how to stop a loop at certain result in PHP language?

Question

how to stop a loop from continuing when having a certain value?

Answer 1

if(value is reached)
break;

Use this when you want to exit a loop when you a somewhere in the middle of it. Otherwise, the for and while constructs will break for you.

Answer 2

You can either use break; statement. Or you can use while/do-while loop

like
while($strValue!="dummytext")
{
$strValue = reset value;
}

or

do
{
$strValue=reset value;
}while($strValue!="dummytext");
