comparison in php using == and === operators -

-

In my application, values ​​like x, 1x, 2,1 etc. are created when running. I need to compare these:

As we know, 

  x == 1 is false '1x' == 1 true '1' = = 1 is true

For my application, first, other matters should be false and the third needs to be correct. If I use ===, then 

  x === 1 is wrong '1x' === 1 is false 1 '=== 1 is false  < / Pre> 
 So I can not compare these two 
 
 I think converting it into a string and then using  strcmp  would be the best option for me. Please share your thoughts Any answers are appreciated.

strcmp would be appropriate for this. But you should be aware of its return values

Returns & lt; 0 if str1 is less than str2; & Gt; 0 If str1 is larger than str2, and 0 if they are equal

Or you can also use Regex

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
