Return a formatted string (original) (raw)

%

A literal percent character. No argument is required.

b

The argument is treated as an integer and presented as a binary number.

c

The argument is treated as an integer and presented as the character with that ASCII.

d

The argument is treated as an integer and presented as a (signed) decimal number.

e

The argument is treated as scientific notation (e.g. 1.2e+2). The precision specifier stands for the number of digits after the decimal point since PHP 5.2.1. In earlier versions, it was taken as number of significant digits (one less).

E

Like the e specifier but uses uppercase letter (e.g. 1.2E+2).

f

The argument is treated as a float and presented as a floating-point number (locale aware).

F

The argument is treated as a float and presented as a floating-point number (non-locale aware). Available as of PHP 5.0.3.

g

General format.

Let P equal the precision if nonzero, 6 if the precision is omitted, or 1 if the precision is zero. Then, if a conversion with style E would have an exponent of X:

If P > X ≥ −4, the conversion is with style f and precision P − (X + 1). Otherwise, the conversion is with style e and precision P − 1.

G

Like the g specifier but usesE and f.

o

The argument is treated as an integer and presented as an octal number.

s

The argument is treated and presented as a string.

u

The argument is treated as an integer and presented as an unsigned decimal number.

x

The argument is treated as an integer and presented as a hexadecimal number (with lowercase letters).

X

The argument is treated as an integer and presented as a hexadecimal number (with uppercase letters).
