If Statement and Nested if Statement<\/h1>\n\n\n\n

If statement<\/strong><\/em> is used to execute when a statement or a block of statement only if the condition is fulfilled or true. <\/p>\n\n\n\n

Syntax<\/h2>\n\n\n\n

For One Statement:-<\/h3>\n\n\n\n

if(condition\/expression)
statement;<\/em><\/p>\n\n\n\n

For more than one Statement:-<\/h3>\n\n\n\n

if(condition\/expression)
{
Blocks of statement;
}<\/em><\/p>\n\n\n\n

OR<\/em><\/strong><\/p>\n\n\n\n

if(condition\/statement):
Blocks of statements;
endif;<\/em><\/p>\n\n\n\n

Sample Program<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Output<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Nested if Statement<\/h2>\n\n\n\n

We can make nesting statement by nesting the if statement<\/strong>. It means when we insert a second if statement<\/em> inside an if statement<\/em>, we call it nested if statement<\/strong><\/em> or nesting the if statement<\/strong>.<\/p>\n\n\n\n

Sample Program<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Output<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

if else and Nested if else Statement.<\/h1>\n\n\n\n

A statement executes code if if_condition<\/em> is true and executes another code if if_condition<\/em> is false.<\/p>\n\n\n\n

Syntax<\/h3>\n\n\n\n

if(condition\/expression)
{
Statement1;
}
else echo “Statement2”;<\/em><\/p>\n\n\n\n

Example –<\/strong> when Condition is True then, if_condition<\/strong> executes. See Below<\/em><\/p>\n\n\n\n

Sample Program<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Output<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

when Condition is False then, else_condition<\/strong> executes. See Below <\/em><\/p>\n\n\n\n

Sample Program<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Output <\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Nested if else Statement<\/h2>\n\n\n\n

we insert a second if_else<\/em> statement inside an if_else<\/em> statement<\/em>, we call it nested _if_else statement<\/em><\/strong>.<\/p>\n\n\n\n

syntax<\/h3>\n\n\n\n

if(condition\/expression)
{
if(condition\/expression)
{
Statement1;
}
else echo “Statement2”;
}
else echo “Statement2”;<\/em><\/p>\n\n\n\n

Sample Program<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

In the above program, The first Condition<\/em> is true, then it enters in 2nd condition<\/em> to check and when the 2nd condition<\/em> is true then it prints that statement and skips other else statements<\/em>. See the Output<\/strong><\/em> below: <\/p>\n\n\n\n
