blocks|key|1880240|text|我的建议是将分数放在一个数组中，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1880241|$scores+=+array(1,+2,+4,+5);
$highest+=+max($scores);
$lowest+=+min($scores);|code-block|syntax|javascript|1880242|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

<p>My suggestion is to put the scores in an array, like so:</p>

<pre><code>$scores = array(1, 2, 4, 5);
$highest = max($scores);
$lowest = min($scores);
</code></pre>


blocks|key|1562858|text|当您比较一个值列表时，最好将它们存储在数组中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1562859|试试这个：|1562860|$val1+=+10;
$val2+=+20;
$val3+=+30;
$val4+=+40;
$val5+=+50;

$arr+=+compact('val1','val2','val3','val4','val5');++//+Stores+values+in+array+$arr
$highval+=+max($arr);+//+50
$lowval++=+min($arr);++//+10|code-block|syntax|javascript|1562861|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

<p>When you are comparing a list of values, it's the best to store them in an array.</p>

<p>Try this:</p>

<pre><code>$val1 = 10;
$val2 = 20;
$val3 = 30;
$val4 = 40;
$val5 = 50;

$arr = compact('val1','val2','val3','val4','val5');  // Stores values in array $arr
$highval = max($arr); // 50
$lowval  = min($arr);  // 10
</code></pre>

<p>well maybe you already find the solution ...</p>

<p>variables must not include numbers like your example</p>

<pre class="lang-php prettyprint-override"><code>$val1 = 10;
$val2 = 20;
$val3 = 30;
$val4 = 40;
$val5 = 50;

$arr = compact('val1 ', 'val2 ', 'val3 ', 'val4 ', 'val5 ');
$highval = max($arr);
$lowval = min($arr);
</code></pre>

<pre class="lang-php prettyprint-override"><code>echo "$lowval"; //  give val1 the first variable value In brackets inside
echo "$highval"; // give val5 the last variable value In brackets inside
</code></pre>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>lowval  is val1 (10)
highval is val5 (50)
The above example will give correct results 
(you got the right results because it happened 
to have the values ​​in ascending order).
WHY IS THIS WRONG !!! 
see below</code></pre>
</div>
</div>
</p>

<p>PLEASE NOTE
If the data comes from a database or an xml file then the values ​​are dynamic and not ascending, in this case we will get back the wrong results.</p>



<pre><code>$val1 = 20;
$val2 = 30;
$val3 = 10;
$val4 = 50;
$val5 = 40;

$arr = compact('val1 ', 'val2 ', 'val3 ', 'val4 ', 'val5 ');
$highval = max($arr);
$lowval = min($arr);
</code></pre>



<pre><code> echo"$lowval"; // val1 give the first variable value In brackets inside
 echo"$highval"; // val5 give the last variable value In brackets inside
</code></pre>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>The above example will give wrong results 
lowval is val1 (20)
highval isval5 (40)
The right results are
lowval=val3 (10)
highval=val4 (50)</code></pre>
</div>
</div>
</p>

<p>A simple solution is to replace the numbers with letters</p>



<pre><code>$val1 = 30;
$val2 = 10;
$val3 = 50;
$val4 = 40;
$val5 = 20;

$vala = "$val1";
$valb = "$val2";
$valc = "$val3";
$vald = "$val4";
$vale = "$val5";

$arr = compact('vala ', 'valb ', 'valc ', 'vald ', 'vale ');
$highval = max($arr);
$lowval = min($arr);
</code></pre>

<p>now the results is correct</p>

<pre class="lang-php prettyprint-override"><code> echo "$lowval"; // give valb the lower value
 echo "$highval"; // give valc the higher value
</code></pre>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>Now the results is correct 
lowval is valb (10)
highval is valc (50)</code></pre>
</div>
</div>
</p>


<p>Is their any way to get the highest and lowest value among variables?</p>

<p>example is that i have this variables</p>

<pre><code>$val1 = 10
 $val2 = 20
 $val3 = 30
 $val4 = 40
 $val5 = 50
</code></pre>

<p>and among this variable i want to display or put to another variable the variable that has the highest and lowest value. just like below.</p>

<pre><code>$highval = $val5; 
$lowval = $val1;
</code></pre>

<p><code>$val5</code> in <code>$highval</code> coz it has the value of 50
and
<code>$val1</code> in <code>$lowval</code> coz it has the value of 10 .</p>

<p>thanks</p>
