SYNOPSIS
bool ctype_space (string $text) DESCRIPTION
Checks if all of the characters in the provided string, $text, creates whitespace. PARAMETERS
o $text - The tested string. RETURN VALUES
Returns TRUE if every character in $text creates some sort of white space, FALSE otherwise. Besides the blank character this also includes tab, vertical tab, line feed, carriage return and form feed characters. EXAMPLES
Example #1 A ctype_space(3) example <?php $strings = array('string1' => " ", 'string2' => " arf12", 'string3' => ' '); foreach ($strings as $name => $testcase) { if (ctype_space($testcase)) { echo "The string '$name' consists of all whitespace characters. "; } else { echo "The string '$name' does not consist of all whitespace characters. "; } } ?> The above example will output: The string 'string1' consists of all whitespace characters. The string 'string2' does not consist of all whitespace characters. The string 'string3' does not consist of all whitespace characters. NOTES
Note If an integer between -128 and 255 inclusive is provided, it is interpreted as the ASCII value of a single character (negative val- ues have 256 added in order to allow characters in the Extended ASCII range). Any other integer is interpreted as a string contain- ing the decimal digits of the integer. SEE ALSO
