Old Solution:

$aArr = array("Have you ever seen",

"the beauty of the world.",

"The wonderful creation of the Lord." );

foreach($aArr as $sString) {

    print $sString;

}

Other Solution:

$aArr = array("Have you ever seen",

"the beauty of the world.",

"The wonderful creation of the Lord." );

$sString = implode(" ", $aArr);

print $sString;

In Action: I want to execute a linux command via PHP and get its result and extract the desire content. The example below will try to extract the ip address from the ifconfig command

exec("ifconfig", $aOutput);

$sTempString = implode(" ", $aOutput);

preg_match("/inet\saddr:(.*?)\s/i", $sTempString, $aMatch);

print $aMatch[1]; //

$sMyName = “Darwin”;

print $sMyName[1]; // will print the letter “a”

Heredocs start with <<< and a token or also known as delimiting identifier. The token or delimiting identifier don’t leading or trailing whitespace and followed by semicolon a to end the statement.

Example: We wanted to print this string

The quick brown fox

jumps over the lazy dog.

But what is the name of that dog 

whom the fox jumped over.

Usually we will use the print built in function of php and put line breaks to separate the lines

print "The quick brown fox \n";

print "jumps over the lazy dog. \n";

print "But what is the name of that dog \n"; 

print "whom the fox jumped over \n";

In heredoc we literally print these sequence string without having to print all the lines 1 by 1;

Using heredoc

print <<< DOGS

The quick brown fox

jumps over the lazy dog.

But what is the name of that dog 

whom the fox jumped over.

DOGS; 

Heredocs in HTML

$sAnimal = "cat";

$aZoo = array("elephant","zebra","monkey","lion","bear");

print <<< ZOO

There are different animals in the zoo.

It includes <b>$aZoo[1], $aZoo[3].</b>

There are also <font color="red">$sAnimal</font> here.

ZOO;
