Conversion of string value in an array to float in php

Question

Hello friends I have two arrays called

var $conversion_rates;

and

var $LastUpdate_rates;

now I am updating them in my class with values . If you do var_dump() both of them you get values like this

 echo "This is conversion rates<br>".var_dump( $this->conversion_rates = $rates_array);

array(1) { [11]=> float(507.6) } This is conversion rates

echo "This is conversion rates<br>".var_dump($this->LastUpdate_rates = $this->checkRatesFile());

array(1) { [11]=> string(6) "507.60" } This is LastUpdate Rates

Then I am trying to do is this

if( count(array_diff($this->conversion_rates, $this->LastUpdate_rates)) >0){
       //do something ......
}

The if statement is always true because the array value are different so I want to change one of the array to float what should I do

Directly comparing floats with (essentially) $float1 == $float2 is very prone to errors due to float (in)accuracy to begin with. A simple array_diff will probably never get you there. — deceze

On a side note, var_dump() doesn't return a string, it writes directly to stdout. If you want it to get a string from it you'll have to use ob. (check php doc of ob_start()) — Loïc

Try this

$a = "0.275";
var_dump($a);

Then try this;

$a = "0.275";
var_dump((float)$a);

And see what you can make of that;
