如何用PHP爆炸两个变量

Question

I was expecting that the explode function of the following string

$lines[1]="Start_time= ". $ST. ':' . $STIMI."
" ;

would give me Array[0]= Start_time, Array[1]= $ST, Array[2]= :, Array [3]= $STIMI

But the explode function gives me: Array[0]= Start_time Array[1]= $ST:$STIMI

$ST and $STIMI are both variables. Any idea how to fix this

Answer 1

The explode function takes a parameter by which to explode the string. Presuming you are using a blank space you will need to add a blank space on either side of your colon.

$lines[1]="Start_time= ". $ST. ' : ' . $STIMI."
" ;
