had an error.

$fields = Preg_replace_callback ('/([a-za-z0-9_]+) \. ( [a-za-z0-9_*]+]/', Array ($this, "_getfieldtable"), $fields);

But _getfieldtable to change it, because it is an array.

Attached source, God help me see

15,16 I use the xuzuning of the great God.

        $fields = Preg_replace ('/([a-za-z0-9_]+) \. ( [a-za-z0-9_*]+)/E ', "\ $this->_getfieldtable (' \\1 '). \\2 ' ", $fields);        $fields = Preg_replace_callback ('/([a-za-z0-9_]+) \. ( [a-za-z0-9_*]+]/', function ($r) {return $this->_getfieldtable ($r [1]). $r [2];}, $fields);           $fields = Preg_replace_callback ('/([a-za-z0-9_]+) \. ( [a-za-z0-9_*]+]/', function ($r) {return $this->_getfieldtable ($r (1). $r (2));}, $fields);        return $fields;

The combined query statement looks like this.

MySQL error[1054]: Unknown column ' User_privprivs ' in ' field list ' MySQL query:select user_privprivs, SSTORE_NAME,USER_PR ivuser_id,s.store_id from Ecm_store s left JOIN ecm_user_priv user_priv on s.store_id = user_priv.store_id WHERE user_priv . user_id in (' 1 ') ORDER by sstore_id DESC wrong File: \eccore\model\mysql.php[534]

It's supposed to be that way.

SELECT User_priv.privs, s.store_name,user_priv.user_id,s.store_id from Ecm_store s left joins Ecm_user_priv User_priv on S . store_id = user_priv.store_id WHERE user_priv.user_id in (' 1 ') ORDER by s.store_id DESC

The problem with the error is that User_priv.privs and user_priv.user_id and s.store_id focus on the reference "." None of them.

Oh, I missed a point.

$fields = Preg_replace ('/([a-za-z0-9_]+) \. ( [a-za-z0-9_*]+]/', function ($r) {  return $this->_getfieldtable ($r [1]). ". $r [2]";  }, $fields);

the last one, thank you xuzuning the great God. Preg_replace How to replace the last face

The only last pair that needs to be modified:

$source = Preg_replace_callback ('/{nocache} (. +?) {\/nocache}/is ', function ($r) {    return ' {Insert name= ' NoCache "'  . $this->_echash.  Base64_encode ($r [1]). '}'; }, $source);

Xu always give strength Ah,

    function Fetch_str ($source)    {        if (!defined (' is_backend '))        {            $source = $this->smarty_prefilter_ Precompile ($source);        }        Return Preg_replace ("/{([^\}\{\n]*)}/e", "\ $this->select (' \\1 ');", $source);    }

/E is eval ("return string")
You take off the outer quotes, you're right.

function ($r) {
return $this->select ($r [1]);
}
