多次回显PHP变量

Question

How would one go about echoing a variable multiple times..

A way to understand this question better would be if I said:

$foo = '<div>bar</div>';
echo $foo*7;

It's probably the most simple thing, but I'm not sure.

And

Answer 1

In this simple case, you can use str_repeat() .

$foo = '<div>bar</div>';
echo str_repeat($foo, 7);

Reference: PHP string functions

For anything more complex, a loop is usually the way to go.

Answer 2

Don't multiply strings. You can either do it manually:

echo $variable;
echo $variable;
echo $variable;
echo $variable;
// etc

Or in a for loop:

for($z=0;$z<10;$z++){
  echo $variable;
}

Or str_repeat:

echo str_repeat($variable, 10);

Answer 3

使用str_repeat() 。

echo str_repeat($foo, 7);

Answer 4

for ($i = 0, $i <= 7, $i++) {
    echo $foo;
}

Answer 5

Use a for loop.....................
