With printf() and sprintf() functions, escape character is not backslash '\' but rather '%'. I am %my_age%, how old are you? This is because any sequence of white-space is treated as a single space.//The variation that prints the string instead of returning it: This is not a bug; sensitive information (ex. However, I wasn't completely satisfied with Matt's code (sorry, Matt! Unfortunately this is only applicable if that variable is one of the following types: Boolean – A Boolean value TRUE is converted to string “1” whereas Boolean FALSE is converted to an empty string “” I like %object!

@DoomStone I know it's been 3 years, but I just wanted to know what makes you think in some cases it's not the best solution. sprintf against PHP string concatenation operator.
A conversion specification follows this prototype: [1-9][0-9]*|)([%a-zA-Z])!u"// didn't match. Attempting to use a position specifier greater than
Free 30 Day Trial I am %my_age, how old are you? If you use the default padding specifier (a space) and then print it to HTML, you will notice that HTML does not display the multiple spaces correctly. If you want to convert a decimal (integer) number into constant length binary number in lets say 9 bits, use this: For example:
''Hello %your_name%, my name is %my_name%! It also relies on the JSON extension being installed and enabled, which might be very likely but isn't a given.
I like %object% and I want to %objective_in_life%!
Test was performed on PHP 7.3 for 1 million interations. It should work with any "ASCII preserving" encoding such as UTF-8 and all the ISO-8859 charsets. up. If you are not sure about the type you are dealing with, you have a whole other set of problems to begin with.Note that you need extra brackets when you mix ternary operator and string concatenation.
"select * from %1\$s left join %2\$s on( %1\$s.id = %2\$s.midpoint ) where %1\$s.name like '%%%s%%' and %2\$s.tagname is not null""select * from %1\$s left join %2\$s on( %1\$s.id = %2\$s.midpoint ) where %1\$s.name like '%%%3\$s%%' and %2\$s.tagname is not null" We would write the format string like this instead: Returns a string produced according to the formatting string The documentation incorrectly states that they are interchangeable.
If you are (1) looping over mixed-types or (2) want a generic solution that you can export as a function or include in your utilities, none of the other solutions here will work.The simplest and most self-explanatory solution is:But most developers reading your code will require a trip to Works for boolean input but converts everything else (ints, strings) to true/false.For me, I wanted a string representation unless it was Short and simple and easy to throw in a function too if you prefer.As a solution, I have used type casting to ensure that we convert To avoid repetition, the array containing the string representation of the Boolean can be stored in a constant that can be made available throughout the application.I'm not a fan of the accepted answer as it converts anything which evaluates to false to To subscribe to this RSS feed, copy and paste this URL into your RSS reader.
I am 21, how old are you? I had a nightmare trying to find the two's complement of a 32 bit number. There is a minor issue in a code of mb_vsprintf function from viktor at textalk dot com. Here is an example how alignment, padding and precision specifier can be used to print formatted list of items: code. This is the "PHP" way of getting a "...a parsable string representation of a variable"This really relies on the side-effect that the JSON representation happens to be the same as what is wanted.
