: [[Image:Owl icon.jpg]] How to debut the cUrl command: (1) Enable the [https://ec.haxx.se/usingcurl/verbose verbose] option e.g. "... run the command with the {{kbd | key=<nowiki>-v</nowiki>}} / {{kbd | key=<nowiki>--verbose</nowiki>}} option to get more information." or (2) Enable the [https://ec.haxx.se/usingcurl/verbose/trace trace options] e.g. {{kbd | key=<nowiki>--trace-ascii [filename]</nowiki>}} Note: trace options will be override by verbose option if enable both options. | : [[Image:Owl icon.jpg]] How to debut the cUrl command: (1) Enable the [https://ec.haxx.se/usingcurl/verbose verbose] option e.g. "... run the command with the {{kbd | key=<nowiki>-v</nowiki>}} / {{kbd | key=<nowiki>--verbose</nowiki>}} option to get more information." or (2) Enable the [https://ec.haxx.se/usingcurl/verbose/trace trace options] e.g. {{kbd | key=<nowiki>--trace-ascii [filename]</nowiki>}} Note: trace options will be override by verbose option if enable both options. | ||
== How to resolve Command Execution: Works in DOS/Terminal but Not in PHP == | |||
Often, commands that run perfectly when manually executed in DOS or the Windows terminal (like [https://conemu.github.io/ ConEmu]) might not produce the expected outcome when run through PHP. A common issue is the command not generating the anticipated file. | |||
Example cURL command for Windows terminal | |||
<pre> | |||
curl "https://www.example.com/path/to/resource/" ^ | |||
-H "authority: www.example.com" ^ | |||
-H "accept: text/html" ^ | |||
--data-raw "PARAMS" --compressed > output.html | |||
</pre> | |||
Solution | |||
* '''Single Continuous String in PHP''': In PHP, when executing a shell command, avoid using the caret (^) for multi-line commands, which is typical in the Command Prompt. Instead, ensure the command is one continuous string. | |||
* '''Unsupported curl Options''': If you encounter an error like "curl: option --compressed: the installed libcurl version doesn't support this", it's a clear indication to remove or adjust the problematic option in the curl command. | |||
Revised cURL command for PHP | |||
<pre> | |||
curl "https://www.example.com/path/to/resource/" -H "authority: www.example.com" -H "accept: text/html" --data-raw "PARAMS" > output.html | |||
</pre> | |||
