SHIFT()¶

Synopsis¶

Removes and returns the first item off of a variable containing delimited text

Description¶

Example: SHIFT example

exten => s,1,Set(array=one,two,three)
exten => s,n,While($["${SET(var=${SHIFT(array)})}" != ""])
exten => s,n,NoOp(var is ${var})
exten => s,n,EndWhile

This would iterate over each value in array, left to right, and would result in NoOp(var is one), NoOp(var is two), and NoOp(var is three) being executed.

Syntax¶

SHIFT(varname[,delimiter])

Arguments¶

varname
delimiter
