A simple example of using php for loop, phpfor loop example

The for loop is used when you know in advance the number of times the script needs to run.

Grammar

for (初始值; 条件; 增量) 
{ 
要执行的代码; 
} 

Parameters:

•Initial value: Mainly initializes a variable value, used to set a counter (but can be any code that is executed once at the beginning of the loop).

•Conditions: Restrictions on loop execution. If TRUE, the loop continues. If FALSE, the loop ends.

• Increment: is mainly used to increment a counter (but can be any code that is executed at the end of the loop).

Note: The above initial value and increment parameters can be empty, or have multiple expressions (separated by commas).

The following example defines a loop with an initial value of i=1. As long as variable i is less than or equal to 5, the loop will continue to run. Each time the loop runs, the variable i will be incremented by 1:

<&#63;php 
for ($i=1; $i<=5; $i++) 
{ 
echo "The number is " . $i . "<br>"; 
} 
&#63;> 

Output:

The number is 1 
The number is 2 
The number is 3 
The number is 4 
The number is 5
