A “For Loop” executes a block of code a specific number of times or while a specified condition is true.
PHP For Loop
for (init; condition; increment)
{
code to be executed;
}php fOR lOOP PARAMETERS
- init: Mostly used to set a counter (but can be any code to be executed once at the beginning of the loop)
- condition: Evaluated for each loop iteration. If it evaluates to TRUE, the loop continues. If it evaluates to FALSE, the loop ends.
- increment: Mostly used to increment a counter (but can be any code to be executed at the end of the iteration)
Note: The init and increment parameters above can be empty or have multiple expressions (separated by commas). Example The example below defines a loop that starts with i=1. The loop will continue to run as long as the variable i is less than, or equal to 5. The variable i will increase by 1 each time the loop runs:
PHP For Loop Example Code
<?php
for ($i=1; $i<=5; $i++)
{
echo("The number is " . $i . "<br>");
}
?>Classic ASP For Loop Example Code
<%
For i = 1 to 5
Response.Write("The number is " & i & "<br>")
Next
%>JavaScript For Loop Example
<%
For i = 1 to 5
Response.Write("The number is " & i & "<br>")
Next
%>C# For Loop Example
for (int i = 0; i < 5; i++)
{
Console.WriteLine(i);
} Python For Loop Example
states = ["Alaska", "Alabama", "Arkansas"]
for x in states:
print(x)
if x == "Alabama":
break
