The PHP function echo   prints out its input to the web server response   echo  Hello World       prints out Hello World  to the web server response   echo   lt prev gt       prints out the tag  to the web server response   echo do not require valid HTML tags  You can use PHP to print XML  images  excel  HTML and so on    lt prev  is not a HTML tag  Is is a valid XML tag  but since I don t know what page you are working in  i cannot tell you what it is  Maybe it is the root tag of a XML page  or a miswritten  lt pre  tag

The  lt prev gt  tag doesn t exist  but it s probably the  lt pre gt  HTML tag to put around debug output  to improve readability  It s not a secret PHP hack

The  lt pre gt  is used to define pre-formatted text  The text within  lt pre gt  tag is displayed in a fixed-width font and it preserves both spaces and line breaks that are present in the text Here I m printing a JSON FILE without  lt pre gt  tag and then with  lt pre gt  tag  Without  lt pre gt  tag https   i stack imgur com ofRn8 jpg With  lt pre gt  tag https   i stack imgur com XzDVg jpg

lt pre gt   is an HTML tag  If you insert this line of code in your program  echo   lt pre gt     then you will enable the viewing of multiple spaces and line endings  Without this  all  n   r and other end line characters wouldn t have any effect in the browser and wherever you had more than 1 space in the code  the output would be shortened to only 1 space  That s the default HTML  In that case only with  lt br gt  you would be able to break the line and go to the next one   For example   the code below would be displayed on multiple lines  due to  n line ending specifier     lt  php     echo   lt pre gt        printf   lt span style  color   X X X  gt Hello lt  span gt  n   65  127  245       printf  Goodbye      gt    However the following code  would be displayed in one line only  line endings are disregarded     lt  php     printf   lt span style  color   X X X  gt Hello lt  span gt  n   65  127  245       printf  Goodbye      gt

I think you re talking about  lt pre gt  lt  pre gt   element is displayed in a fixed-width font  and it preserves both spaces and line breaks   try printing an array with a     lt pre gt    and whitout    lt pre gt       arr   array 1  2  3    echo   lt pre gt    print r  arr   echo   lt  pre gt     print r  arr

here whatever we write in between the pre tags  it will be interpreted same as html pre tag  ex    lt  php echo   lt pre gt    echo   code here  will be displayed as it  is    namaste    echo  this line get printed in new line   echo   lt  pre gt    echo  Now pre ended    echo  this line gets joined to above line     gt    and content b w   s font also changes

if you put text within an HTML  tag  all spaces and line breaks will be preserved   Otherwise  the default behaviour is to remove multiple spaces and keep only one space  and ignore line breaks  unless you use the  tag    I d like to say it s from the time before CSS - not necessarily used to make text more legible  only more formatted
