PHP - convert string to float

Question

I need to convert String to Float.

I will get the lines as follows:

$string = "1.70 m"; $string2 = "2.445 m"; 

How can you easily convert these lines to:

 $float1 = 1.70; $float2 = 2.445; 

Can someone give me some clues?

Best wishes,

Answer 1

These are floats , not integers . Integers do not have decimal points.

To answer your question, you can simply typecast strings directly, the conversion will disable units, since they are not numeric characters:

 $string = "1.70 m"; $float = (float) $string; 

Answer 2

you can get it

 echo (float)array_shift(implode(' ', $string)); 

Update:

 echo (float) $string; 

Answer 3

The easiest way to do this is probably using the floatval () function:

For exmaple:

 floatval("1.70 m"); 

gives you:

1.7

Answer 4

 $integer = intval($string);
