How do I break a for-loop in PHP when conditions are met?
提问by Alex Mcp
I'm diligently plugging away at some code that checks for divisibility (yes, it's to generate primes) and I want to know how to stop a for... loop if the condition is met once. Code like this:
我正在努力编写一些检查可分性的代码（是的，它是为了生成素数），我想知道如果条件满足一次，如何停止 for... 循环。像这样的代码：
$delete = array();
foreach ( $testarray as $v ) {
for ( $b = 2; $b < $v; $b++ ) {
if ( $v % $b == 0 ) {
$delete []= $v;
}
}
So $testarrayis integers 1-100, and the $deletearray will be filtered against the $testarray. Currently though, a number like 12 is being added to $deletemultiple times because it's divisible by 2, 3, 4, and 6. How can I save my computer's time by skipping ahead when the criteria matched once?
所以$testarray是整数1-100，和$delete数组将针对被过滤$testarray。但目前，像 12 这样的数字被$delete多次添加，因为它可以被 2、3、4 和 6 整除。当条件匹配一次时，我如何通过跳过来节省计算机的时间？

break; #breaks out of a loop
continue; #skips rest of current iteration
