Question
Are these functions the same? If not, what is an appropriate php equivalent to mysql's radians()
Solution
Judging from their documentations (deg2rad
, radians
), they seem to do the same.
And a quick verification on a simple test-case :
mysql> select radians(0), radians(45), radians(90);
+------------+-------------------+-----------------+
| radians(0) | radians(45) | radians(90) |
+------------+-------------------+-----------------+
| 0 | 0.785398163397448 | 1.5707963267949 |
+------------+-------------------+-----------------+
1 row in set (0,00 sec)
And, in PHP :
var_dump(deg2rad(0), deg2rad(45), deg2rad(90));
also gives :
float 0
float 0.785398163397
float 1.57079632679
So, it seems they do quite the same...
OTHER TIPS
Consulting the documentation:
- MySQL's RADIANS(x): returns the argument
x
, converted from degrees to radians. - PHP's DEG2RAD(): converts the number in degrees to the radian equivalent
...so yes, they are equivalent.
