Escape Sequence in PHP "\"
Sample 1 : What is Escape Sequence?
Escape Sequence is the combination of escape symbol "\" and a letter coming after it.Escape character "\" is used to show double quotes, dollar sign, single quote, back slash, curly brackets, or other brackets.
It works within double quotes. "" only.
Sample 2 : Types of Escape Sequences
I am going to describe 8 types of Escape Sequence- \" = It is used to show a certain value within double quotes like "Sami"
- \" = It is used to show a certain value within single quote like \'Sami\'
- \n = It is used to transfer remaining characters in new line like Samee Ullah
Feroz - \t = It is used to add 3 spaces within two words or characters like Samee Ullah Feroz
- \r = It is used for courage Return like Samee Ullah Feroz
- \$ = It is used to show dollar sign as not the part of variable. like 1000 $
- \ = It is used to print a tractor as back slash not as escape character. like \Sami
Sample 3 : Example of \n , \t, \r Sequences.
