Now, my problem is that most of the lines in the file... (3 Replies)

DESCRIPTION

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:

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.
