In this tutorial, we would cover string manipulation in PHP.<\/p>\n
Just like in other languages, string in PHP are a sequence of characters. Some examples of strings are given below:<\/p>\n
$string1 = \"You can learn PHP\";\r\n$string0 = \"\"; \/\/this is an empty string\r\n$string2 = 'This is a singly quoted string';\r\n<\/pre>\n<\/p>\n
About singly and double-quoted strings<\/strong><\/p>\n
Singly quoted strings are just output literally. However, double quoted strings would replace any containing variables with the actual values of those variables. An example is given below<\/p>\n
<?php<\/span>\r\n $name<\/span> =<\/span> \"Kindson\"<\/span>;\r\n\r\n echo<\/span> \"My name is <\/span>$name<\/span> <br>\"<\/span>;\r\n echo<\/span> 'My name is $name'<\/span>;\r\n?><\/span> \r\n<\/pre>\nThe result of the above code is shown below<\/p>\n
My name is Kindson\r\nMy name is $name\r\n<\/pre>\n<\/p>\n
Escape Sequences<\/strong><\/p>\n
This are special combination of characters used certain operations such as:<\/p>\n
\n
- \\n represents the newline character<\/li>\n
- \\r represents the carriage-return character<\/li>\n
- \\t represents the tab character<\/li>\n
- \\$ represents the dollar sign itself ($)<\/li>\n
- \\” represents a single double-quote (“)<\/li>\n
- \\\\ represents a single backslash (\\)<\/li>\n<\/ul>\n
<\/p>\n
String Concatenation Operator<\/strong><\/p>\n
The dot (.) operator is used to concatenate two variables.<\/p>\n
The strlen() function<\/strong><\/p>\n
This function is used to find the length of a string. For example<\/p>\n
<?php<\/span>\r\n echo<\/span> strlen<\/span>(\"Learning PHP is fun\"<\/span>);\r\n?><\/span> \r\n<\/pre>\n<\/p>\n
The strpos() function<\/strong><\/p>\n
This function is used to search for a string or character within a string. If it finds a match, then the position of the first match is found, else, it will return false.<\/p>\n
