\\\\\/]代わりにこのプットをテストします\\\\/]

$p5p6patterns = array(
        "/(\d{2,3}(?:[\.,]\d)?)[\\\\\/](\d{2,2}(?:[\.,]\d)?)\D/ui", //62.2/43.2  43/34 34\23
        "/(\d{2,3}(?:[\.,] ?\d)?)[\\\\\/](\d{2,2}(?:[\.,] ?\d)?)\D/ui", // 51, 2/30, 5/11, 8
        "/\D(\d{2,3}(?:[\.,]\d)?) ?[\\\\\/] ?(\d{2,2}(?:[\.,]\d)?)\D/ui", //62.2 / 43.2 / 7.4
        "/Общая\sплощадь\s\-\s(\d{1,2}(?:[\.,]?\d)?)\sкв\.м\.\sжилая\s\-\s(\d{1,2}(?:[\.,]?\d)?)\sкв\.м\./ui"// Общая площадь - 74.6 кв.м. жилая - 29.8 кв.м.
    );

preg_match_all()配列としてパターンを与えませんでした

int preg_match_all ( string $pattern , string $subject [, array &$matches [, int $flags = PREG_PATTERN_ORDER [, int $offset = 0 ]]] )
