我需要做一个简单的正则表达式查找，并用PHP替换我的PHP语法突出显示脚本.
I need to do a simple regex find and replace with PHP for my syntax highlighting script in PHP.
我需要采用一串代码，实际上这将是一个完整的php文件，并被读取为这样的字符串.
I need to take a string of code which will actually be a whole php file that is read into a string like this.
$code_string = 'the whole source code of a php file will be held in this string';然后找到所有出现的情况并进行替换...
And then find all occurences of these and do a replace...
查找: [php] 并替换为 <pre class="brush: php;"> 查找: [/php] 并替换为 </pre>
Find: [php] and replace with <pre class="brush: php;"> Find: [/php] and replace with </pre>
找到 [javascript] 并替换为 <pre class="brush: js;"> 查找: [/javascript] 并替换为 </pre>
Find [javascript] and replace with <pre class="brush: js;"> Find: [/javascript] and replace with </pre>
我真的对正则表达式不好，有人可以帮我吗?
I really am not good with regex could someone please help me with this?
推荐答案要替换字符串中的字符串，您只需str_replace();.如果我正确理解了您的问题，它将看起来像这样:
For the replacement of strings within strings you can just str_replace();. If I understand your question correctly it would look something like this:
$code_string = htmlentities(file_get_contents("file.php")); $old = array("[php]","[javascript]","[/php]","[/javascript]"); $new = array('<pre class="brush: php;">','<pre class="brush: js;">','</pre>','</pre>'); $new_code_string = str_replace($old,$new,$code_string); echo $new_code_string;
