PHP | IntlChar getIntPropertyValue() Function

The IntlChar::getIntPropertyValue() function is an inbuilt function in PHP which is used to get the value for Unicode property for a code point.
Syntax:

int IntlChar::getIntPropertyValue( $codepoint, $property )

Parameter: This function accepts two parameters as mentioned above and described below: 

• $codepoint: The input parameter $codepoint is a character or integer value, which is encoded as a UTF-8 string.
• $property It store the unicode character constant. Example: IntlChar::PROPERTY_* constants.

Return Values:

• It returns the numeric value which is directly the property value or, enumerated properties, corresponds to the numeric value of the enumerated constant of the respective property value enumeration type.
• It returns the boolean value (0/1 or FALSE/TRUE) for binary Unicode properties.
• It returns the bit-mask value for mask properties.
• It returns 0 if the property is out of bounds or if the Unicode version does not have data for the property at all, or not for this code point.

Below programs illustrate the IntlChar::getIntPropertyValue() function in PHP:
Program 1:

php

<?php

// Input data is alphabet character type
var_dump(IntlChar::getIntPropertyValue("A",
        IntlChar::PROPERTY_ALPHABETIC) === 1);

// Input data is mirrored brackets character type
var_dump(IntlChar::getIntPropertyValue("[",
        IntlChar::PROPERTY_BIDI_MIRRORED) === 1);

// Input data is Space character type
var_dump(IntlChar::getIntPropertyValue(" ",
        IntlChar::PROPERTY_POSIX_BLANK) === 1);

// Input data is special character type
var_dump(IntlChar::getIntPropertyValue("?",
    IntlChar::PROPERTY_BLOCK) === IntlChar::BLOCK_CODE_GREEK);

?>

Output:

bool(true)
bool(true)
bool(true)
bool(false)

Program 2:

php

<?php

// Input data is alphabet character type
var_dump(IntlChar::getIntPropertyValue("A",
        IntlChar::PROPERTY_ALPHABETIC) === 1);

// Input data is special character type
var_dump(IntlChar::getIntPropertyValue("|",
        IntlChar::PROPERTY_BIDI_MIRRORED) === 1);

// Input data is special character type
var_dump(IntlChar::getIntPropertyValue("?",
    IntlChar::PROPERTY_BLOCK) === IntlChar::BLOCK_CODE_GREEK);

// Input data is numeric character type
var_dump(IntlChar::getIntPropertyValue("9",
        IntlChar::PROPERTY_NUMERIC_TYPE) === 1 );

// Input data is math character type
var_dump(IntlChar::getIntPropertyValue("=",
        IntlChar::PROPERTY_MATH) === 1 );

?>

Output:

bool(true)
bool(false)
bool(false)
bool(true)
bool(true)
