Convert a string containing a number in scientific notation to a normal string in PHP

Question

I need help converting a string that contains a number in scientific notation to a normal string. Example strings: "9.1892E+11" to "918919850755"

I used some predefined functions like : number_format, dechex etc. but not getting exact value. — Mohit Tiwari, Oct 27 '18 at 11:28
@MadhurBhaiya thanks for quick response but number is 918919850755. Scientific string generated from csv cell. — Mohit Tiwari, Oct 27 '18 at 11:29

PHP should understand the scientific notation. By substracting or adding 0 or something, it will change to a normal notation.

By doing this you might lose precision. You can cast the string to a float to prevent this.

$number = (float)$number;

The value displayes in the cell is excels visual representation of the value in the bar (and the cells actual value), but they're not the same. – DigiLive Oct 27 '18 at 11:58
I didn't get any thing from you my friend. – Mohit Tiwari Oct 29 '18 at 04:28
I just need "918919850755" in the output. – Mohit Tiwari Oct 29 '18 at 04:29
