PHP String to Float

Question

I am not familiar with PHP at all and had a quick question   I have 2 variables pricePerUnit and InvoicedUnits  Here s the code that is setting these to values    InvoicedUnits     string   InvoiceLineItem- gt InvoicedUnits    pricePerUnit     string   InvoiceLineItem- gt PricePerUnit     If I output this  I get the correct values  Lets say 5000 invoiced units and 1 00 for price   Now  I need to show the total amount spent  When I multiply these two together it doesn t work  as expected  these are strings    But I have no clue how to parse cast convert variables in PHP   What should I do

Dealing with markup in floats is a non trivial task. In the English/American notation you format one thousand plus 46*10-2:

1,000.46

But in Germany you would change comma and point:

1.000,46

This makes it really hard guessing the right number in multi-language applications.
I strongly suggest using Zend_Measure of the Zend Framework for this task. This component will parse the string to a float by the users language.

Well  if user write 1 00 000 then floatvar will show error  So -   floatval preg replace     -0-9          input      This is much more reliable   Usage      input    1 03 24 23 434 500 6798633 this   echo floatval preg replace     -0-9          input

You want the non-locale-aware floatval function      float floatval    mixed  var    - Gets the float value of a string    Example    string    122 34343The    float    floatval  string   echo  float     122 34343

Use this function to cast a float value from any kind of text style   function parseFloat  value        return floatval preg replace      -   0-9                  1   0-9-  1 3      e    str replace array                               1         4     value        This solution is not dependant on any locale settings  Thus for user input users can type float values in any way they like  This is really helpful e g  when you have a project wich is in english only but people all over the world are using it and might not have in mind that the project wants a dot instead of a comma for float values  You could throw javascript in the mix and fetch the browsers default settings but still many people set these values to english but still typing 1 25 instead of 1 25  especially but not limited to the translation industry  research and IT

If you need to handle values that cannot be converted separately  you can use this method   try        valueToUse   trim  stringThatMightBeNumeric    0    catch   Throwable  th           bail here if you need to
