PHP: Coerce / Convert boolean value to readable string format
Raw
boolean_to_string_format.php
<?//lsauer.com
//desc: 'false' converted into a string returns an empty string
// assert((string)$boolvariable == '', '"false" converted into a <string> does not return an empty string')
// assert((string)$boolvariable == '', '"true" converted into a <string> does not return "1"')
//related to: http://stackoverflow.com/questions/7336861/how-to-convert-string-to-boolean-php
//example
echo $boolvariable ? 'true' : 'false';
echo $arrayvariable['somkeyvaluelevel1']['somekeyvaluelevel2'] ? $arrayvariable['somkeyvaluelevel1']['somekeyvaluelevel2'] 'true' : 'false';
//using the ternary operator, does not yield a concise and readable solution:
//PHP provides var_export for that
printf("Hello variable, you seem to be: %s", var_export($boolvariable['somkeyvaluelevel1']['somekeyvaluelevel2'], true));
//additionally, filter_var can be repurposed
echo filter_var($boolvariable, FILTER_VALIDATE_BOOLEAN);
