Summary<\/strong>: in this tutorial, you will learn a couple of ways to create a new file in PHP.<\/p>\n\n\n\n

Creating a file using the fopen() function #<\/a><\/h2>\n\n\n\n

The fopen()<\/code> function opens a file<\/a>. It also creates a file if the file doesn’t exist. <\/p>\n\n\n\n

Here’s the syntax of the fopen()<\/code> function:<\/p>\n\n\n

fopen ( \n   string $filename , \n   string $mode , \n   bool $use_include_path = false<\/span> , \n   resource $context = ? \n) : resource<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
To create a new file using the fopen()<\/code> function, you specify the $filename<\/code> and one of the following modes:<\/p>\n\n\n\n
Mode<\/th>File Pointer<\/th><\/tr><\/thead>
‘w+’<\/td>At the beginning of the file<\/td><\/tr>
‘a’<\/td>At the end of the file<\/td><\/tr>
‘a+’<\/td>At the end of the file<\/td><\/tr>
‘x’<\/td>At the beginning of the file<\/td><\/tr>
‘x+’<\/td>At the beginning of the file<\/td><\/tr>
‘c’<\/td>At the beginning of the file<\/td><\/tr>
‘c+’<\/td>At the beginning of the file<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
Except for the 'a'<\/code> and 'a+'<\/code>, the file pointer is placed at the beginning of the file. <\/p>\n\n\n\n
If you want to create a binary file, you can append the character 'b'<\/code> to the $mode<\/code> argument. For example, the 'wb+'<\/code> opens a binary file for writing.<\/p>\n\n\n\n
The following example uses fopen()<\/code> to create a new binary file and write some numbers to it:<\/p>\n\n\n
<?php<\/span>\n\n$numbers = [1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>];\n$filename = 'numbers.dat'<\/span>;\n\n$f = fopen($filename, 'wb'<\/span>);\nif<\/span> (!$f) {\n    die<\/span>('Error creating the file '<\/span> . $filename);\n}\n\nforeach<\/span> ($numbers as<\/span> $number) {\n    fputs($f, $number);\n}\n\nfclose($f);<\/span><\/code><\/span>Code language:<\/span> HTML, XML<\/span> (<\/span>xml<\/span>)<\/span><\/small><\/pre>\n\n\n
How it works.<\/p>\n\n\n\n
