preg-replace-callback

问题 My function now only works with one word. For example, I have words in an associative array. And my function replaces the array key with its value in the text. And the function to keep the words in the lower case, but when you replace words it will return the incoming word register that is written on the text.

问题 This code: $t = 100; $str = preg_replace_callback("/(Name[A-Z]+[0-9]*)/", create_function( '$matches', 'return $matches[1] + $t;' ), $func); How to make $t visible from create_function() in preg_replace() function? 回答1: An anonymous function would work, while making use of the use syntax: $t = 100; $str = preg_replace_callback("/(Name[A-Z]+[0-9]*)/", function($matches) use($t) // $t will now be visible inside of the function { return $matches[1] + $t; }, $func); 回答2: You can't make the

问题 I have a question for you! Normally, if you call a callback function within an OOP context you have to use array(&$this, 'callback_function') That's what I figured out. But now I want to call a callback in an external class, due to having to much callback_functions. I want to give them an own class for structure reasons. I thought: "Ok, make an instance of this class and pass it instead of $this." So I tried it with array($cb, 'callback_function') and array($this->cb, 'callback_function') but

问题 I have the following HTML statement [otsection]Wallpapers[/otsection] WALLPAPERS GO HERE [otsection]Videos[/otsection] VIDEOS GO HERE What I am trying to do is replace the [otsection] tags with an html div. The catch is I want to increment the id of the div from 1->2->3, etc..

问题 I'm terrible with regular expressions. I'm trying to replace this: public static function camelize($word) { return preg_replace('/(^|_)([a-z])/e', 'strtoupper("\\2")', $word); } with preg_replace_callback with an anonymous function. I don't understand what the \\2 is doing. Or for that matter exactly how preg_replace_callback works. What would be the correct code for achieving this? 回答1: In a regular expression, you can "capture" parts of the matched string with (brackets) ; in this case, you
