PHP two date handler for SQL Server simulation _php Tutorial

Working with dates in PHP is inconvenient, such as finding a month between two dates? 　　What should we do? 　　File name: DATE.INC.PHP3//Before using these two functions, convert the date or datetime to the timestamp type. 　　such as://$today =mktime (0,0,0,date ("M"), Date ("D"), Date ("Y")); /**** simulates the DATEADD function in SQL Server ******* $part Type: String value range: Year,month,day,hour,min,sec represents: Which part of the date to increase $n type: Numeric representation: To How much increases, depending on $part decide which part can be negative $datetime type: Timestamp: Added cardinality return type: Timestamp ************** end **************/Functio n DateAdd ($part, $n, $datetime) {$year =date ("Y", $datetime), $month =date ("M", $datetime); $day =date ("D", $datetime); $ Hour=date ("H", $datetime); $min =date ("i", $datetime); $sec =date ("s", $datetime); $part =strtolower ($part); $ret = 0; Switch ($part) {case ' year ': $year + = $n, break, case ' month ': $month + = $n, break, Case ' Day ': $day + = $n, break, Case "hour": $hour + = $n; Break Case "min": $min + = $n; Break Case "SEC": $sec + = $n; Break Default:return $ret; Break } $ret =mktime ($hour, $min, $sec, $month, $day, $year); return $ret; }/**** simulates the DATEDIFF function in SQL Server ******* $part Type: String value range: Year,montH,day,hour,min,sec says: Which part of the date to increase $date 1, $date 2 type: Timestamp: Two date return type to compare: Value ************** End * (************ */function DateDiff ($part, $date 1, $date 2) {//$diff = $date 2-$date 1; $year 1=date ("Y", $date 1), $year 2=date ("Y", $date 2); $month 2=date ("M", $date 2); $month 1=date ("M", $date 1); $day 2=date ("D", $date 2); $day 1=date ("D", $date 1); $hour 2=date ("D", $date 2); $hour 1=date ("D", $date 1); $min 2=date ("i", $date 2); $min 1=date ("i", $date 1); $sec 2=date ("s", $date 2); $sec 1=date ("s", $date 1); $part =strtolower ($part); $ret = 0; Switch ($part) {case ' year ': $ret = $year 2-$year 1; break, case ' month ': $ret = ($year 2-$year 1) *12+ $month 2-$month 1; break; CA Se "Day": $ret = (Mktime (0,0,0, $month 2, $day 2, $year 2)-mktime (0,0,0, $month 1, $day 1, $year 1))/(3600*24); Break Case "Hour": $ret = (mktime ($hour 2,0,0, $month 2, $day 2, $year 2)-mktime ($hour 1,0,0, $month 1, $day 1, $year 1))/3600; Break Case "min": $ret = (Mktime ($hour 2, $min 2,0, $month 2, $day 2, $year 2)-mktime ($hour 1, $min 1,0, $month 1, $day 1, $year 1))/60; Break Case "SEC": $ret = $date 2-$date1; Break Default:return $ret; Break } return $ret; } }
