php通过array_shift()函数移除数组第一个元素的方法，array_shift移除
本文实例讲述了php通过array_shift()函数移除数组第一个元素的方法。分享给大家供大家参考。具体分析如下：
下面的代码通过array_shift()函数加while循环不断移除数组的第一个元素，直到数组为空
<?php
$alpha = array("a", "b", "c");
while ( count( $alpha ) ) {
$val = array_shift( $alpha);
print "$val<br />";
print "there are ".count( $alpha )." elements in \$alpha <br />";
}
?>
希望本文所述对大家的php程序设计有所帮助。
