正则表达式，删除PHP中除一个字符外的所有字符

Question

I need your help.

I need to remove a pattern from a text file ,"refresh":18});

But I don't need to delete curly bracket in this pattern, I need to save it.

My code

...
echo $data2 = str_replace(",\"refresh\":18});", "", $data);
...

How to change my regex to remove the pattern, but don not remove } charecter ?

Answer 1

Why don't you just replace the whole pattern with character '}' ??? Just try:

echo str_replace(",\"refresh\":18});", "}", $data);
