sscanf
(PHP4 >= 4.0.1)
sscanf --- 依照格式剖析字符串
语法 :
mixed sscanf(string str, string format [, string var1...])说明 :
sscanf( )输入的参数和printf( )类似，sscanf( )读取字符串 str，并且依照指定的格式 format来解释它。如果只传递二个参数给此函数，则传回剖析后的值将会是个数组。
Example :
<?php
// getting the serial number
$serial = sscanf("SN/2350001","SN/%d");
// and the date of manufacturing
$mandate = "January 01 2000";
list($month, $day, $year) = sscanf($mandate,"%s %d %d");
echo "Item $serial was manufactured on: $year-".substr($month,0,3)."-$day\n";
?>
如果有传递非必需参数时，函数将会传回分配值的数目，非必需参数必须依照关系传递。
Example :
<?php
// get author info and generate DocBook entry
$auth = "24\tLewis Carroll";
$n = sscanf($auth,"%d\t%s %s", &$id, &$first, &$last);
echo "<author id='$id'> <firstname>$first</firstname> <surname>$last</surname> </author>\n";
?>
