In both types of string:<\/p>\n\n\n\n
' needs to be \\'<\/code><\/pre>\n\n\n\n \\ needs to be \\\\<\/code><\/pre>\n\n\n\nIn ” ” strings:<\/p>\n\n\n\n
\" needs to be \\\"<\/code><\/pre>\n\n\n\n \\t tab<\/code><\/pre>\n\n\n\n \\n new line<\/code><\/pre>\n\n\n\n \\r return<\/code><\/pre>\n\n\n\nNote, using say ‘\\n’ will not create a newline character, it will create the characters \\n !!!!! \\n only works in a “” string!!<\/em><\/p>\n\n\n\nJoining strings<\/h4>\n\n\n\n
Use the period character ‘.’<\/p>\n\n\n\n
You can also use .=<\/p>\n\n\n\n
$body = \"Some\" . \" text\";\n $body .= \"Some more text\";<\/code><\/pre>\n\n\n\nIs String<\/h4>\n\n\n\n if (\n isset($MyString) &&\n is_string($MyString) &&\n strlen($MyString) > 0\n )\n {\n }<\/code><\/pre>\n\n\n\nIs String Empty<\/h4>\n\n\n\n\t$my_string = trim($my_string);\n\tif (!empty($my_string))\n\t\t\/\/Do something<\/code><\/pre>\n\n\n\nLength<\/h4>\n\n\n\n $length = strlen($MyString);<\/code><\/pre>\n\n\n\n\u2018 vs \u201c<\/h4>\n\n\n\n
\u2018 single quotes assigns a string using its exact contents. So if you want to include variables you have to do this:<\/p>\n\n\n\n
echo 'His name is ' . $name . ' and his age is' . $age';<\/code><\/pre>\n\n\n\n\u201d double quotes assigns a string but if the string contains a variable name the php parser will attempt to evaluate it, so you can use it like this:<\/p>\n\n\n\n
echo \"His name is $name and his age is $age\";<\/code><\/pre>\n\n\n\nVariables and arrray values in a string<\/h4>\n\n\n\n echo \"His name is $name\";\n echo \"His name is ${name}y\"; \/\/<<Curley braces can be used if you need to force PHP to see a variable name within other characters\n echo \"His name is ${MyArray['name']}\"; \/\/<<Also allows array values to be included<\/code><\/pre>\n\n\n\nEcho A Block Of Text<\/h4>\n\n\n\necho \"Some\n\ntext\n\nblah blah\";<\/code><\/pre>\n\n\n\nAbbreviated way of inserting an echo in HTML<\/h5>\n\n\n\n
\u201c<?=\u201d can be used in place of \u201c<?php echo\u201d<\/p>\n\n\n\n
<?=\"<p>Hello world<\/p>\";?>\n\nIs the same as:\n<?php echo \"<p>Hello world<\/p>\";?><\/code><\/pre>\n\n\n\nHeredoc string<\/h4>\n\n\n\n
