I have a variable which value is supposed to be 'age'. I checked if the value of this variable is equal or not to 'age'. Result is not equal.

echo $this->param;  // returns 'age'

if('age' == $this->param) echo 'equal';  // returns false

It inputs only the text 'age'. Where is 'equal'?

What is going on?

post output of `var_dump($this->param)` please – Mahmoud Tantawy Jan 27 '16 at 19:40
Can you `var_dump($this->param)`? – ceejayoz Jan 27 '16 at 19:40

`var_dump($age, $this->param)`. you'll probably find that param is `age[space]` or something. – Marc B Jan 27 '16 at 19:40
Sometimes there is non meaningful broken utf-8 chars exist, when you try to print it doesn't show up but languages detects that when checking equality or any other process. – FZE Jan 27 '16 at 19:42
var_dump($this->param) returns string(9) "age" hmm..? – betty39johnson Jan 27 '16 at 19:43

Then you might have spaces, try to `trim()` before comparing – Mahmoud Tantawy Jan 27 '16 at 19:44
Try `if('age' == trim($this->param)) echo 'equal';` – Mahmoud Tantawy Jan 27 '16 at 19:45
If it returned `false` too then post output of `var_dump(trim($this->param))` to check if the issue is trimming or encoding. – Mahmoud Tantawy Jan 27 '16 at 19:45
The same result, returns string(9) "age". – betty39johnson Jan 27 '16 at 19:50
Weird! Check this to change encoding http://stackoverflow.com/questions/7979567/php-convert-any-string-to-utf-8-without-knowing-the-original-character-set-or and try to compare again – Mahmoud Tantawy Jan 27 '16 at 19:52
If it is string(9), you have got some leading/trailing whitespaces. trim () it. – Jan 27 '16 at 19:53
