smart flash recovery php Smarty 字元比較代碼

eq相等，
ne、neq不相等，
gt大於，
lt小於，
gte、ge大於等於，
lte、le 小於等於，
not非， mod求模。
is [not] div by是否能被某數整除，
is [not] even是否為偶數，
$a is [not] even by $b即($a / $b) % 2 == 0，
is [not] odd是否為奇，
$a is not odd by $b即($a / $b) % 2 != 0 例：
equal/ not equal / greater than/ less than/ less than or equal/ great than or equal/後面的就不用說了
Smarty 中的if 語句和php 中的if 語句一樣靈活易用，並增加了幾個特性以適宜模板引擎. if 必須於/if 成對出現. 可以使用else 和elseif 子句. 可以使用以下條件修飾詞：eq、ne、neq、gt、lt、lte、le、gte、ge、is even、is odd 、is not even、is not odd、not、mod、div by、even by、odd by、==、!=、>、=. 使用這些修飾詞時必須和變數或常數用空格格開.
