<br />
<br />

<br />
In this case, the condition is '''i is less than or equal to 4'''.<br />
<br />
<br />
If this condition is true, the code within the curly bracket will be executed.<br />
<br />
|-<br />
| style="border-top:none;border-bottom:0.05pt solid #000000;border-left:0.05pt solid #000000;border-right:none;padding:0.097cm;"| Highlight '''print'''<br />

<br />
'''“Value of i: 0”'''<br />
<br />
will be displayed on the '''terminal'''.<br />
<br />
|-<br />
| style="border-top:none;border-bottom:0.05pt solid #000000;border-left:0.05pt solid #000000;border-right:none;padding:0.097cm;"| Highlight '''$i++'''<br />

<br />
|-<br />

<br />
<br />
This loop will exit when the value of''' i''' becomes greater than '''4'''.<br />
<br />
|-<br />
| style="border-top:none;border-bottom:0.05pt solid #000000;border-left:0.05pt solid #000000;border-right:none;padding:0.097cm;"| <br />

<br />
<br />
An array '''myarray '''is declared. <br />
<br />
It has 3 elements 10, 20 and 30.<br />
<br />
|-<br />

<br />
<br />
Then 20 and so on, till all the elements are printed.<br />
<br />
|-<br />
| style="border-top:none;border-bottom:0.05pt solid #000000;border-left:0.05pt solid #000000;border-right:none;padding:0.097cm;"| Highlight '''foreach '''<br />
