php array_sum函数统计数组和值 php数组求和

今天手机突然停机了,端午节从家里过来的时候还有20多块钱的,也没怎么打电话,就被联通给欠费了.遂上网查话费清单,竟然没有统计项目,于是自己就用php array_sum函数统计了下话费合计,果然是扣光了.郁闷.
数组如下:

array(43) {
[0]=>
string(6) "0.00
"
[1]=>
string(6) "0.00
"
[2]=>
string(6) "0.00
"
[3]=>
string(6) "0.00
"
[4]=>
string(6) "0.50
"
[5]=>
string(6) "0.75
"
[6]=>
string(6) "0.00
"
[7]=>
string(6) "0.00
"
[8]=>
string(6) "0.50
"
[9]=>
string(6) "2.25
"
[10]=>
string(6) "0.00
"
[11]=>
string(6) "0.50
"
[12]=>
string(6) "1.25
"
[13]=>
string(6) "1.00

[28]=>

[29]=>
string(6) "0.50
"
[30]=>
string(6) "0.50
"
[31]=>
string(6) "0.00
"
[32]=>
string(6) "0.25
"
[33]=>
string(6) "0.00
"
[34]=>
string(6) "0.00
"
[35]=>
string(6) "0.60
"
[36]=>
string(6) "0.60
"
[37]=>
string(6) "0.00
"
[38]=>
string(6) "0.75
"
[39]=>
string(6) "0.00
"
[40]=>
string(6) "0.00
"
[41]=>
string(6) "0.00
"
[42]=>
string(4) "0.00"
}


从excel里复制来的一个字符串,然后切分的数组.
数字名 $total ; echo array_sum($total); 算出来了.
php函数还是挺多的,手册要经常啃啊.
