To convert a string into a number, the code is as follows−
Example
<?php $str = "150"; $num = (int)$str; echo "Number (Converted from String) = $num"; ?>
Output
This will produce the following output−
Number (Converted from String) = 150
Example
Let us now see another example−
<?php $str = "100.56"; echo "String = $str"; $num = floatval($str); echo "\nNumber (Converted from String) = $num"; ?>
Output
This will produce the following output−
String = 100.56 Number (Converted from String) = 100.56
