PHP: Tips of the Day
var_export(): var_export() dumps a PHP parseable representation of the item.
You can pass true as the second parameter to return the contents into a variable.
Example:
<?php $myarray = [ "PHP", "Tips" ]; $mystring = "PHP Tips"; $myint = 28; var_export($myarray); var_export($mystring); var_export($myint); ?>
Output:
array ( 0 => 'PHP', 1 => 'Tips', )'PHP Tips'28
To put the content into a variable, you can do this:
$array_export = var_export($myarray, true); $string_export = var_export($mystring, true); $int_export = var_export($myint, 1); // any `Truthy` value
After that, you can output it like this:
printf('$myarray = %s; %s', $array_export, PHP_EOL); printf('$mystring = %s; %s', $string_export, PHP_EOL); printf('$myint = %s; %s', $int_export, PHP_EOL);
Example:
<?php $myarray = [ "PHP", "Tips" ]; $mystring = "PHP Tips"; $myint = 28; $array_export = var_export($myarray, true); $string_export = var_export($mystring, true); $int_export = var_export($myint, 1); printf('$myarray = %s; %s', $array_export, PHP_EOL); printf('$mystring = %s; %s', $string_export, PHP_EOL); printf('$myint = %s; %s', $int_export, PHP_EOL); ?>
This will produce the following output:
Output:
$myarray = array ( 0 => 'PHP', 1 => 'Tips', ); $mystring = 'PHP Tips'; $myint = 28;
