Example using escape slash: He said, "Hello, how are you?"
Example not using escape slash: He said, "Hello, how are you?"
In PHP, the escape slash (\) is used to include special characters in a string. For example, to include double quotes inside a string that is enclosed in quotes, you use the escape slash: \". Without the escape slash, you can either use single quotes to inlcude double quotes or use double quotes directly within a string enclosed in single quotes.
<?php // Example using escape slash $example_with_escape = "He said, \"Hello, how are you?\""; echo "<p>Example using escape slash: $example_with_escape</p>"; //Example not using escape slash $example_without_escape = "He said, "Hello, how are you?"'; echo "<p>Example not using escape slash: $example_without_escape</p>";?>
