StringTrimLeft
删除字符串中从左开始指定数量的字符。
StringTrimLeft ( "字符串", 数量 )
参数
| 字符串 | 目标字符串。 |
| 数量 | 要删除的字符数。 |
返回值
返回从左开始指定数量字符被删去后的字符串。注意
若给定的数量越界则返回一个空字符串。StringTrimLeft($str, $n) 的作用等价于 StringRight($str, StringLen($str) - $n)
相关
String, StringInStr, StringLeft, StringLen, StringLower, StringMid, StringRight, StringTrimRight, StringUpper示例
